Sequential evaluation—substantial gainful activity

Section 404.1520 requires disability claims to be evaluated through five sequential steps, including assessment of substantial gainful activity, severity, the Listings, residual functional capacity for past work, and other work in the national economy.

DE LOPEZ v. Astrue · filed 2009-02-03(b), (c), (d), (f), (g)

The Commissioner has promulgated regulations establishing a five-step sequential evaluation process for the ALJ to follow in a disability case. 20 C.F.R. § 404.1520. In the First Step, the ALJ must determine whether the claimant is currently engaged in substantial gainful activity. 20 C.F.R. § 404.1520(b). If not, in the Second Step, the ALJ must determine whether the claimant has a severe impairment or combination of impairments significantly limiting her from performing basic work activities. 20 C.F.R. § 404.1520(c). If so, in the Third Step, the ALJ must determine whether the claimant has an impairment or combination of impairments that meets or equals the requirements of the Listing of Impairments (“Listing”), 20 C.F.R. Part 404, Subpart P, App. 1. 20 C.F.R. § 404.1520(d). If not, in the Fourth Step, the ALJ must determine whether the claimant has sufficient residual functional capacity despite the impairment or various limitations to perform her past work. 20 C.F.R. § 404.1520(f). If not, in Step Five, the burden shifts to the Commissioner to show the claimant can perform other work that exists in significant numbers in the national economy. 20 C.F.R. § 404.1520(g).

Section 404.1520 requires the ALJ to use a five-step sequential evaluation of disability claims, including determining at step two whether the claimant has a severe impairment.

Pruitt v. Astrue · filed 2010-07-14

In determining whether a person is disabled, the Regulations require the A.L.J. to perform a sequential five-step analysis. 20 C.F.R. §§ 404.1520, 416.920. In step one, the A.L.J. must determine whether the claimant is currently engaged in substantial gainful activity. In step two, the A.L.J. must determine whether the claimant is suffering from a severe impairment. If the claimant fails to show that his or her impairment is severe, he or she is ineligible for benefits. ... Under step two of the sequential evaluation, the A.L.J. is required, in the first instance, to evaluate the severity of Plaintiffs mental impairments.

Section 404.1520 requires the Commissioner to decide disability claims through a five-step sequential process, stopping when disability or non-disability is established and shifting the burden to the Commissioner at step five.

Jackson v. Astrue · filed 2010-08-23(a)(4)

To determine disability, the Commissioner uses a five-step sequential analysis. ... If a finding of disability or non-disability can be made at any point in the sequential process, the Commissioner will not review the claim further. ... At step one, the Commissioner must determine whether the claimant is engaged in any substantial gainful activity. ... If the claimant is not engaged in substantial gainful activity, step two requires the Commissioner to determine whether the claimant is suffering from a severe impairment or a combination of impairments that is severe. ... When a claimant’s impairment or its equivalent matches an impairment in the listing, the claimant is presumed disabled. ... At step four, the Commissioner determines whether the claimant retains the RFC to perform his past relevant work. ... If the claimant is unable to return to his past relevant work, step five requires the Commissioner to determine whether the claimant’s impairments preclude him from adjusting to any other available work. ... At this last step, the burden is on the Commissioner to show that the claimant is capable of performing other available work before denying disability benefits.

Section 404.1520 requires disability claims to be evaluated sequentially: substantial gainful activity is considered first, followed by whether the claimant has a severe impairment; failure at either step ends the inquiry with a finding of not disabled.

YTTRIE v. Astrue · filed 2010-07-26(b), (c)

At Step One, the Commissioner determines whether the claimant is currently engaged in substantial gainful activity. 20 C.F.R. § 404.1520(b). ... If the claimant is engaged in substantial gainful activity, he or she is found not disabled, regardless of medical condition, age, education, or work experience, and the inquiry ends; if not, the inquiry proceeds to Step Two. ... Step Two requires a determination whether the claimant is suffering from a severe impairment. ... A severe impairment is one which significantly limits the claimant’s physical or mental ability to do basic work activities. 20 C.F.R. § 404.1520(c). The claimant’s age, education, and work experience are not considered in making a Step Two severity determination. 20 C.F.R. § 404.1520(c). If the claimant suffers a severe impairment, then the inquiry moves on to Step Three; if not, then the claimant is found to be not disabled, and the inquiry ends. ... In performing the Step Two analysis in this case, the ALJ noted that on or before the onset date, Claimant had the following impairments: degenerative disease of the lumber spine, complex regional pain syndrome, and depression/anxiety. (Tr. 15.) Because these medically determinable conditions significantly limited Claimant’s ability to perform basic work activity, the ALJ recognized these impairments as “severe impairments” under 20 C.F.R. § 404.1520(e). Neither party disputes this determination. Thus, the ALJ’s Step Two determination is affirmed.

Section 404.1520 establishes a five-step process for deciding disability, including whether the claimant can perform past relevant work and, if not, whether work exists in the national economy.

Loveland v. Astrue · filed 2010-08-25

The Commissioner has promulgated regulations, found at 20 C.F.R. § 404.1520, establishing a five-step sequential evaluation process to determine disability. The Commissioner begins by deciding whether the claimant is engaged in substantial gainful activity. If so, benefits are denied. If not, the Commissioner decides whether the claimant has a "severe" impairment or combination of impairments. A severe impairment is one which significantly limits a person's physical or mental ability to do basic work activities. 20 C.F.R. § 404.1521(a). If the claimant does not have a severe impairment that meets the duration requirement, the claim is denied. If the impairment or combination of impairments is severe and meets the duration requirement, the Commissioner determines at step three whether the claimant's impairment meets or is equal to one of the deemed-disabling impairments listed in the Commissioner's regulations. If not, the Commissioner asks at step four whether the claimant has the RFC to perform her past relevant work. If so, the claimant is not disabled. If she cannot perform her past relevant work, the burden of proof shifts at step five to the Commissioner to demonstrate that the claimant retains the RFC to perform work that is available in the national economy and that is consistent with the claimant's vocational factors.

Burgin vs Commissioner of Social Security · filed 2011-03-30

To obtain Social Security disability benefits, a claimant must show: (1) he is not performing substantial gainful activity; (2) he has a severe impairment; (3) the impairment or combination of impairments meets or equals an impairment listed in the regulations; or (4) he cannot return to past work; and (5) he cannot perform other work based on his age, education, and experience. Phillips v. Barnhart, 357 F.3d 1232, 1237 (11th Cir. 2004); 20 C.F.R. §§ 404.1520 and 416.920.

Section 404.1520(a)(4) requires disability claims to be evaluated through a five-step sequence: substantial gainful activity, severe impairment, listed impairment, past relevant work, and adjustment to other work.

Courter v. Commissioner of Social Security · filed 2012-05-07(a)(4)

Corresponding regulations outline a five-step sequential process to determine whether an individual qualifies as disabled. See 20 C.F.R. §§ 404.1520, 416.920. That process provides: First, the claimant must demonstrate that he has not engaged in substantial gainful activity during the period of disability. Second, the claimant must show that he suffers from a severe medically determinable physical or mental impairment. Third, if the claimant shows that his impairment meets or medically equals one of the impairments listed in 20 C.F.R. Pt. 404, Subpt. P, App. 1, he is deemed disabled. Fourth, the ALJ determines whether, based on the claimant’s residual functional capacity, the claimant can perform his past relevant work, in which case the claimant is not disabled. Fifth, the ALJ determines whether, based on the claimant’s residual functional capacity, as well as his age, education, and work experience, the claimant can make an adjustment to other work, in which case the claimant is not disabled.

Section 404.1520(a)(4) establishes a five-step sequential process for evaluating disability claims, with the claimant bearing the burden through step four and the SSA bearing it at step five.

Dubois v. Astrue · filed 2012-06-20(a)(4)

A five-step process is used to evaluate an application for social security benefits. 20 C.F.R. §§ 404.1520(a)(4), 416.920(a)(4). The claimant bears the burden, through the first four steps, of proving that he is disabled, i.e., that (1) he is not engaged in substantial gainful activity; (2) he has a severe impairment; (3) the impairment meets or equals a specific impairment listed in the Social Security regulations; and (4) the impairment prevents or prevented him from performing past relevant work. Id.; see Freeman v . Barnhart, 274 F.3d 606, 608 (1st Cir. 2001). At the fifth step, the SSA bears the burden of showing that the claimant has the residual functional capacity to perform other work that may exist in the national economy. Freeman, 274 F.3d at 608; see 20 C.F.R. §§ 404.1520(a)(4)(v), 416.920(a)(4)(v). “[A]ll five steps are not applied to every applicant, as the determination may be concluded at any step along the process.” Freeman, 274 F.3d at 608.

Gould v. SSA · filed 2012-10-31

When determining whether a claimant is disabled, the ALJ is also required to make the following five inquiries: (1) whether claimant is engaged in substantial gainful activity; (2) whether claimant has a severe impairment; (3) whether the impairment meets or equals a listed impairment; (4) whether the impairment prevents claimant from performing past relevant work; and (5) whether the impairment prevents claimant from doing any other work. 20 C.F.R. § 404.1520.

Section 404.1520 requires disability claims to be evaluated through sequential steps, including whether the claimant has a severe impairment.

Hinton v. Astrue · filed 2013-02-11(c)

The Commissioner has established a five-step process for determining whether a person is disabled. ... First, the claimant cannot be presently engaged in “substantial gainful activity.” ... Second, the claimant must have a severe impairment. ... At the third step in the sequential evaluation process, the ALJ must determine whether the claimant has a severe impairment, or combination of impairments, which meets or equals one of the impairments listed in the regulations and whether such impairment meets the twelve-month durational requirement. ... At step four, the ALJ determines whether claimant can return to her past relevant work, “reviewing] [the claimant’s] [RFC] and the physical and mental demands of the work [claimant has] done in the past.” ... If the ALJ holds at step four of the process that a claimant cannot return to past relevant work, the burden shifts at step five to the Commissioner to establish that the claimant maintains the RFC to perform a significant number of jobs within the national economy. ... For the foregoing reasons, the ALJ did not err in not finding Plaintiffs depression to be a severe impairment.

Blankenship v. Comm'r of Social Security · filed 2015-08-26(a)(4)

The Commissioner conducts a five-step sequential analysis to determine if a claimant is disabled within the meaning of the Social Security Act: (i) At the first step, we consider your work activity, if any. If you are doing substantial gainful activity, we will find that you are not disabled. (ii) At the second step, we consider the medical severity of your impairment(s). If you do not have a severe medically determinable physical or mental impairment that meets the duration requirement in § 404.1509, or a combination of impairments that is severe and meets the duration requirement, we will find that you are not disabled. (iii) At the third step, we also consider the medical severity of your impairment(s). If you have an impairment(s) that meets or equals one of our listings in appendix 1 of this subpart and meets the duration requirement, we will find that you are disabled. (iv) At the fourth step, we consider our assessment of your residual functional capacity and your past relevant work. If you can still do your past relevant work, we will find that you are not disabled. (v) At the fifth and last step, we consider our assessment of your residual functional capacity and your age, education, and work experience to see if you can make an adjustment to other work. If you can make an adjustment to other work, we will find that you are not disabled. If you cannot make an adjustment to other work, we will find that you are disabled. 20 C.F.R. §§ 404.1520(a)(4), 416.920(a)(4).

Section 404.1520 establishes a five-step sequential evaluation for disability claims, ending with whether the claimant can perform other substantial gainful activity considering the claimant’s remaining capacities and vocational factors.

Piziak v. Berryhill · filed 2017-03-22

The Social Security Regulations establish a “sequential evaluation” for the adjudication of disability claims. 20 C.F.R. § 404.1520. If an individual is found “not disabled” at any step, further inquiry is unnecessary. Id. § 404.1520(a). The first inquiry under the sequence is whether a claimant is currently engaged in substantial gainful employment. Id. § 404.1520(b). If the claimant is not, the second inquiry is whether claimant suffers from a severe impairment. Id. § 404.1520(c). If a severe impairment is present, the third inquiry is whether such impairment meets or equals any of the impairments listed in Appendix 1 to Subpart P of the Administrative Regulations No. 4. Id. § 404.1520(d). If it does, the claimant is found disabled and awarded benefits. Id. If it does not, the fourth inquiry is whether the claimant’s impairments prevent the performance of past relevant work. Id. § 404.1520(f). By satisfying inquiry four, the claimant establishes a prima facie case of disability. Hall v. Harris, 658 F.2d 260, 264 (4th Cir. 1981). The burden then shifts to the Commissioner, McLain v. Schweiker, 715 F.2d 866, 868-69 (4th Cir. 1983), and leads to the fifth and final inquiry: whether the claimant is able to perform other forms of substantial gainful activity, considering claimant’s remaining physical and mental capacities and claimant’s age, education and prior work experience. Id. § 404.1520(g). The Commissioner must show two things: (1) that the claimant, considering claimant’s age, education, work experience, skills and physical shortcomings, has the capacity to perform an alternative job, and (2) that this specific job exists in the national economy. McLamore v. Weinberger, 538 F.2d 572, 574 (4th Cir. 1976).

Mauro v. Berryhill · filed 2017-09-18(a)(4)

■ Regulations issued pursuant to the Social Security Act set forth a five-step process that the Commissioner must use in evaluating a disability claim. See 20 C.F.R. § 404.1520(a)(4); see also Burgess, 537 F.3d at 120 (describing the five-step process). First, the Commissioner must determine whether the claimant is currently engaged in any “substantial gainful activity.” 20 C.F.R. § 404.1520(a)(4)(I). Second, if the claimant is not engaged in substantial gainful activity, the Commissioner must decide if the claimant has a “severe medically determinable physical or mental impairment,” id. § 404.1520(a)(4)(ii), which is an impairment or combination of impairments that “significantly limits [the claimant’s] physical or mental ability to do basic work activities,” id § 404.1520(c). Third, if the claimant’s impairment is severe and is listed in 20 C.F.R, Part 404, Subpart P, Appendix 1, or is equivalent to one of the listed impairments, the claimant must be found disabled regardless of his age, education, or work experience. See id. § 404.1520(a)(4)(iii). Fourth, if the claimant’s impairment is not listed and is not equal to one of the listed impairments, the Commissioner must review the claimant’s RFC to determine if the claimant is able to do work he or she has done in the past, i.e., “past relevant work,” Id. § 404.1520(a)(4)(iv). If the claimant is able to do such work, he or she is not disabled. Id. Finally, if the claimant is unable to-perform past relevant work, the Commissioner must decide if the claimant’s RFC permits the claimant to do other work. Id § 404.1520(a)(4)(v).

Section 404.1520 establishes a five-step sequential process for deciding whether a claimant is disabled, including consideration of work activity, severe impairments, residual functional capacity, past work, and other work.

Dawn Wilson v. Comm'r of Soc. Sec. · filed 2019-08-06(a)

Under the framework for Social Security disability determinations at 20 C.F.R. § 404.1520(a)-(f), Wilson has met the first three steps of the five-step sequential analysis: she met insured status requirements through March 31, 2011, she has not engaged in substantial gainful activity since the alleged onset date in March 2004, and she had the severe impairments of fibromyalgia, carpal tunnel syndrome, and facet arthropathy through the date last insured, though her impairments are not so severe that we end the analysis at step three. See id. ... At step four, Wilson does not have the residual functional capacity to perform her past relevant work as a mail handler, but we consider whether her residual functional capacity, age, education, and past experience permit her to do other work. See id. § 404.1520(g). ... Finally, at step five, “the Commissioner must make a finding ‘supported by substantial evidence that [the claimant] has the vocational qualifications to perform specific jobs’” which may be shown through the testimony of a vocational witness in response to a hypothetical question which accurately portrays the claimant’s “‘individual physical and mental impairments.’”

Section 404.1520 establishes a sequential evaluation process for disability claims, and benefits are available only when the claimant cannot perform other work.

Owens v. Commissioner of Social Security · filed 2019-08-26(a), (g)

These regulations establish a “sequential evaluation process” to determine whether a claimant is disabled. 20 C.F.R. §§ 404.1520, 416.920. If an individual is found disabled at any point in the sequential review, further inquiry is unnecessary. 20 C.F.R. §§ 404.1520(a), 416.920(a). Under this process, the ALJ must determine, in sequence, the following: whether the claimant is currently engaged in substantial gainful activity; whether the claimant has a severe impairment, i.e., one that significantly limits the ability to perform work-related functions; whether the severe impairment meets or equals the medical criteria of 20 C.F.R. Part 404 Subpart P, Appendix 1; and whether the claimant can perform his or her past relevant work. If the claimant cannot perform the tasks required of his or her prior work, step five of the evaluation requires the ALJ to decide if the claimant can do other work in the national economy in view of his or her age, education, and work experience. 20 C.F.R. §§ 404.1520(a), 416.920(a). A claimant is entitled to benefits only if unable to perform other work. Bowen v. Yuckert, 482 U.S. 137, 140-42 (1987); 20 C.F.R. §§ 404.1520(g), 416.920(g).

Section 404.1520 requires disability claims to be evaluated through a five-step sequential process, from current substantial gainful activity through the claimant’s ability to perform other work.

Sorensen v. Saul · filed 2019-08-27(a)(4)

In determining whether a claimant qualifies as disabled within the meaning of the Act, the Social Security Administration employs a five-part sequential evaluation. See 20 C.F.R. § 404.1520. The analysis evaluates whether: (1) The claimant presently engages in substantial gainful activity; (2) The claimant has a medically severe physical or mental impairment or impairments; (3) The impairment is equivalent to one of the impairments listed in the appendix of the relevant disability regulation which preclude substantial gainful activity; (4) The impairment prevents the claimant from performing his or her past work; and (5) The claimant possesses a residual functional capacity to perform other work in the national economy considering his or her age, education, and work experience.

Section 404.1520 requires the Commissioner to evaluate disability claims through a five-step sequential process, addressing substantial gainful activity, severe impairment, listed impairments, past relevant work, and other work.

Rivera v. Commissioner of Social Security · filed 2019-09-10(a)(4)

Regulations issued pursuant to the Act set forth a five-step process that the Commissioner must use in evaluating a disability claim. See 20 C.F.R. §§ 404.1520(a)(4), 416.920(a)(4); see also Burgess, 537 F.3d at 120 (describing the five-step process). First, the Commissioner must determine whether the claimant is currently engaged in any “substantial gainful activity.” 20 C.F.R. §§ 404.1520(a)(4)(i), 416.920(a)(4)(i). Second, if the claimant is not engaged in substantial gainful activity, the Commissioner must decide if the claimant has a “severe medically determinable physical or mental impairment,” 20 C.F.R. §§ 404.1520(a)(4)(ii), 416.920(a)(4)(ii), which is an impairment or combination of impairments that “significantly limits [the claimant’s] physical or mental ability to do basic work activities,” 20 C.F.R. §§ 404.1520(c), 416.920(c). Third, if the claimant’s impairment is severe and is listed in 20 C.F.R. Part 404, Subpart P, Appendix 1, or is equivalent to one of the listed impairments, the claimant must be found disabled regardless of his age, education, or work experience. See 20 C.F.R. §§ 404.1520(a)(4)(iii), 404.1520(d), 416.920(a)(4)(iii), 416.920(d). Fourth, if the claimant’s impairment is not listed and is not equal to one of the listed impairments, the Commissioner must review the claimant’s RFC to determine if the claimant is able to do work he or she has done in the past, i.e., “past relevant work.” 20 C.F.R. §§ 404.1520(a)(4)(iv), 416.920(a)(4)(iv). If the claimant is able to do such work, he or she is not disabled. 20 C.F.R. §§ 404.1520(a)(4)(iv), 416.920(a)(4)(iv). Finally, if the claimant is unable to perform past relevant work, the Commissioner must decide if the claimant’s RFC, in addition to his or her age, education, and work experience, permits the claimant to do other work. 20 C.F.R. § 404.1520(a)(4)(v), 416.920(a)(4)(v).

McCall v. Commissioner of Social Security Administration · filed 2019-09-10(a)(4)

The Commissioner determines whether a claimant is disabled by way of a five-stage process. 20 C.F.R. § 404.1520(a)(4); Abbott v. Sullivan, 905 F.2d 918, 923 (6th Cir. 1990). First, the claimant must demonstrate that he is not currently engaged in “substantial gainful activity” at the time he seeks disability benefits. 20 C.F.R. §§ 404.1520(b) and 416.920(b). Second, the claimant must show that he suffers from a medically determinable “severe impairment” or combination of impairments in order to warrant a finding of disability. 20 C.F.R. §§ 404.1520(c) and 416.920(c). A “severe impairment” is one that “significantly limits ... physical or mental ability to do basic work activities.” Abbott, 905 F.2d at 923. Third, if the claimant is not performing substantial gainful activity, has a severe impairment (or combination of impairments) th at is expected to last for at least twelve months, and the impairment(s) meets a listed impairment, the claimant is presumed to be disabled regardless of age, education or work experience. 20 C.F.R. §§ 404.1520(d) and 416.920(d). Fourth, if the claimant’s impairment(s) does not prevent him from doing past relevant work, the claimant is not disabled. 20 C.F.R. §§ 404.1520(e)-(f) and 416.920(e)-(f). For the fifth and final step, even if the claimant’s impairment(s) does prevent him from doing past relevant work, if other work exists in the national economy that the claimant can perform, the claimant is not disabled. 20 C.F.R. §§ 404.1520(g) and 416.920(g), 404.1560(c).

The Commissioner has provided the ALJ with a five-step sequential analysis to use when evaluating the disabled status of each claimant. 20 C.F.R. § 404.1520. The ALJ must determine: (1) whether the claimant is currently engaged in substantial gainful activity; (2) if not, whether the claimant has a severe impairment; (3) if the claimant has a severe impairment, whether it meets or equals the criteria listed in 20 C.F.R. pt. 404, subpt. P, app. 1; (4) if the impairment does not satisfy one of the impairment listings, whether the claimant’s impairments prevent her from performing her past relevant work; and (5) if the claimant is incapable of performing her past relevant work, whether she can perform any other work which exists in the national economy, in light of her age, education, work experience and residual functional capacity. 20 C.F.R. § 404.1520. The claimant carries the initial burden of demonstrating by medical evidence that she is unable to return to her previous employment (steps 1-4). Dobrowolsky, 606 F.2d at 406.

Reynolds v. Commissioner of Social Security · filed 2019-09-30(a)(4)(i)-(v)

In evaluating the evidence presented at an administrative hearing, the ALJ must follow a sequential process in determining whether a person is disabled in general (see 20 C.F.R. §§ 404.1520, 416.920) – or continues to be disabled (see 20 C.F.R. §§ 404.1594, 416.994) – within the meaning of the Social Security Act. ... The first step requires the ALJ to determine whether the claimant is engaged in substantial gainful activity (“SGA”). ... If the claimant has engaged in SGA, disability benefits are denied, regardless of how severe her physical/mental impairments are and regardless of her age, education, and work experience. ... The second step requires a determination of whether the claimant has a medically determinable impairment, or combination of impairments, that is severe and meets the duration requirement. ... The third step requires the ALJ to determine the medical severity of any impairments; that is, whether the claimant’s impairments meet or equal a listed impairment under 20 C.F.R. Part 404, Subpart P, Appendix 1. ... The fourth step of the sequential process requires the ALJ to determine whether the claimant’s residual functional capacity (“RFC”) is sufficient for the claimant to perform past relevant work. ... In the fifth and final step, if it has been established that a claimant can no longer perform past relevant work because of her impairments, the burden shifts to the Commissioner to show that the claimant retains the ability to do alternate work and to demonstrate that such alternate work exists in significant numbers in the national economy.

Section 404.1520 establishes a five-step sequential process for evaluating disability claims, with benefits denied when a claimant is found able to perform available work at a step.

Ortiz v. Commissioner of Social Security · filed 2019-09-30(a)(4)

Claims for disability benefits are evaluated according to a five-step sequential process. 20 C.F.R. § 404.1520; Barnhart v. Thomas, 540 U.S. 20, 24–25 (2003); Cleveland v. Policy Mgmt. Sys. Corp., 526 U.S. 795, 804 (1999); Yuckert, 482 U.S. at 140–42. If it is determined that the plaintiff is not disabled at any step in the evaluation process, then the analysis will not proceed to the next step. 20 C.F.R. § 404.1520(a)(4). At step one, it is determined whether the plaintiff is working and thus engaged in “substantial gainful activity.” 20 C.F.R. § 404.1520(a)(4)(i). If he is, then disability benefits are denied. 20 C.F.R. § 404.1520(b). Step two requires the ALJ to determine whether the plaintiff has “a severe medically determinable physical or mental impairment” or severe combination of impairments. 20 C.F.R. § 404.1520(a)(4)(ii). ... At this final step, the ALJ evaluates whether the plaintiff’s RFC, combined with his age, education, and work experience, allows him to perform any other work that is available in the national economy. 20 C.F.R. § 404.1520(a)(4)(v).

These regulations establish a “sequential evaluation process” to determine whether a claimant is disabled. 20 C.F.R. §§ 404.1520, 416.920. If an individual is found disabled at any point in the sequential review, further inquiry is unnecessary. 20 C.F.R. §§ 404.1520(a), 416.920(a). Under this process, the ALJ must determine, in sequence, the following: whether the claimant is currently engaged in substantial gainful activity; whether the claimant has a severe impairment, i.e., one that significantly limits the ability to perform work-related functions; whether the severe impairment meets or equals the medical criteria of 20 C.F.R. Part 404 Subpart P, Appendix 1; and whether the claimant can perform his or her past relevant work. If the claimant cannot perform the tasks required of his or her prior work, step five of the evaluation requires the ALJ to decide if the claimant can do other work in the national economy in view of his or her age, education, and work experience. 20 C.F.R. §§ 404.1520(a), 416.920(a).

Second, if a claimant does not have any impairment or combination of impairments that significantly limit physical or mental ability to do basic work activities, then the claimant does not have a severe impairment and is not disabled. 20 C.F.R. § 404.1520(c). Third, if a claimant’s impairments meet or equal an impairment listed in 20 C.F.R. Part 404, Appendix 1, the claimant is disabled. 20 C.F.R. § 404.1520(d). Fourth, if a claimant’s impairments do not prevent doing past relevant work, the claimant is not disabled. 20 C.F.R. § 404.1520(e)-(f). Fifth, if a claimant’s impairments (considering RFC, age, education and past work) prevent doing other work that exists in the local or national economy, a finding of disabled is warranted. 20 C.F.R. § 404.1520(g).

Torrez v. Kijakazi · filed 2021-07-14(a)(4)(i), (a)(4)(v)

A five-step regulatory framework is used to determine whether an individual is disabled. 20 C.F.R. § 404.1520(a)(4); see also Bowen v. Yuckert, 482 U.S. 137, 140-142 (1987) (describing the five-step process). Steps One through Three require the claimant to prove: (1) she is not currently engaged in substantial gainful activity; (2) she suffers from a severe impairment; and (3) her condition meets or equals a listed impairment. 20 C.F.R. § 404.1520(a)(4)(i)-(iii). If the claimant does not suffer from a listed impairment or its equivalent, the Commissioner’s analysis proceeds to Steps Four and Five. Step Four requires the Commissioner to consider whether the claimant retains the RFC to perform past relevant work (PRW). Id. at § 404.1520(a)(4)(iv). The claimant bears the burden of demonstrating she is no longer able to return to her PRW. Pate-Fires, 564 F.3d at 942.

The sequential evaluation requires step-one screening for substantial gainful activity and, if the evaluation continues, consideration of past relevant work and adjustment to other work; an erroneous step-one finding is harmless when the ALJ proceeds through the remaining steps.

Mackey v. Commissioner Social Security Administration · filed 2021-09-01(a)(4)(i), (b), (a)(4)(iv), (a)(4)(v)

At step one of the sequential evaluation process, an ALJ must determine whether a claimant has engaged in substantial gainful activity (SGA) during his alleged period of disability. 20 C.F.R. § 404.1520(a)(4)(i). If so, he is not disabled for those periods of SGA. 20 C.F.R. § 404.1520(b). ... The error was harmless because the ALJ continued with the sequential evaluation process, regardless of the months when plaintiff was gainfully self-employed. Tr. 16. When an ALJ proceeds to the next step of the sequential evaluation process, any error at that step is harmless in the ALJ’s ultimate nondisability finding. Buck v.

Generally, the Commissioner must employ a five-step evaluation process to decide whether a claimant is disabled. 20 C.F.R. § 404.1520; see Bowen v. Yuckert, 482 U.S. 137, 140–42 (1987); Goodermote v. Secretary of Health & Human Services, 690 F.2d 5, 6–7 (1st Cir. 1982). In step one, the Commissioner determines whether the claimant is currently engaged in “substantial gainful activity.” If so, the claimant is not disabled. 20 C.F.R. § 404.1520(b). At step two, the Commissioner determines whether the claimant has a medically severe impairment or combination of impairments. 20 C.F.R. § 404.1520(c). If not, the disability claim is denied. At step three, the Commissioner must decide whether the claimant’s impairment is equivalent to a specific list of impairments contained in the regulations’ Appendix 1, which the Commissioner acknowledges are so severe as to preclude substantial gainful activity. 20 C.F.R. § 404.1520(d); 20 C.F.R. § 404, Subpt. P, App. 1. If the claimant’s impairment meets or equals one of the listed impairments, he is conclusively presumed to be disabled. If not, the evaluation proceeds to the fourth step, through which the ALJ assesses the claimant’s RFC and determines whether the impairments prevent the claimant from doing the work he has performed in the past. An individual’s RFC is his ability to do physical and mental work activities on a sustained basis despite limitations from his impairments. 20 C.F.R. § 404.1520(e) and 404.1545(a)(1). If the claimant is able to perform his previous work, he is not disabled. 20 C.F.R. § 404.1520(e). If he cannot perform this work, the fifth and final step asks whether the claimant is able to perform other work available in the national economy in view of his RFC, as well as age, education, and work experience. If the claimant cannot, then he is entitled to disability benefits. 20 C.F.R. § 404.1520(f).

Section 404.1520 requires the sequential evaluation of disability claims, including determining at step four whether a claimant can perform past relevant work and at step five whether the claimant can perform other substantial gainful activity available in significant numbers.

Carter v. Kijakazi · filed 2021-09-30(f), (g)

An ALJ must ascertain at step four of the sequential evaluation whether the claimant’s impairments prevent the performance of past relevant work. 20 C.F.R. § 404.1520(f). If so, the claimant has established a prima facie case of disability, and the burden shifts to the Commissioner to demonstrate, in the fifth and final step of the process, that the claimant is able to perform other forms of substantial gainful activity, given the claimant’s remaining physical and mental capacities, age, education, and prior work experiences.

Kimmerly v. Commissioner Social Security · filed 2022-03-30

In considering an application for supplemental security income or for disability benefits, the Social Security Agency is guided by the following sequential benefits analysis: at Step 1, the Commissioner asks if the claimant is still performing substantial gainful activity; at Step 2, the Commissioner determines if one or more of the claimant’s impairments are “severe;” at Step 3, the Commissioner analyzes whether the claimant’s impairments, singly or in combination, meet or equal a Listing in the Listing of Impairments; at Step 4, the Commissioner determines whether or not the claimant can still perform his or her past relevant work; and finally, at Step 5, if it is established that claimant can no longer perform his or her past relevant work, the burden of proof shifts to the agency to determine whether a significant number of other jobs which the claimant can perform exist in the national economy. See Combs v. Com’r of Soc. Sec., 459 F.3d 640, 643 (6th Cir. 2006); 20 C.F.R. §§404.1520, 416.920.

The ALJ reached this conclusion after proceeding through the five-step sequential analysis required by the Social Security Act. See 20 C.F.R. § 404.1520(a)(4). ... At step one of the five-step analysis, the ALJ must determine whether the claimant is engaging in substantial gainful activity (“SGA”). 20 C.F.R. § 404.1520(a)(4)(i). If a claimant is engaging in SGA, the claimant is not disabled, regardless of age, education, or work experience. ... At step three, the ALJ must determine whether an impairment or combination of impairments meets or equals the medical equivalent of an impairment listed in the version of 20 C.F.R. Part 404, Subpt. P, App. 1 that was in effect on the date of the ALJ’s decision. 20 C.F.R. §§ 404.1520(a)(4)(iii), 404.1525, 404.1526. ... Having assessed a claimant’s RFC, step four requires the ALJ to determine whether the claimant has the RFC to perform the requirements of his or her past relevant work. 20 C.F.R. § 404.1520(a)(4)(iv). ... At step five of the sequential analysis process, the ALJ considers the claimant’s age, education, and work experience to see if a claimant can make the adjustment to other work. 20 C.F.R. § 404.1520(a)(4)(v). ... If a claimant can adjust to other work, he or she will not be considered disabled. 20 C.F.R. § 404.1520(a)(4)(v).

Capalaces v. Kijakazi · filed 2024-01-08(a)

In making this determination at the administrative level, the ALJ follows a five-step sequential evaluation process. 20 C.F.R. §404.1520(a). Under this process, the ALJ must sequentially determine: (1) whether the claimant is engaged in substantial gainful activity; (2) whether the claimant has a severe impairment; (3) whether the claimant’s impairment meets or equals a listed impairment; (4) whether the claimant is able to do his or her past relevant work; and (5) whether the claimant is able to do any other work, considering his or her age, education, work experience and residual functional capacity (“RFC”). 20 C.F.R. §404.1520(a)(4). ... But our Step 2 inquiry does not end there. Even if we find that the ALJ erred in finding Capalaces’ mental impairments not severe at Step 2, we may still find that substantial evidence supported the ALJ’s opinion if the ALJ thoroughly considered the non-severe impairments at all subsequent steps in the disability analysis process. See McClease at *10, Salles at 145, n. 2 (3d Cir. 2007); Stouchko at *10. ... Moreover, even if the ALJ erred in determining that Capalaces’ psychological impairments were not severe, the error was harmless because the ALJ clearly and thoroughly considered Capalaces’ psychological impairments at each subsequent step in his analysis.

Section 404.1520 requires an ALJ to determine disability using a five-step sequential analysis.

Hess v. Commissioner of Social Security Administration · filed 2024-11-07

An ALJ is required to follow a five-step sequential analysis to make a disability determination: 1. Is the claimant engaged in substantial gainful activity? If so, the claimant is not disabled. 2. Does the claimant have a medically determinable impairment, or a combination of impairments, that is "severe"? If not, the claimant is not disabled. 3. Does the claimant’s impairment meet or equal one of the listed impairments and meet the duration requirement? If so, the claimant is disabled. If not, the ALJ proceeds to the next step. 4. What is the claimant’s residual functional capacity and can the claimant perform past relevant work? If so, the claimant is not disabled. If not, the ALJ proceeds to the next step. 5. Can the claimant do any other work considering the claimant’s residual functional capacity, age, education, and work experience? If so, the claimant is not disabled. If not, the claimant is disabled. 20 C.F.R. §§ 404.1520, 416.920; see Jordan v. Comm’r of Soc. Sec., 548 F.3d 417, 422 (6th Cir. 2008).

Benson v. O'Malley · filed 2025-06-20

In evaluating the evidence presented at an administrative hearing, the ALJ must follow a sequential process in determining whether a person is disabled in general (20 C.F.R. §§ 404.1520, 416.920) – or continues to be disabled (20 C.F.R. §§ 404.1594, 416.994) – within the meaning of the Social Security Act. The first step requires the ALJ to determine whether the claimant is engaged in substantial gainful activity (“SGA”). 20 C.F.R. §§ 404.1520(a)(4)(i), 416.920(a)(4)(i). ... The second step requires the ALJ to determine whether the claimant has a medically determinable impairment, or combination of impairments, that is severe and meets the duration requirement. 20 C.F.R. §§ 404.1520(a)(4)(ii), 416.920(a)(4)(ii). ... The third step requires the ALJ to determine the medical severity of any impairments; that is, whether the claimant’s impairments meet or equal a listed impairment under 20 C.F.R. Part 404, Subpart P, Appendix 1. 20 C.F.R. §§ 404.1520(a)(4)(iii), 416.920(a)(4)(iii). ... The fourth step of the evaluation process requires the ALJ to determine whether the claimant’s RFC is sufficient for the claimant to perform past relevant work. 20 C.F.R. §§ 404.1520(a)(4)(iv), 416.920(a)(4)(iv). ... In the fifth and final step, if it has been established that a claimant can no longer perform past relevant work because of her impairments, the burden shifts to the Commissioner to show that the claimant retains the ability to do alternate work and to demonstrate that such alternate work exists in significant numbers in the national economy. 20 C.F.R. §§ 404.1520(a)(4)(v), 416.920(a)(4)(v), 404.1520(f), 416.920(f); see also Garrison v.

Section 404.1520 establishes a sequential process for deciding disability claims, and further inquiry ends when a claimant is found disabled at an earlier step.

Hagins v. Commissioner of Social Security · filed 2025-08-26(a)

The Social Security Administration has established a standardized “sequential evaluation process” to determine whether a claimant is disabled. 20 C.F.R. § 404.1520. If an individual is found disabled at any point in the sequential review, further inquiry is unnecessary. 20 C.F.R. § 404.1520(a). Under this process, the ALJ must determine, in sequence: 1) whether the claimant is engaged in substantial gainful activity; 2) whether the claimant has a severe impairment, i.e., one that significantly limits the ability to perform work-related functions; 3) whether the severe impairment meets or equals the medical criteria of 20 C.F.R. Part 404 Subpart P, Appendix 1; and 4) whether a claimant can perform her past relevant work based on her RFC. If the claimant cannot perform the tasks required of her prior work, step five of the evaluation requires the ALJ to decide if a claimant can do other work in the national economy in view of her age, education, and work experience. 20 C.F.R. § 404.1520(a). A claimant is entitled to benefits only if unable to perform other work. Bowen v. Yuckert, 482 U.S. 137, 140-42 (1987); 20 C.F.R. § 404.1520(g).

Sequential evaluation—severity screen

Section 404.1520 requires an ALJ to complete the five-step disability inquiry before separately evaluating whether alcoholism materially contributes to disability.

Bustamante v. Larry G. Massanari, Acting Commissioner of the Social Security Administration · filed 2001-08-27(b), (c), (d), (e), and (f)

Here, the ALJ erred by concluding at step two that Bustamante’s “behavioral and emotional conditions” were “the product and consequence of his alcohol abuse and not an independently severe or disabling impairment.” This was improper. The ALJ should have proceeded with the five-step inquiry without attempting to determine the impact of Bustamante’s alcoholism on his other mental impairments. If, and only if, the ALJ found that Busta-mante was disabled under the five-step inquiry, should the ALJ have evaluated whether Bustamante would still be disabled if he stopped using alcohol.

Hernandez v. Margaret M. Heckler, Secretary of Health and Human Services · filed 1983-05-13(b)

Under the Secretary’s systemized procedure for sequentially evaluating a disability claim, the AU first must determine whether the claimant is working, 20 C.F.R. § 404.1520(b) (1982), or whether the claimant does not have a severe impairment, § 404.1520(c). In either case, the claimant is considered not disabled. If, however, an individual’s impairment meets the durational requirement of at least twelve months and is listed in Appendix 1 of the regulations or is determined to be the medical equivalent of a listed impairment, the claimant is considered disabled. § 404.-1520(d). Section 404.1526(a) comes into play here by indicating how “medical equivalence” is determined. If a finding of disability vel non cannot be determined by these three steps, but the claimant does have a severe impairment, the ALJ then must evaluate the claimant’s “residual functional capacity,” age, education, and work experience to determine whether the claimant can do other work. § 404.1520(e), (f).

Pursuant to the Act, the Secretary established Social Security Administration Regulation No. 4. Said Regulation provides for a set order to evaluate disability (20 C.R.F. § 404.1520(a)). In addition, a claimant’s impairment must meet the 12-month duration requirement before being found disabling. If it is determined that a claimant is or is not disabled at any point in the review, further review is not necessary. 20 C.F.R. § 404.1520(a). In following the set order, the AU concluded that a decision on whether the claimant is disabled cannot be made based on work activity (the first step in the sequence). He did, however, use the second step to determine whether the claimant was disabled. Under this second step (20 C.F.R. § 404.1520(c)) if the impairment is not severe, a finding must be made that the individual is not disabled, regardless of age, education and work experience. To have a severe impairment the impairment or combination of impairments must significantly limit the claimant’s physical or mental ability to do basic work activities.

If the claimant meets this burden, then the Secretary has the burden of showing that there is work available in the national economy which the claimant could do. Id. at 1253. The Appeals Council found that from June 19, 1980 until June 7, 1982, Mrs. Dixon was capable of doing her past work. This constituted a finding under 20 CFR § 404.1520(e) that Mrs. Dixon had not made out a prima facie case of a disability. ... AU Walsh found, pursuant to 20 CFR § 404.1520(f), that there were “not a significant number of jobs in the national economy which [Mrs. Dixon] could perform” (tr. 307) during the June 19, 1980 to June 7, 1982 period. We find that substantial evidence supports this conclusion, since both vocational experts testified that if Mrs. Dixon were subject to a severe impairment of her upper extremities, then she would not be able to perform most, if not all, similar jobs available in the economy.

Section 404.1520 establishes a five-step sequential process for evaluating disability claims, including whether an impairment meets or equals a listed impairment and whether the claimant can perform past relevant work.

Richard MATULLO, Appellant, v. Otis R. BOWEN, Secretary · filed 1990-11-26(d) and (e)

The Secretary’s regulations provide a 5 step sequential evaluation process for determining whether or not a claimant is under a disability. 20 C.F.R. § 404.1520. Step 1 states that an individual who is working will not be found to be disabled regardless of medical findings. 20 C.F.R. § 404.1520(b). Step 2 involves evaluating severe impairments. 20 C.F.R. § 404.1520(c). Step 3 requires determining whether the claimant has an impairment or impairments which meets or equals a listed impairment in Appendix 1. 20 C.F.R. § 404.1520(d). Step 4 states that if an individual is capable of performing past relevant work, he will not be found to be disabled. 20 C.F.R. § 404.1520(e). Step 5 requires that if an individual cannot perform past relevant work, other factors must be considered to determine if other work in the national economy can be performed. 20 C.F.R. § 404.1520(f).

Section 404.1520 requires a sequential disability evaluation, and at the other-work step places on the Secretary the burden of showing that the claimant can perform work compatible with his age, experience, education, and physical capacity.

Pence v. Louis Sullivan, Department of Health and Human Services · filed 1992-10-07(f)

The claimant has the ultimate burden of establishing an entitlement to benefits by demonstrating a disability as defined in 42 U.S.C. § 423(d)(1)(A). Disability benefits must be denied to a claimant if he is employed. On the other hand, in the event that the claimant does not have an impairment which significantly limits his ability to work, he is not disabled and his request for benefits must be rejected. However, where a claimant is not working and has a severe impairment, an examination must be conducted to determine whether the impairment satisfies the severity criteria. If the claimed impairment does satisfy one of the itemized severity criteria, the application for benefits will be granted. However, should the claimed impairment fail to satisfy the list of severity criteria, the Secretary must seek to determine if the claimant can return to his previously held job. 20 CFR § 404.1520 et seq.; See Mullis v. Bowen, 861 F.2d 991 (6th Cir.1988). At this point, it becomes the Secretary's burden to show that the claimant can perform other work, taking into account his age, experience, education, physical capacity, and the existence of jobs to match those qualifications. 20 CFR § 404.1520(f).

Under the regulations as promulgated by the Commissioner, a five (5) step sequential procedure must be followed when evaluating a disability claim. 20 C.F.R. §§ 404.1520(a) and 416.920(a). In the sequential evaluation, the Commissioner must consider in order: (1) whether a claimant is gainfully employed, 20 C.F.R. §§ 404.1520(b) and 416.920(b); (2) whether claimant has a severe impairment which significantly limits her ability to perform basic work-related functions, 20 C.F.R. §§ 404.1520(c) and 416.920(c); (3) whether claimant’s impairments meet the Listing of Impairments, 20 C.F.R. §§ 404.1520(d) and 416.920(d); (4) whether claimant can perform her past relevant work, 20 C.F.R. §§ 404.1520(e) and 416.920(e); and (5) whether claimant is disabled in light of age, education, and residual functional capacity, 20 C.F.R. §§ 404.1520(f) and 416.920(f). If, at any step in the sequence, a claimant can be found disabled or not disabled, the sequential evaluation ceases and further inquiry ends. 20 C.F.R. §§ 404.1520(a) and 416.920(a). ... Based on this testimony, and the fact that the term “fair,” as defined by the medical assessment form, clearly implies an unsatisfactory ability, the undersigned finds that the Commissioner has failed to satisfy step five (5) of the sequential evaluation and that Plaintiff is disabled.

Regulations promulgated by the Commissioner establish a five-step analysis to determine disability. 20 C.F.R. § 404.1520 (2003). If the claimant is employed during the period in question, a finding of non-disability is made, and the inquiry ends. 20 C.F.R. § 404.1520(b). At step two, a determination is made whether the claimant suffers from a severe impairment or combination of impairments; if no severe impairment is found, the claimant is deemed not disabled. 20 C.F.R. § 404.1520(c). If step three is reached, a comparison is made between the claimant’s impairments and those listed in 20 C.F.R. § 404, Subpart P, Appendix 1(2003). If the impairment meets or equals those contained in the listing, disability is presumed and benefits are awarded. 20 C.F.R. § 404.1520(d). The fourth step involves a determination as to whether the impairment prevents the claimant from performing past relevant work. ...

Costa v. Astrue · filed 2008-07-17(f)

In evaluating a disability claim, an ALJ is required to follow the sequential step analysis prescribed by 20 C.F.R. § 404.1520. The ALJ must first determine whether a claimant was gainfully employed prior to the onset of the disabling condition. The ALJ must then determine whether the claimant suffers from a severe impairment limiting her ability to work. If the impairment is the same as, or equal in its effect to, an impairment (or combination of impairments) listed in Appendix 1 of Subpart P of the regulations, the claimant is presumptively deemed disabled. If the impairment is not covered by Appendix 1, the fourth step of the analysis requires that the claimant prove that her disability is sufficiently serious to preclude a return to her former occupation. ... Only if she meets that burden is the Commissioner at the fifth step obligated to prove that there are other jobs in the national economy that she could nonetheless perform.

The Commissioner uses a five-step process to evaluate a disability claim. 20 C.F.R. §§ 404.1520(a)(4), 416.920(a)(4) (2010). Pursuant to this process, the Commissioner asks, in sequence, whether the claimant: (1) worked during the alleged period of disability; (2) had a severe impairment; (3) had an impairment that met or equaled the severity of a listed impairment; (4) could return to her past relevant work; and (5) if not, could perform any other work in the national economy. Id. The claimant bears the burden of proof at steps one through four, but the burden shifts to the Commissioner at step five. See Bowen v. Yuckert, 482 U.S. 137, 146 n.5 (1987). If a decision regarding disability can be made at any step of the process, however, the inquiry ceases. See 20 C.F.R. §§ 404.1520(a)(4), 416.920(a)(4). ...

Section 404.1520 requires a five-step sequential evaluation of disability claims, including whether the claimant has a qualifying impairment at step three and can perform other work at step five.

Lester v. Saul · filed 2019-09-25(a)(4)(iii), (g)

The ALJ uses a five-step sequential process in evaluating disability claims. See id. §§ 404.1520(a)-(g). If at any point of this process the ALJ determines conclusively that a claimant is or is not disabled, review does not proceed to the next step. Id. § 404.1520(a)(4). The five steps include evaluations of whether a claimant i) is working; ii) has a severe impairment; iii) has an impairment that meets or equals the impairments in Appendix 1 to Subpart P of the Administrative Regulations No. 4; iv) can return to her past relevant work; and v) if not, whether she can perform other work. See id. §§ 404.1520(a)-(g). If the process reaches the fifth inquiry, in order to show that claimant can perform other work, the ALJ must show both A) that claimant, considering claimant’s age, education, work experience, skills, and physical shortcomings, has the capacity to perform an alternative job, and B) that this alternative job exists in significant numbers in the national economy.

Section 404.1520 establishes a five-step disability evaluation in which Step 2 is a threshold inquiry and the ALJ must continue if any severe impairment is found, while considering all impairments together at Step 4.

Roddy v. Commissioner of Social Security · filed 2020-03-11

To determine whether a plaintiff is disabled, the ALJ considers the following five questions in order: (1) Is the plaintiff presently unemployed? (2) Does the plaintiff have a severe impairment? (3) Does the impairment meet or medically equal one of a list of specific impairments enumerated in the regulations? (4) Is the plaintiff unable to perform his former occupation? and (5) Is the plaintiff unable to perform any other work? 20 C.F.R. § 404.1520. ... The failure to designate depression as a severe impairment, by itself, is not an error requiring remand. At Step 2 of the sequential analysis, the ALJ must determine whether the claimant has one or more severe impairments. This is only a “threshold issue,” and, as long as the ALJ finds at least one severe impairment, she must continue on with the analysis. And, at Step 4, she must consider the combined effect of all impairments, severe and non-severe. Therefore, a failure to designate a particular impairment as “severe” at Step 2 does not matter to the outcome of the case as long as the ALJ finds that the claimant has at least one severe impairment.

Barron v. Commissioner of Social Security · filed 2020-03-18(a), (e)

In order to determine whether the plaintiff is suffering from a disability, the ALJ must employ a five-step inquiry: (1) whether the plaintiff is currently working; (2) whether the plaintiff suffers from a severe impairment; (3) whether the impairment is listed in Appendix 1 of the relevant regulations; (4) whether the impairment prevents the plaintiff from continuing past relevant work; and (5) whether the impairment prevents the plaintiff from doing any kind of work. 20 C.F.R. §§ 404.1520 & 416.920; Berry, supra, 675 F.2d at 467. If a plaintiff is found to be either disabled or not disabled at any step in this sequential inquiry, the ALJ’s review ends. 20 C.F.R. §§ 404.1520(a) & 416.920(a); Musgrave v. Sullivan, 966 F.2d 1371, 1374 (10th Cir. 1992). ...

Section 404.1520 requires disability claims to be evaluated sequentially, with a severe-impairment determination at step two before listing-level evaluation at step three.

Newman v. Saul · filed 2020-07-17(a)(4)(ii), (a)(4)(iii)

The Commissioner has the better argument on this point, even were Newman’s Somatic Disorder to clear the “severe” threshold. The Commissioner is correct that for the hearing officer to consider a diagnosis at the listing, he would first have to find a “severe impairment” at the second step of the sequential evaluation. See 20 C.F.R. § 404.1520(a)(4)(iii). The “severe impairment” requirement is a “de minimis policy, designed to do no more than screen out groundless claims.” ... Similarly, the evidence that Newman’s Somatic Symptom Disorder was linked with increased pain and the exacerbation of her other psychiatric impairments clears the low bar for severity. R. 556, 580, 777, 860. The fact that the hearing officer did not find a severe impairment at step two is therefore an error.

Social Security regulations implement a five-step sequential process to evaluate a disability claim. 20 C.F.R. §§ 404.1520, 416.920; Williams v. Bowen, 844 F.2d 748, 750-51 (10th Cir. 1988) (explaining five steps and burden shifting process). To determine whether a claimant is disabled, the Commissioner inquires: (1) whether the claimant is currently working; (2) whether the claimant suffers from a severe impairment or combination of impairments; (3) whether the impairment meets an impairment listed in Appendix 1 of the relevant regulation; (4) considering the Commissioner’s assessment of the claimant’s residual functioning capacity (“RFC”), whether the impairment prevents the claimant from continuing her past relevant work; and (5) considering assessment of the RFC and other factors, whether the claimant can perform other types of work existing in significant numbers in the national economy. 20 C.F.R. §§ 404.1520(a)(4)(i)-(v), 416.920(a)(4)(i)-(v).

Section 404.1520 establishes a five-step disability evaluation, and omitting an impairment as severe at step two is not ordinarily reversible error when the ALJ considers all impairments in determining residual functional capacity at step four.

Hall v. Commissioner of Social Security · filed 2022-11-10(c), (a)(4)(iv)

At step two of the sequential evaluation process, an ALJ decides whether the claimant has a “severe impairment” or combination of impairments that “significantly limits [the claimant’s] physical or mental ability to do basic work activities[.]” 20 C.F.R. §§ 404.1520(c), 416.920(c); SSR 85-28, 1985 WL 56856, at *3 (Jan. 1, 1985). The finding of a severe impairment at step two of the sequential analysis is, however, only a threshold determination; where the ALJ has found at least one severe impairment, the sequential evaluation process will continue and the failure to include other severe impairments is not itself reversible error. Maziarz v. Sec’y of Health & Human Servs., 837 F.2d 240, 244 (6th Cir. 1987). An ALJ who has found at least one severe impairment must also assess at step four of the sequential evaluation how much work the claimant can perform in her lessened capacity. 20 C.F.R. §§ 404.1520(a)(4)(iv), 416.920(a)(4)(iv). In doing so, “the ALJ must consider limitations and restrictions imposed by all of [the claimant’s] impairments, even those that are not severe.” Fisk v. Astrue, 253 F.App’x 580, 583 (6th Cir. 2007) (cleaned up); see also 20 C.F.R. §§ 404.1523, 416.923. Thus, so long as the ALJ considers at step four all of the claimant’s impairments in determining the claimant’s RFC, the ALJ’s failure to find an additional severe impairment at step two of the sequential evaluation does not ordinarily constitute reversible error. Fisk. 253 F. App’x at 583 (cleaned up).

When considering whether a claimant is eligible for benefits, the Secretary uses a five-step inquiry: 1) is the claimant presently unemployed; 2) is the claimant’s impairment or combination of impairments severe; 3) does the impairment meet or exceed any of the list of specific impairments (the grid) that the Secretary acknowledges to be so severe as to preclude substantial gainful.activity;. 4) if the impairment has not been listed by the Secretary as conclusively disabling, is the claimant unable to perform his or her former occupation; and 5) if the claimant cannot perform the past occupation, is the claimant unable to perform other work in the national economy in light of his or her age, education and work experience. A negative conclusion at any step (except for step three) precludes a finding of disability. An affirmative answer at steps one, two or four leads to the next step.

Failure to qualify for disability benefits at the third step of the analysis, based either on the exertional limitations or mental impairment of plaintiff, moreover, does not end the inquiry. Plaintiff argues that the ALJ, at the fifth step of the analysis— determining “whether the claimant retains the residual functional capacity to ... adjust to other work” — failed to account for “subjective and medical evaluations” of mental impairment and pain in reaching his conclusion.

At that fourth step, the administrative law judge first must assess a claimant’s residual functional capacity, which is defined as “the most [a claimant] can still do despite [her physical and mental] limitations.” ... If a claimant’s residual functional capacity allows her to perform her past relevant work, she is not disabled. 20 C.F.R. § 404.1520(a)(4)(iv). ... At the fifth and final step of the sequential analysis to determine whether a claimant for Social Security disability benefits is in fact disabled, the Commissioner must consider whether the claimant’s residual functional capacity, age, education, and work experience would allow the claimant to “make an adjustment to other work” that “exists in significant numbers in the national economy.” 20 C.F.R. §§ 404.1520(a)(4)(v); 404.1560(c)(2).

Section 404.1520 requires a five-step sequential evaluation of disability claims, with review ending when disability or non-disability is found, presumed disability at step three for a matching listing, and a Commissioner showing at step five that the claimant can adjust to other work.

Bolton v. Saul · filed 2020-01-28(a)(4), (a)(4)(iii), (g)

The Commissioner must perform a five-step analysis to determine whether a particular claimant has met his burden of establishing disability. See 20 C.F.R. §§ 404.1520, 416.920; Plummer v. Apfel, 186 F.3d 422, 427-28 (3d Cir. 1999). If the Commissioner makes a finding of disability or non-disability at any point in the sequential process, the Commissioner will not review the claim further. See 20 C.F.R. §§ 404.1520(a)(4), 416.920(a)(4)(i). ... If the claimant’s impairments are severe, at step three, the Commissioner compares the claimant’s impairments to a list of impairments that are presumed severe enough to preclude any gainful work. See id. §§ 404.1520(a)(4)(ii1), 416.920(a)(4 (iii); Plummer, 186 F.3d at 428. When a claimant’s impairment or its equivalent matches a listed impairment, the claimant is presumed disabled. See 20 C.F.R. §§ 404.1520(a)(4)(iii), 416.920(a)(4)(iii). If a claimant’s impairment, either singly or in combination, fails to meet or medically equal any listing, the analysis continues to step four and five. See id. §§ 404.1520(e), 416.920(e). ... If the claimant is unable to return to past relevant work, at step five, the Commissioner must demonstrate that the claimant’s impairments do not preclude him from adjusting to any other available work. See 20 C.F.R. §§ 404.1520(g), 416.920(g) (mandating finding of non- disability when claimant can adjust to other work); Plummer, 186 F.3d at 428.

20 C.F.R. § 404.1520 establishes a five-step process for evaluating disability claims, and an omission at an earlier step may be harmless when the ALJ's RFC analysis clearly considers the relevant impairment.

BERRAN v. COMMISSIONER OF SOCIAL SECURITY · filed 2022-02-23

Adherence to the five-step procedure is important in its own right, It must be remembered, however, that step three is a screening process that permits the ALJ to award benefits in clear cases without further analysis. The ultimate issue is still the claimant’s RFC, i.e., the level of work he or she can perform despite limitations. I will not reverse when it is patently clear that the ALJ gave careful consideration to obesity when arriving at her bottom-line determination of the RFC..

At the third step of the disability evaluation, the ALJ examines whether a claimant’s impairment meets or medically equals the criteria of a Listings impairment. 20 C.F.R. §§ 404.1520(d), 416.920(d). If the impairment meets or medically equals the criteria of a Listing and meets the durational requirement, then the claimant is disabled. Id. § 404.1509.

Section 404.1520(a)(4)(iii)-(v) requires disability adjudicators to evaluate, in sequence, whether the claimant meets a listed impairment, whether the claimant can perform past work based on residual functional capacity, and whether the claimant can adjust to other work available in the national economy.

HIBEN v. KIJAKAZI · filed 2022-11-08(a)(4)(iii)-(v)

At step three ALJs ask whether a claimant has an impairment or combination thereof that meets the criteria for a presumptively disabling impairment. 20 C.F.R. §§ 404.1520(a)(4)(iii), 416.920(a)(4)(iii). If the claimant does not have such an impairment, the ALJ must assess the claimant’s remaining work ability, i.e., his or her residual functional capacity (“RFC”) which is used to determine whether the claimant can return to past work at step four. Id. §§ 404.1520(a)(4)(iv), 416.920(a)(4)(iv). If the claimant cannot return to past work, the ALJ moves to step five and asks whether the claimant’s RFC and other vocational factors permit adjustment to other work that is adequately available in the national economy. Id. §§ 404.1520(a)(4)(v), 416.920(a)(4)(v). At this final step, “the Commissioner bears the burden of establishing the existence of other available work that the claimant is capable of performing.”

Section 404.1520 treats a listed impairment as grounds for an automatic disability finding; an impairment that is not listed may still be severe and prevent past work.

Boscher v. Heckler · filed 1984-03-28(d)

However, the fact that the claimant’s impairment is not included in the list in Appendix 1 to the regulations does not mean that plaintiff does not suffer from a severe impairment or that plaintiff is able to return to her former employment. The list of impairments which is considered in the third step of the five-step process is merely a short-cut by which disability is automatically found upon a showing that the claimant suffers from a listed impairment.

Sequential evaluation—RFC assessment

Section 404.1520(e) requires evaluation of a claimant's residual functional capacity and past-work demands before deciding whether the claimant can return to past work, while § 404.1520(f) requires consideration of other national-economy work only if the claimant cannot perform past relevant work.

Mitchell v. Schweiker · filed 1982-12-07(e), (f)

It is imperative that an ALJ strictly adhere to the “orderly and uniform framework for analysis and decision of disability claims” which fixes the sequence of decision-making that ALJs are required to follow. ... In order to determine whether a claimant can perform past work, the AU is required to review the claimant’s residual functional capacity (RFC) and the physical and mental demands of the work claimant did in the past. If the ALJ then determines that the claimant can still do this type of work, a finding of not disabled is warranted. 20 C.F.R. § 404.1520(e). ... If the ALJ determines that the claimant cannot perform relevant past work, the ALJ must then move on to the next step which is to determine whether the claimant’s impairment prevents her from performing any other work. At that point it is necessary to consider the claimant’s RFC, age, education, and past work experience to determine if the claimant can perform any other work in the national economy. 20 C.F.R. § 404.1520(f). It is not necessary to consider this step unless the ALJ determines that the claimant cannot return to her past employment.

The regulations provide that where both types of impairments are present, and a finding of disabled under the rules [20 C.F.R. §§ 404.1520(d) and 416.-920(d) ] cannot be made on strength (exertional) limitations alone, the rules reflecting the individual’s maximum residual strength capabilities, age, education, and work experience provide a framework for consideration of the extent of further diminution in the individual’s work capabilities via the non-exertional limitations.

At step four, the Commissioner considers whether the claimant is still able to perform his or her past relevant work. If the claimant can perform past relevant work, the claim is automatically terminated. If the claimant cannot do any past relevant work, the analysis proceeds to the fifth and final step. In that step, the Commissioner considers whether the claimant has the residual capacity to do any other work. If the claimant cannot do any work in light of his or her age, education, and work experience, the Commissioner will determine that the claimant is disabled.
