CO PLR 21-006 Sales & Use Tax 2021-10-20

Does a Colorado seller charge sales tax on an implantable, single-use diagnostic heart monitor sold to healthcare providers, or is it an exempt medical device?

Short answer: Yes, it's taxable. A single-use heart monitor implanted to diagnose irregular heartbeats is taxable tangible personal property when sold to healthcare providers. It does NOT qualify for Colorado's medical exemptions: it isn't a prosthetic device (it only diagnoses; it doesn't replace, correct, or support a body part), and it isn't durable medical equipment (it's single-use and is implanted in the body). The provider's purchase isn't a tax-free wholesale/resale either, because the provider uses and alters the device by implanting it in a patient.

Plain-English summary

A medical-device company sells a small heart monitor that is temporarily implanted under a patient's skin to record irregular heartbeats. It's single-use, requires a prescription, is purely diagnostic, and can stay implanted from a few days up to three years before a physician reviews the data. The company asked Colorado whether selling it to healthcare providers is taxable. The Department's answer: yes, it's taxable.

The reasoning has two halves. First, is this a taxable retail sale at all, or a tax-free wholesale (resale) sale? The Department said retail — the healthcare provider doesn't buy the monitor to resell it unchanged; the provider uses it and alters it by implanting it in a patient. That's the opposite of buying-for-resale, so it's a retail sale of tangible personal property.

Second, does any medical exemption rescue it? Colorado exempts specific medical devices, but the heart monitor fits none of them:

  • Prosthetic device exemption — no. A prosthetic device replaces, corrects, or supports a portion of the body. The monitor only diagnoses; it doesn't replace, correct, or support anything, so it isn't a prosthetic device.
  • Durable medical equipment (DME) exemption — no. DME must withstand repeated use and must not be worn in or on the body (the rule repeatedly requires it to be "non-implanted"). The monitor is single-use and is implanted, so it fails on two counts.

With no exemption and no resale, the company must collect state and state-administered local sales tax.

What this means for you

Medical-device sellers

Don't assume "prescription + medical purpose" equals exempt. Colorado's medical exemptions are narrowly defined. A device that merely monitors or diagnoses — rather than replacing, correcting, or supporting the body — generally isn't a prosthetic device, and a single-use or implanted item generally isn't durable medical equipment. Map your product to the exact statutory definitions before treating a sale as exempt.

Hospitals, clinics, and other healthcare providers

When you buy a device and consume it in patient care (implanting, applying, using it up), you're the end user, not a reseller — so you can't buy it tax-free for resale, and you'll bear sales/use tax unless a specific device exemption applies. Single-use implantables like this monitor are taxable.

Accountants and tax professionals

The two pivots are the wholesale-vs-retail test (resale must be "in an unaltered condition and basically unused," per A.B. Hirschfeld Press) and the precise device definitions: prosthetic device under 1 CCR 201-4, Rule 39-26-717(1)(c) / § 39-26-717(2)(f), and DME under § 39-26-717(1)(a)(I) / § 39-26-717(2)(j) (note the "can withstand repeated use" and "not worn in or on the body / non-implanted" requirements). Watch the home-rule-city caveat.

Common questions

Q: Is a prescription medical device automatically exempt from Colorado sales tax?
A: No. Requiring a prescription isn't enough. The device must fit a specific exemption category — such as prosthetic device or durable medical equipment — and many diagnostic, single-use, or implanted devices don't qualify.

Q: Why isn't the heart monitor a "prosthetic device"?
A: A prosthetic device replaces, corrects, or supports a portion of the body. This monitor only collects diagnostic data; it doesn't do any of those things, so it falls outside the prosthetic-device exemption.

Q: Why isn't it "durable medical equipment"?
A: DME must be able to withstand repeated use and must not be worn in or on the body (the rule requires it to be non-implanted). The monitor is single-use and is implanted, so it fails both requirements.

Q: Could the provider buy it tax-free for resale?
A: No. To be a tax-free wholesale purchase, the buyer must acquire the item for resale basically unused and unaltered. A provider that implants the device is using and altering it, so the sale is a taxable retail sale.

Q: Can another medical-device company rely on this ruling?
A: No. A private letter ruling binds the Department only for the taxpayer and facts it was issued to, and explicitly cannot be relied on by anyone else. It shows the Department's reasoning, but your device and facts may differ.

Q: Does this cover city tax too?
A: No. The Department administers state and state-administered local sales and use tax only. Self-collected home-rule cities set their own rules and may treat medical devices differently. Check each home-rule city.

Re: Request for private letter ruling to determine whether medical product is exempt from sales
and use tax.
Dear XXXXXXXXXX:
You submitted a request for a private letter ruling on behalf of XXXXXXXXXX (the “Company”),
regarding the taxability of the XXXXXXXXXX heart monitor (the “heart monitor”), to the Colorado
Department of Revenue (“Department”) pursuant to 1 CCR 201-1, Rule 24-35-103.5. This letter
is the Department’s private letter ruling. This ruling is binding on the Department to the extent
set forth in 1 CCR 201-1, Rule 24-35-103.5. It cannot be relied upon by any taxpayer other than
the taxpayer to whom the ruling is made.
Issue
Whether the heart monitor is subject to state and state-administered local sales tax in
Colorado?
Conclusion
The sale of the heart monitor to Colorado customers is subject to state and state-administered
local sales tax in Colorado because the heart monitor is tangible personal property sold by a
retailer and is not exempted from sales tax under the medical devices exemption.
Background1
Company has provided the following statement of facts:
The heart monitor is temporarily implanted under the skin to monitor irregular heartbeats.
This product is single use, and a prescription is required to purchase the device from the
Company. The device is solely diagnostic and can be implanted for a few days or up to

1 This section generally recites the statements of fact set forth in the request as required by paragraph (4)(b)(ii) of 1

CCR 201-1, Rule 24-35-103.5. The recitation of particular facts in this section is not an indication that the
Department found such facts relevant to its analysis. Some relevant facts may be redacted as required by section
24-35-103.5(5), C.R.S. The terms used in this section to describe the factual background are generally those of the
requester.

three years. Once the heart data is collected, the physician reviews the recorded data to
determine further treatment for heart arrhythmia.
For purposes of this private letter ruling, we are assuming the Company is selling heart monitors
only to healthcare providers.
Discussion
The sale of the heart monitor to Colorado customers is a retail sale of tangible personal property
subject to state and state-administered local sales tax in Colorado, unless a specific sales tax
exemption applies. Colorado imposes a sales tax on the retail sale of tangible personal
property.2 Every sale that is not a wholesale sale is a retail sale.3 A wholesale sale is a sale by
a wholesaler to a retailer, jobber, dealer, or other wholesaler for the purpose of resale.4 In order
for a sale to be a wholesale sale, “the primary purpose of the transaction must be the acquisition
of the item for resale in an unaltered condition and basically unused by the purchaser.”5
Based on the statement of facts provided by the Company, the healthcare provider purchases
the heart monitor not for resale, but to treat a patient by implanting the heart monitor for
diagnostic purposes. Because the heart monitor is implanted in a patient, the healthcare
provider appears to be both using the heart monitor and altering its condition. Consequently, the
sale of the heart monitor is not a wholesale sale, and is instead a retail sale.
The heart monitor is tangible personal property under Colorado law. Tangible personal property
is defined as “corporeal personal property. The term embraces all goods, wares, merchandise,
products and commodities, and all tangible or corporeal things and substances that deal in and
capable of being possessed and exchanged . . . .”6 The heart monitor is a product. In addition,
the heart monitor is capable of being possessed and exchanged. Therefore, the heart monitor is
tangible personal property under Colorado law.
A retailer is required to collect sales tax on any retail sale of tangible personal property, except
when such sales qualify for an exemption specifically authorized by law. Colorado exempts
sales of specific types of medical devices from sales tax, such as prosthetic devices and sales
of durable medical equipment.7 The sale of the heart monitor does not qualify for a sales tax
exemption in Colorado.
The heart monitor does not qualify for the prosthetic device sales tax exemption in Colorado. A
prosthetic device is defined by rule as:
“a replacement, corrective, or supportive device, . . . and worn on or in the body to:

2 Section 39-26-104(1)(a), C.R.S.
3 Section 39-26-102(9), C.R.S.
4 Sections 39-26-102(18) and (19), C.R.S.

(i) artificially replace a missing portion of the body;
(ii) prevent or correct physical deformity or malfunction; or
(iii) support a weak or deformed portion of the body.”8
The heart monitor is purchased by a healthcare provider and used as a diagnostic tool to
monitor a patient’s irregular heartbeats. Due to the heart monitor’s diagnostic use, it does not
replace, correct, or support any portion of the body and is, therefore, not a prosthetic device.
Consequently, in accordance with 1 CCR 201-4, Rule 39-26-717(1)(c), the heart monitor is not
exempt from sales tax under section 39-26-717(2)(f), C.R.S.
The heart monitor is also not durable medical equipment. Durable medical equipment is defined
in statute as
“equipment . . . dispensed pursuant to a prescription order, that:
(A) Can withstand repeated use;
(B) Is primarily and customarily used to serve a medical purpose;
(C) Is generally not useful to a person in the absence of illness or injury; and
(D) Is not worn in or on the body.”9
Consistent with the specification that the equipment “is not worn in or on the body,” the related
rule repeatedly specifies that qualifying equipment must be “non-implanted.”10
While the heart monitor is only sold with a prescription order and is used primarily to serve a
medical purpose, monitoring irregular heartbeats, the heart monitor does not qualify as “durable
medical equipment” because it cannot withstand repeated use (Company specifies that the
“product is single use”), and it is implanted in the body. Because the heart monitor does not
meet the definition of “durable medical equipment” the sale of the heart monitor is not exempt
from sales tax under section 39-26-717(2)(j), C.R.S.
Accordingly, without an applicable exemption, the Company is required to collect state and
state-administered local sales tax on the retail sale of the heart monitor.
Miscellaneous
This ruling is premised on the assumption that Company has completely and accurately
disclosed all material facts, that all representations are true and complete, and that Company
has otherwise complied with the requirements of section 24-35-103.5, C.R.S., and the rules
81 CCR 201-4, Rule 39-26-717(1)(c).
9 Section 39-26-717(1)(a)(I), C.R.S. Examples of qualifying durable medical equipment include hospital beds,

intravenous poles and pumps, trapeze bars, toileting aids, bath and shower aids, standing aids, adaptive car seats,
communication devices, and any related accessories for such items. 1 CCR 201-4, Rule 39-26-717(1)(h).
