Is a 'continuous passive motion' (CPM) device an exempt orthopedic device or a taxable therapeutic appliance under Texas sales tax rules, and when is it exempt when sold, leased, or rented?

Plain-English summary

This letter has two parts. The 1992 follow-up letter (dated June 22, 1992) responds to a taxpayer's request that the Comptroller reconsider earlier rulings that had classified a "continuous passive motion device" (CPM) as a therapeutic appliance/device. Based on new facts showing the device works on joints, not muscles, the Comptroller reclassified the CPM device as an orthopedic device under Rule 3.284(a)(9), which defines an orthopedic device as any appliance or device designed specifically for correcting or preventing human deformities, defects, or chronic diseases of the skeleton, joints, or spine. The letter also clarifies that a CPM device does not qualify as a "brace," because it isn't designed to provide rigidity or support — its purpose is forced, regulated joint movement.

The letter reprints the original April 20, 1992 ruling it is reconsidering. That original ruling held that a CPM device qualifies as a therapeutic appliance or device and is exempt from Texas sales or use tax when sold, leased, or rented to individuals under a licensed practitioner's prescription. It is taxable when sold to a doctor's office, clinic, hospital, nursing home, or other institution — unless that purchasing institution itself qualifies for a religious, charitable, or educational exemption (or an exemption under Internal Revenue Code sections 501(c)(3), (4), (8), (10), or (19)). No exemption certificate is required for a sale, lease, or rental made to an individual under a doctor's prescription, but an exempt institution must issue an exemption certificate in lieu of paying tax.

What this means for you

Medical equipment sellers, lessors, and rental companies

If you sell, lease, or rent CPM devices, the tax treatment of the transaction depends on who the buyer is, not on whether the device is labeled "orthopedic" or "therapeutic." A sale, lease, or rental to an individual under a doctor's prescription is exempt and doesn't require an exemption certificate. A sale to a clinic, hospital, doctor's office, or nursing home is taxable unless that institution independently qualifies for a religious, charitable, or educational exemption — in which case it must give you an exemption certificate.

Physical therapy providers and orthopedic practices

The letter confirms a CPM device is treated as an orthopedic device (not a brace) because it produces forced, regulated joint movement rather than providing rigid support. This classification only applies based on the facts presented in this specific case — if your equipment works differently (e.g., it primarily affects muscles rather than joints, or actually provides bracing/support), the classification could come out differently.

Patients and their prescribing practitioners

If you are prescribed a CPM device by a licensed practitioner of the healing arts, the sale, lease, or rental to you personally is exempt from Texas sales or use tax, and no exemption certificate paperwork is needed on your end.

Accountants and tax professionals

This is a useful illustration of how the Comptroller can revisit and reclassify a device's tax category when a taxpayer supplies additional or different facts — here, shifting from "therapeutic appliance" to "orthopedic device" changed which underlying rule governs, even though the exemption's ultimate structure (exempt to prescribed individuals, taxable to institutions absent their own exemption) stayed the same.

Common questions

Q: Is a CPM device taxable or exempt in Texas?
A: It depends on the buyer. It's exempt from Texas sales or use tax when sold, leased, or rented to an individual under a licensed practitioner's prescription. It's taxable when sold to a doctor's office, clinic, hospital, nursing home, or other institution, unless that institution itself qualifies for a religious, charitable, or educational tax exemption.

Q: Why did the Comptroller reclassify the CPM device from "therapeutic appliance" to "orthopedic device"?
A: The earlier ruling was based on information indicating the device worked on muscles. The taxpayer's later letter presented facts showing the device instead works on joints, which meets the Rule 3.284(a)(9) definition of an orthopedic device (an appliance for correcting or preventing deformities, defects, or chronic diseases of the skeleton, joints, or spine).

Q: Does a CPM device qualify as a "brace"?
A: No. The letter states there was no indication the device was designed or used to provide rigidity or support like a brace; its intended purpose is forced, regulated joint movement.

Q: Do I need an exemption certificate to sell, lease, or rent a CPM device to a patient with a prescription?
A: No. An exemption certificate is not required when the item is sold, leased, or rented to an individual under a doctor's prescription. An exemption certificate is required, though, when an exempt organization (religious, charitable, educational, or a qualifying 501(c) organization) is the purchaser.

Q: Can I rely on this letter for my own CPM device or equipment?
A: No. Both letters state the opinion is based on the facts presented, and different, though similar, facts might lead to a different answer. STAR letters can support a detrimental-reliance claim only for the taxpayer to whom the letter was directly issued.

Original ruling text

June 22, 1992

Dear **:

This is in response to your letter dated April 24, 1992, asking this office to
reconsider previous rulings that have categorized a "continuous passive motion
device" (CPM) as a therapeutic device.

You have presented additional facts and information that indicate a "continuous
passive motion device" should be classified as an orthopedic device rather than
a therapeutic device.

Rulings are based on the facts as presented. Information previously submitted
to this office that resulted in our ruling that a "CPM" device met the
definition of a therapeutic appliance or device indicated that a "CPM" device
worked on muscles, not on joints.

Information presented in your letter indicates the opposite; that the device is
designed to work on joints rather than muscles. Rule 3.284(a)(9) defines an
orthopedic device as any appliance or device designed specifically for use in
the correction or prevention of human deformities, defects, or chronic diseases
of the skeleton, joints, or spine. Based on the additional information that you
have provided, the "CPM" device qualifies as an orthopedic device.

You also asked for an opinion as to whether or not a "CPM" device qualified as
a brace. Information I have reviewed does not indicate that a "CPM" device was
designed or is used for the purpose of providing rigidity or support (as a
brace). The intended purpose of a "CPM" device appears to be forced, regulated
joint movement.

This opinion is based on the facts presented. Different facts, though similar,
might lead to different answers. If you have any questions, feel free to write
or call me at 1-800-531-5441, extension 5-0330, or 512/463-4600.

Dear **:

Thank you for your letter requesting an opinion regarding the taxability of a
"continuous passive motion device" (CPM).

The "continuous passive motion device" (CPM) qualifies as a therapeutic
appliance or device and is exempt from Texas sales or use taxes when sold,
leased, or rented to individuals under a prescription of a licensed
practitioner of the healing arts. The device is taxable when sold to a doctor's
office, clinic, hospital, nursing home, or other institutions; unless, that
purchaser qualifies for exemption from Texas taxes as a religious, charitable,
educational organization or as an organization qualifying for Internal Revenue
Code exemptions 501(c) (3), (4), (8), (10), or (19).

An exemption certificate is not required when the item is sold, leased, or
rented to an individual under a doctor's prescription. However, an organization
qualifying for the above-referenced exemptions must issue an exemption
certificate in lieu of the tax.

I am enclosing rules on medical equipment, exempt organizations, and exemption
certificates for your review.

This opinion is based on the facts presented. Different facts, though similar,
might lead to different answers. If you have any questions, feel free to write
or call me at 1-800-531-5441, extension 5-0330, or 512/463-4600.
