A $349 Hypervolt 3 Pro is HSA eligible for one buyer and not for the next.
A massage gun qualifies when it treats a specific diagnosed condition. It does not qualify when you buy it for general soreness after workouts. The device is identical either way. What changes is the documentation behind it.
Tripl is not a tax advisor or a medical provider. Eligibility depends on your situation.
The Short Answer
| Situation | HSA eligible? |
|---|---|
| General muscle soreness, workout recovery, "wellness" | No |
| Diagnosed condition, backed by a Letter of Medical Necessity | Yes |
| Recommended by a clinician as part of a treatment plan | Yes, keep the paperwork |
| Bought with an HSA card because the store accepted it | Not automatically |
That last row is the one people get wrong.
The Rule Under IRC 213(d)
Section 213(d)(1)(A) defines medical care. It covers amounts paid "for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for the purpose of affecting any structure or function of the body."
IRS Publication 502 draws the other edge. Medical expenses "don't include expenses that are merely beneficial to general health, such as vitamins or a vacation."
A Theragun on sore quads after a 10K is general health. A Theragun recommended by a physician for diagnosed fibromyalgia is treatment. Same $219.99 device.
This is the same test we walk through in Can You Use Your HSA for a Gym Membership?. Percussion devices are not a special case. They are a standard gray-zone item.
What the Letter Has to Say
An LMN is a signed statement from a licensed clinician. It ties one specific product to one specific diagnosis.
Our guide Letter of Medical Necessity (LMN): What It Is and How to Get One covers the process. Five elements it needs:
- ●Patient name and date of birth
- ●The specific diagnosis, with the ICD-10 code when available
- ●The device named exactly. "Theragun Mini" beats "massage device"
- ●How long the recommendation stays valid
- ●Provider name, credentials, license number, signature, and date
Flex names musculoskeletal conditions among those an LMN can rest on. Chronic back pain, sciatica, fibromyalgia, plantar fasciitis, and post-surgical rehab all sit in that group.
A trainer or health coach cannot write it. The provider has to be licensed to diagnose.
Buying Direct From Therabody
Verified on therabody.com in September 2026.
Therabody runs HSA/FSA checkout through Flex. Their page says: "At checkout, select 'Flex | Pay with HSA/FSA' as your payment option, enter your HSA or FSA debit card, and complete your checkout as usual."
Not everything in the catalog qualifies. Therabody tells you to "look for the HSA/FSA Accepted tag when browsing our devices."
Flex handles the substantiation. Some products trigger a short chat-based telehealth consult during checkout. A licensed clinician reviews your answers and issues an LMN when they support one.
Pay with a credit card instead and Flex emails an itemized receipt. You submit that to your plan for reimbursement.
Listed prices at publication: Theragun Mini $219.99, Theragun PRO Plus $649.99.
Buying Direct From Hyperice
Verified on hyperice.com in September 2026.
Hyperice is simpler at the register. Their page says: "Simply select 'Pay with your FSA or HSA card' at the payment option of checkout and use your FSA or HSA card as you would any other credit card."
No survey on the brand's own site. No letter issued at checkout. The order confirmation is your receipt.
Hypervolt models tagged FSA/HSA eligible: Go 3 at $149, Hypervolt 3 at $249, Hypervolt 3 Pro at $349.
That convenience has a catch. Nobody asked you any questions, so nobody built your substantiation file. If your plan or the IRS asks later, the letter is on you.
Truemed Is Still the Mechanism Elsewhere
Truemed is the third-party service behind a lot of HSA/FSA checkouts. You complete a short health survey at checkout. An independent licensed clinician reviews it and issues an LMN if you qualify.
Truemed's own language is worth reading. "Qualification isn't guaranteed for every customer or every purchase."
These flows shift. Oura dropped Truemed from its store between June and September 2026. Our post Is the Oura Ring HSA or FSA Eligible? Yes. Here’s How covers that change.

Retailer vs Brand Direct
| Where you buy | What you get | What is missing |
|---|---|---|
| Brand site (Therabody, Hyperice) | HSA/FSA payment option, itemized receipt | The letter, unless the flow issues one |
| Online marketplace HSA/FSA section | Card payment and an eligibility flag | No clinician review, no letter |
| Big-box or sporting goods | A generic receipt | Almost everything |
| Any store, rewards card, reimburse later | Full control of the paper trail | Nothing, if you keep the receipt |
Brand-direct is the cleanest path. The itemized receipt names the product. A big-box receipt that reads "electronics" does not help you at audit.
The reimburse-later route works anywhere. Pay with a rewards credit card. Keep the itemized receipt and the letter.
Reimburse from the HSA whenever you want, even years later. That play is one of three in When to Reimburse Yourself From Your HSA: 3 Strategies Compared.
Card Acceptance Is Not IRS Approval
An HSA card clearing at checkout is not an IRS ruling.
Card acceptance is a merchant category code plus a retailer's eligibility list. Neither one is the IRS. Neither one is your plan administrator's audit desk. The burden of proof stays with you.
A non-qualified distribution gets ugly fast. Income tax on the full amount, plus a 20% penalty. Pub 969 drops that penalty only for distributions "made after the date you are disabled, reach age 65, or die."
On a $349 Hypervolt 3 Pro in a 24% bracket, that runs about $154. The letter costs one telehealth visit.
Devices Are Not the Same as Massage Therapy
Two different questions with two different answers.
A massage gun is equipment. You buy it once, and the letter covers that purchase.
Massage therapy is a service from a licensed therapist. It also needs an LMN, but the letter covers a course of visits. Spa massages do not qualify either way.
The rule is in Can You Use Your HSA for Massage Therapy? Here Is the Rule.
What to Keep on File
- ●The itemized receipt showing product name, date, and amount
- ●The LMN, signed and dated, naming the condition and the device
- ●The order confirmation email if you bought online
- ●A note of which expenses that letter covers
Tripl stores the LMN as a supporting document and links it to the purchase it backs. One letter can cover several expenses. Tripl tracks the expiration date and flags anything outside the window. At tax time the receipt and the letter land in the same PDF.
The Checklist
- ●Decide honestly whether you have a diagnosed condition. If not, stop here.
- ●Ask your clinician for an LMN naming the specific device.
- ●Buy from the brand site so the receipt is itemized.
- ●Pay with the HSA card, or use a rewards card and reimburse later.
- ●File the receipt and the letter together.
- ●Re-check the brand's checkout flow before you buy. These change.
