Four wearables. Four different checkouts. Oura takes the HSA card directly. Whoop routes through Truemed at checkout.
Garmin has you pay normally and file afterward. Apple has no HSA checkout at all.
The IRS rule under all four is the same. Publication 502 excludes anything "merely beneficial to general health." A wearable qualifies when it manages a diagnosed condition, and the paperwork exists to show that.
This is the comparison table, then what each company's own pages say, then the rule.
The Table
As of August 2026, from each company's own pages, plus the IRS rule where a company has no page:
| Oura | Whoop | Garmin | Apple Watch | |
|---|---|---|---|---|
| Pay with HSA card at checkout | Yes, on the Oura store | Yes, via Truemed at join.whoop.com | No. Pay normally, file after | No |
| Letter of Medical Necessity | "Some providers may ask" | Truemed "verifies your eligibility" | Truemed issues one after a same-day survey | Your own doctor, or Truemed's open survey |
| Split payment with a second card | No | Yes, via Truemed | Not applicable | Not applicable |
| What is excluded | Extend protection plans | Purchases outside join.whoop.com | Products not on Garmin's list | No company list. General-health rule excludes bands, AppleCare, cellular, Fitness+ |
| Reimbursement path if the card fails | Pay, then claim with the receipt | Pay, then claim. Provider may require the UPC | The only path | The only path |
Oura
Oura's support page covers the store. Most items, "including taxes and shipping," can be bought with HSA or FSA funds. The card is entered "just like a regular credit or debit card." The store does not support split payments, so the card has to cover the whole order.
Two exclusions. The two-year and three-year Extend Protection Plans are not eligible. And Oura's page says "some providers may ask for a letter from a healthcare professional." Get one if yours does.

Whoop
Whoop's support article was updated June 2026. It lists the membership and the battery packs as eligible through a Truemed checkout at join.whoop.com. Not on shop.whoop.com.
Whoop says Truemed "verifies your eligibility and processes the transaction." Whoop's page also describes a Split Payment option for ineligible items.
You get an order confirmation from Whoop and a receipt from Truemed with an itemized breakdown. Keep both.

Garmin
Garmin's path is reimbursement, not checkout. Its blog says to pay with a normal payment method. Then use the link in the order confirmation to complete Truemed's health assessment "the same day as your purchase."
Truemed says an independent licensed clinician reviews it. Garmin says an approved letter arrives "within a day or two." Claims "are often paid in 2 to 4 weeks."
Garmin lists the eligible lines: fēnix, Forerunner, Instinct, Lily, Venu, vívoactive, vívosmart, plus Tacx trainers and Edge cycling computers.
For an HSA, the claim step is optional. Keep the letter and the receipt. Reimburse yourself.
Apple Watch
As of August 2026, Apple's store and support pages turn up no HSA or FSA option. No Truemed checkout either. Truemed's blog does not name Apple among the brands it lists.
The path is the general one. Truemed's survey is open to anyone, brand partnership or not. A Letter of Medical Necessity from your doctor or from that survey, tying the watch to a diagnosed condition. Then buy with a regular card and reimburse yourself.
Apple's ECG app, on Series 4 or later and all Ultra models, checks for atrial fibrillation. That is the feature a letter would name.

The Rule Under All Four
The tax code defines medical care as amounts paid for "the diagnosis, cure, mitigation, treatment, or prevention of disease." A tracker bought to train harder is general health. A tracker bought on a clinician's recommendation to manage a diagnosed condition is closer to medical care.
The checkout does not decide that. Oura's card acceptance, Whoop's Truemed flow, and Garmin's survey are each company's way of handling the paperwork. None of them is an IRS ruling. The Letter of Medical Necessity, tied to a real diagnosis, is the document that answers the question.
If you have the diagnosis, get the letter regardless of which checkout you use. If you do not, the honest answer is that the purchase is a general-health expense.
What to Keep
- ●The receipt showing the device, the price, and the date.
- ●The Letter of Medical Necessity, if one exists. Truemed says its letters are typically valid for 12 months.
- ●For a membership, the service period. A renewal is a new purchase with a new receipt.
Tripl is an HSA receipt tracker. Forward the order email or upload the receipt PDF. Tripl reads the date, the amount, the category, and the description. Attach the letter to the same expense.
The record is stored in the cloud. Connect Google Drive or Dropbox and it mirrors to your own account too. Two copies, two places.
Tripl is $30 per year for the first 100 sign-ups. After that, $50 a year.
