Can Med Spas and Wellness Spas Accept HSA or FSA? (2026)

Which med spa services can carry a letter (IV, cryo, red light, weight loss) and which never will, why the card fails, and how to offer it for $100 a month.

7 minute read

Burst guide cover, for merchants: the headline "HSA and FSA at your med spa" over the line "Medical services yes, cosmetic no, offered with no POS change" with three tags: By service, Receipt rules, No integration.

Short answer

Yes, for the part of your menu that treats a diagnosed condition, and no for the part that is cosmetic. IV therapy for a documented deficiency, cryotherapy and red light for pain and recovery, massage for chronic back pain, a medical weight loss program run by a prescriber, infrared sauna for a named condition: all of these can carry a letter of medical necessity and be reimbursed from a client's FSA, HSA, or HRA. Botox, fillers, facials, laser hair removal, and body contouring cannot, no matter who writes the letter. The HSA card almost never works at a spa's front desk, so the path that works is a letter, normal payment, and reimbursement, and you can offer it through Burst for $100 a month with no integration.

Which spa services can carry a letter, and which never will?

The dividing line is whether the service treats a condition a clinician has diagnosed or improves how someone looks or feels in general, and IRS Publication 502 puts cosmetic procedures and general-wellness weight loss on the wrong side of it. The table covers the services a wellness or med spa sells most, with 2026 price ranges reported nationally.

Varies

No

Cosmetic procedures are excluded regardless of documentation

A useful test for anything not on the table: would a clinician name a diagnosis and explain how this service treats it in one sentence? If yes, it can carry a letter. If the honest sentence is about glow, energy, or confidence, it cannot.

Why doesn't the HSA card work at my front desk?

Your business is coded as a spa or salon, and the card networks only approve HSA and FSA card charges at merchants coded as medical providers or at retailers that verify each item in real time, so the card declines even when the ticket is a drip a clinician recommended. Mixed tickets make it worse: a facial and an IV on one ticket means the whole charge is declined, and a membership that drafts monthly would need that real-time check to pass every single month. Some spas with a medical director report the card clearing for prescribed services now and then, and declining the next visit. Reimbursement works every time, because it happens after the payment and on the client's side.

What are the options for a spa?

A spa has the same three options a gym or a retailer has, and only one of them was designed for a business that sells at a front desk and a treatment chair.

Option

Getting live

Cost to you

Memberships and packages

Take the card at the desk

Recode as a medical merchant and verify every charge, every visit

Not realistic for a spa with a mixed menu

Declines on mixed tickets and monthly drafts

Truemed or Flex

Sales call, then checkout integration, typically weeks

Not public; typically a rev share

Limited support

Burst

Self-serve, live in 30 minutes, no integration

$100/month, month to month, no contract; $20 one-time letter fee per client, paid by the client or by you

Works with your existing booking and billing; nothing changes

Truemed and Flex are built around online checkout and a partner marketplace, and a few spas do list them. Burst does not care whether you run Boulevard, Vagaro, Zenoti, or a card reader at the desk. The client pays you as usual, a licensed clinician reviews their case, the letter is emailed (usually the same day), Burst files the reimbursement claim, and the client's plan pays them out of their account. If no letter is issued or the plan denies the claim, the $20 refunds automatically.

What needs to be on the receipt?

The receipt has to name the medical service in plain words, with the client's name, the date, your business name, and the amount, and cosmetic items have to sit on a separate ticket. "IV therapy, Myers cocktail, 60 min" reimburses. "Glow Package" does not, even if the package was mostly a drip, because the reviewer at the plan cannot see what was medical. The same goes for memberships: if a client buys a monthly plan that includes two cryo sessions and a facial, bill the cryo as its own line or its own membership. Spas lose more claims to bundled receipts than to anything else, and it is the one part of this you control completely.

What do I tell clients?

One sentence at the desk and one on the booking page is enough. At the desk: "If you have an FSA or HSA, some of our services may be reimbursable with a letter of medical necessity. We work with Burst; a licensed clinician reviews your case, and if a letter fits, Burst files the claim for you. It's $20 one time, refunded if it doesn't go through." On the website, next to the medical services rather than the cosmetic ones: "May be reimbursable from your FSA or HSA with a letter of medical necessity. Ask us how."

Next to those services, "may be reimbursable with a letter of medical necessity" is the accurate line, since the client's plan decides each claim, and it keeps the cosmetic side of your menu from inviting claims that will be denied.

How to offer this at your spa

  1. Sign up at getburst.com/self-serve. Self-serve setup takes about 30 minutes, and nothing about your booking, billing, or POS changes.

  2. Decide whether clients pay the $20 one-time letter fee or you cover it as a perk on medical services.

  3. Split your menu and receipts so medical services are itemized on their own, and add the one-line note next to those services on your booking page.

  4. Give the front desk the script above and the link. Clients enroll, get their letters before they pay, and Burst files their claims. Your cost is $100 a month, no contract.

Frequently asked questions

Can clients use HSA or FSA for Botox or fillers?

No. Cosmetic procedures are excluded, and a letter does not change that. The exception in the rules is reconstructive work after an injury, illness, or congenital condition, which is not what a med spa menu sells.

Do I need a medical director to offer this?

Not for the letter side; Burst's licensed clinicians write the letters and Burst files the claims. Services that already require a prescriber, like semaglutide or hormone therapy, still need your prescriber exactly as they do today.

Can I just take the HSA card for my medical weight loss program?

Sometimes the card clears for a prescribed program and sometimes it declines, most often on a mixed ticket or a monthly draft. Reimbursement with a letter is the path that works on every visit.

A client bought a 10-drip package last month. Can they claim it now?

No. The letter has to be dated on or before the purchase, for every provider. Introduce the link before the package is sold, not after.

What does Burst cost compared with Truemed or Flex?

Burst is $100 a month, month to month, no contract, plus a $20 one-time letter fee per client that you or the client pays. Truemed and Flex do not publish merchant pricing; terms come through their sales process and typically include a rev share.

Is the letter a guarantee the client gets paid back?

No. The client's plan administrator decides every claim under its own rules. The letter gives the reviewer the medical reason, Burst files the claim, and if the plan says no, the $20 letter fee is refunded to whoever paid it.
