10 Surprising Things Your HSA or FSA Will Actually Pay For (2026)

I used my FSA card twice last year. Once at the pharmacy for my son's inhaler. Once by accident when I grabbed the wrong card buying coffee.

That was my benefits strategy.

Then my wife forwarded me something from her HR platform — a list of things our FSA would cover. I recognized half of them. Sunscreen. Claritin. The blood pressure cuff I bought for my dad. Period products. Bandages.

I'd been buying all of it with after-tax dollars.

The 30-second cheat sheet

Auto-eligible (no paperwork)

Sunscreen, period products, OTC pain relievers, bandages, thermometers, blood pressure monitors, condoms, breast pumps.

LMN unlocks them (the surprises)

Theragun, Oura Ring, HEPA air purifier, continuous glucose monitor, light therapy lamp, specialty supplements, hypoallergenic bedding, sometimes even a Peloton.

TL;DR: Some surprising items are eligible automatically. Others need a one-page doctor's note (an LMN) that takes minutes to get.

1. Premium sunscreen (Supergoop, La Roche-Posay, etc.)

Any sunscreen with SPF 15 or higher is auto-eligible — no LMN, no paperwork. That includes high-end brands people don't think to put on the HSA. Buy your Supergoop SPF 50 with pre-tax dollars and save 20–30%. Same for tinted SPF moisturizers if they meet the SPF minimum. Caeli flags eligibility right on the Amazon, Target, or brand-direct product page so you don't have to wonder.

2. Theragun and other percussion massage devices

Eligible with an LMN for chronic pain, post-injury recovery, or fibromyalgia. A Theragun Prime+ runs around $300 — about $90 of pre-tax savings if you're in a 30% combined tax bracket. Hyperice, TimTam, and other percussion brands work the same way.

3. Oura Ring and other smart sleep wearables

Eligible with an LMN when used to manage a sleep disorder, anxiety, or another diagnosable condition. The Oura Ring 4 starts around $349. Whoop's subscription model is also commonly LMN-eligible. The 2026 trend: more clinicians comfortable writing LMNs for wearables given their sleep and recovery tracking value.

4. HEPA air purifiers

LMN-eligible for asthma, allergies, COPD, or other respiratory conditions. A Levoit Core 300 runs around $100; high-end models like the Coway Airmega can hit $400+. The LMN is straightforward if you have a documented allergy diagnosis on file with your PCP.

5. Continuous glucose monitors (CGMs)

FDA-cleared CGMs prescribed for diagnosed diabetes are auto-eligible — no LMN needed. Off-label or wellness use (like the Stelo or Lingo CGMs marketed to non-diabetics) generally requires an LMN, ideally tied to insulin resistance or pre-diabetes.

6. Period products

Tampons, pads, menstrual cups, and period underwear have been auto-eligible since the CARES Act in 2020. Almost no one knows this. If you spend $100/year on period products, that's $20–$30 of pre-tax savings you've been missing.

7. Acne treatment and dermatology skincare

OTC acne treatments (benzoyl peroxide, salicylic acid, adapalene) are auto-eligible. Dermatology-prescribed retinoids, prescription tretinoin, and acne kits like Curology are also covered. Cosmetic skincare (anti-aging serums, vitamin C for general glow) is not eligible.

8. Specialty supplements (Thorne, Pure Encapsulations, etc.)

Eligible with an LMN for documented deficiencies — Vitamin D for diagnosed deficiency, B12 for documented anemia, magnesium for sleep disorders, omega-3s for cardiovascular conditions. A general multivitamin for "wellness" is not eligible no matter what. The trick is the diagnosis-to-supplement match.

9. Light therapy devices

LMN-eligible for seasonal affective disorder (SAD), certain skin conditions like psoriasis, and circadian rhythm disorders. Verilux HappyLight, Carex Day-Light Classic Plus — anywhere from $40 to $200, easily covered by HSA/FSA with the right paperwork.

10. Peloton and home gym equipment (yes, sometimes)

This one surprises people. A Peloton or treadmill can be LMN-eligible if your doctor explicitly prescribes regular aerobic exercise to manage a documented condition (cardiovascular disease, hypertension, type 2 diabetes, obesity-related comorbidities). The LMN must connect the equipment to the condition — "I want one for general fitness" doesn't fly. Plan administrators are stricter on this category, so a templated, well-sourced LMN matters.

Caeli shows an instant eligibility badge on every product page across Amazon, Target, CVS, and thousands more, so you know before you buy. And if something needs an LMN, the integrated telehealth flow handles it at checkout in minutes. Install Caeli and start shopping with your benefits, not around them.

Frequently asked questions

Are luxury sunscreens like Supergoop really HSA-eligible?

Yes. The IRS doesn't price-discriminate on sunscreen. As long as it has SPF 15 or higher and is intended for sun protection (not as a tinted moisturizer with a side of SPF), it's eligible — whether it's $8 drugstore or $42 Supergoop.

Can I use my HSA for an Oura Ring without a sleep disorder diagnosis?

Generally no — the Oura Ring (and most smart wearables) needs an LMN tied to a documented condition. Sleep disorders, anxiety, atrial fibrillation, and certain cardiovascular conditions are the most common qualifying diagnoses. If you don't have one of those, the LMN won't pass administrator review.

How do I get an LMN for a Theragun or Peloton?

Three options: (1) ask your existing PCP at your next visit, free. (2) Use a specialty telehealth service — $20 to $75, 24 to 48 hours. (3) Use Caeli's integrated telehealth flow at checkout. The LMN must tie the specific equipment to a specific diagnosed condition.

Are tampons and period products HSA-eligible in 2026?

Yes — they have been since 2020 under the CARES Act. Tampons, pads, menstrual cups, period underwear, and reusable period products all qualify with no paperwork. Most people don't realize this and have been buying them with after-tax dollars for years.

Can I use my FSA for cosmetic skincare like vitamin C serum?

No. Cosmetic skincare — anti-aging serums, brightening products, vitamin C for general glow — is not FSA or HSA eligible, even with an LMN. The IRS draws a hard line at "medically necessary." Acne treatments and dermatologist-prescribed retinoids are eligible because they treat a condition; cosmetic skincare doesn't.

What's the easiest way to know if a specific product is eligible?

Install the Caeli browser extension. It checks eligibility automatically on every product page across major retailers, shows a badge in real time, and walks you through getting an LMN if one is needed. Without Caeli, you're either Googling each item or guessing — and missing dual-purpose buys is one of the most common ways people leave HSA/FSA dollars on the table.

Bottom line

Your HSA and FSA cover way more than your last doctor visit. From sunscreen to smart wearables to home recovery gear, the surprising-but-eligible list is long — and it's where most pre-tax dollars get left on the table.

The friction has always been the same: Googling each item to check eligibility, dealing with LMNs separately, and second-guessing every checkout. Install Caeli and the badge tells you instantly. The integrated telehealth handles the LMN. The receipts archive themselves. You just shop.

TL;DR: Sunscreen, period products, Oura, Theragun, air purifier, CGM, supplements, light therapy, even a Peloton — all eligible with the right paperwork. Caeli does the paperwork.
