HSA FSA-Eligible Items: 47 Surprises That Save $1,200/yr

The average American forfeits $408 in unused FSA dollars every December, according to a 2024 Money.com analysis of EBRI data. Not because they don't need healthcare — because they think their FSA only covers copays, prescriptions, and bandaids. It doesn't. The CARES Act of 2020 quietly expanded the eligible list to include over 20,000 products, and almost nobody updated their mental checklist.

One of the biggest under-used categories? Direct-to-consumer lab testing. A comprehensive thyroid panel runs $400+ at a doctor's office once you factor in the visit copay, the draw fee, and the lab markup. The exact same Quest Diagnostics panel — same lab, same tubes, same result — is $69 direct. Get this test at HealthLabs (skip the $200-300 doctor markup) and it's 100% FSA/HSA-eligible with an itemized receipt for reimbursement. Below is the actual list of what your pre-tax dollars will cover before December 31 takes them away.

The 12 Surprising HSA FSA-Eligible Items Most People Miss

Forget the obvious stuff (prescriptions, glasses, dental). These are the items that consistently surprise FSA holders when I run the list past them:

• Sunscreen (SPF 15+) — Banana Boat, Neutrogena, the whole CVS aisle. Roughly $30/yr for a family.
• Acne treatments — CeraVe, La Roche-Posay Effaclar, Differin gel. ~$120/yr if you have a teenager.
• Period products — tampons, pads, menstrual cups, Thinx underwear. ~$80-150/yr.
• At-home COVID/flu/strep tests — BinaxNOW, Lucira. $12-25 each.
• Lab tests without a doctor visit — Vitamin D, thyroid, A1C, STI panels. $29-89 each direct.
• Blue-light glasses with Rx — Warby Parker, Zenni. ~$95.
• Breast pumps and accessories — Spectra, Medela. $150-300 covered fully.
• Smart thermometers — Kinsa, Withings. $40-60.
• Massage guns (with a Letter of Medical Necessity) — Theragun. $200-400.
• Therapy and counseling copays — including BetterHelp if billed properly.
• Chiropractic visits — $50-80/session.
• Hearing aids and batteries — $1,000-4,000.

That list alone, used aggressively, drains $800-1,500 of an FSA before year-end. The IRS Publication 502 is the authoritative source — bookmark it.

Lab Tests: The Biggest HSA/FSA Arbitrage Nobody Talks About

Here's the math that makes my eyes roll every time. A primary care visit averages $171 (Debt.org, 2024). The draw fee is typically $20-40. The lab itself marks up its own internal cost by 200-400% when billed through a physician. End result: a vitamin D test that costs the lab $4 to run gets billed to you at $250-300.

Direct-to-consumer pricing kills that markup. Walk into any LabCorp or Quest patient service center with an order from a telehealth physician (the order is included free), and you pay the wholesale-adjacent rate:

Every dollar of that comes out of pre-tax FSA/HSA money, which itself is a 22-32% discount depending on your bracket. So a $69 thyroid panel is actually costing your take-home pay closer to $47. Get this test at HealthLabs (skip the $200-300 doctor markup) — the receipt is automatically formatted for FSA reimbursement.

The Counter-Intuitive Rule: OTC Drugs Don't Need a Prescription Anymore

Here's the thing 80% of FSA holders still get wrong: over-the-counter medications became permanently FSA-eligible without a prescription in March 2020. The CARES Act reversed a 2011 rule that had required a doctor's note for every bottle of Advil. Almost nobody updated their habits.

That means Tylenol, Advil, Zyrtec, Claritin, Pepcid, Mucinex, Robitussin, Tums, Imodium, Benadryl, Aleve, Aspirin, Sudafed, Vicks, Theraflu, Nyquil, Dayquil, NicoDerm, Nicorette, Rogaine, prenatal vitamins (with LMN), heating pads, ice packs, wrist braces, ankle braces, KT tape, ace bandages, and basically the entire pharmacy aisle at Target are eligible. You can buy them with your FSA card directly at Amazon's FSA Store, Walgreens, or CVS. Receipts auto-categorize.

A family of four typically spends $250-400/yr on OTC meds. That's $250-400 of pre-tax money you've been paying with after-tax dollars for the last six years if you didn't know about the rule change.

The December 31 Cliff and How to Beat It

Most FSAs are use-it-or-lose-it. A minority offer a $640 carryover (2024 IRS limit) or a 2.5-month grace period — check your plan documents, don't assume. If you've got an unspent balance and three weeks left, here's the smart-spend order:

1. Stock the medicine cabinet — $200-300 of OTC meds, sunscreen, first aid.
2. Run your annual labs early — thyroid, vitamin D, A1C, lipid panel. $150-250 total direct.
3. Buy a year of contact lenses — $200-400.
4. Book the dental cleaning your insurance doesn't fully cover — the gap is eligible.
5. Get the new glasses prescription you've been putting off.
6. Buy the breast pump, the massage gun (with LMN), or the smart thermometer.

A disciplined December sweep clears $800-1,500 of balance without buying anything you wouldn't have bought anyway in the next six months. The IRS doesn't care if you stockpile sunscreen.

HSA vs FSA: Why the Same List Behaves Differently

The eligible-items list is identical between HSAs and FSAs — IRS Pub 502 governs both. But the strategy diverges hard. FSA money is annual and forfeits. HSA money is yours forever, rolls over, invests tax-free, and at age 65 becomes a traditional IRA for any purpose. The optimal HSA play is the opposite of FSA: pay healthcare costs out-of-pocket, save the receipts in a shoebox (or a Google Drive folder), and reimburse yourself decades later after the balance has compounded at 7-9%.

A $69 lab test paid from an HSA today, left to grow for 25 years at 8%, becomes a $472 tax-free withdrawal in retirement. That's the actual move for HSA holders under 50 — let the receipts age like wine.

Bottom line: if you've got FSA money sitting unused with the December deadline closing in, run your annual lab work now. Get this test at HealthLabs (skip the $200-300 doctor markup), get the itemized receipt in your inbox in 15 minutes, and submit it for reimbursement before the balance disappears on January 1.
