FSA money covers medical costs that your insurance doesn't pay for, plus some items insurance won't cover at all

Your Flexible Spending Account (FSA) can pay for prescription medications, doctor visits, dental work, vision care, and medical equipment — basically anything a doctor says you need to treat or manage a health condition. The IRS publishes a list of what counts, and it's longer than most people expect. The catch: FSA money only works for you and your spouse and dependents on your tax return, and you lose any money you don't spend by the end of the plan year (or a short grace period, depending on your employer's rules).

What makes FSA different from regular insurance is that it covers some things insurance won't touch. You can use FSA funds for over-the-counter pain relievers, allergy medicine, and cold medicine without a prescription. You can pay for glasses, contacts, and hearing aids. You can cover copays, deductibles, and coinsurance. If your insurance denies a claim, FSA can sometimes fill that gap — as long as the item itself is on the IRS-approved list.

Key Takeaways

  • FSA covers prescription drugs, medical equipment, doctor and dentist visits, and vision and hearing care that a doctor says you need.
  • Over-the-counter medications like pain relievers and allergy medicine count, but only if you have a prescription or a doctor's note saying you need them.
  • FSA pays for copays, coinsurance, and deductibles, but not for health insurance premiums themselves.
  • Cosmetic procedures and general wellness items like vitamins and gym memberships do not count, even if they improve your health.
  • Money left in your FSA at the end of the year is forfeited, so tracking what you spend is important to avoid waste.

Prescription and Over-the-Counter Medications

Any medication your doctor prescribes is FSA-may be able to access, whether it's for a chronic condition or a one-time infection. This includes birth control, inhalers, antibiotics, and blood pressure medication. You pay with your FSA debit card at the pharmacy, and the pharmacist verifies the prescription.

Over-the-counter medications are trickier. Aspirin, ibuprofen, allergy pills, antacids, and cold medicine all count — but only if you have a prescription or a written statement from your doctor saying you need them for a specific condition. You cannot just buy them off the shelf without documentation. Some employers' FSA plans are stricter than others, so check your plan documents or call your FSA administrator to confirm what counts at your workplace.

Medical Equipment and Supplies

FSA covers medical equipment your doctor says you need: blood pressure monitors, glucose meters, thermometers, crutches, wheelchairs, and orthopedic braces. Diabetic supplies — test strips, lancets, and syringes — are all covered. Bandages, gauze, and first-aid supplies count. Heating pads and ice packs for injury recovery are covered.

The rule is simple: if it's medical equipment or a supply used to treat a diagnosed condition, it's usually FSA-may be able to access. Keep receipts and any documentation from your doctor, because your FSA administrator may ask for proof that the item was medically necessary. Some items that sound medical but are actually preventive or general wellness — like a regular thermometer you buy just to have on hand — may not count, so ask before you buy if you're unsure.

Dental, Vision, and Hearing Care

Dental work is one of the biggest FSA expenses for most people. Cleanings, fillings, root canals, crowns, and orthodontia all count. You can use FSA to pay your dentist directly, or to cover the portion your dental insurance doesn't pay. If you don't have dental insurance, FSA can cover the full cost of the work.

Vision care includes eye exams, glasses, contact lenses, and contact solution. Hearing aids and hearing aid batteries are covered. Cochlear implants and related equipment count too. These are areas where FSA often saves the most money, because dental and vision insurance (when you have it) usually has high copays and deductibles, and FSA lets you pay those costs with pre-tax dollars.

Doctor Visits and Medical Services

FSA covers copays and coinsurance for doctor visits, urgent care, emergency room visits, and hospital stays. If your plan has a $50 copay for a specialist visit, you can pay it with FSA money. If you have a $2,000 deductible and you've met it, FSA can cover the coinsurance (your share of the cost after insurance pays its part).

Mental health and therapy visits count. Physical therapy, occupational therapy, and chiropractic care are covered if a doctor refers you. Lab work and imaging (X-rays, MRIs, ultrasounds) are covered. Vaccinations and immunizations are covered. Basically, if it's a service a licensed healthcare provider gives you to diagnose or treat a health condition, FSA can pay for it.

What Does Not Count

Cosmetic procedures are not covered, even if they improve how you feel. Botox, teeth whitening for appearance, and elective plastic surgery do not count. However, if a procedure is medically necessary — like surgery to repair a deviated septum that affects breathing — it may be covered even if it also improves appearance.

General wellness items are not covered: vitamins and supplements (unless prescribed by a doctor for a deficiency), gym memberships, weight loss programs, and fitness equipment do not count. Health insurance premiums themselves are not FSA-may be able to access, though copays and deductibles are. Toiletries, sunscreen, and over-the-counter skincare products do not count, even if they prevent or treat a skin condition — unless a doctor prescribes them specifically.

How to Know If Something Counts

The IRS maintains a list of may be able to access medical expenses in Publication 502, but it's dense and not always clear. A simpler approach: ask yourself whether a doctor would prescribe or recommend this item to treat a specific health condition you have. If yes, it probably counts. If it's something you'd buy anyway for general health or appearance, it probably doesn't.

When in doubt, contact your FSA plan administrator before you buy. Most employers have a customer service number on the back of your FSA debit card or in your plan documents. They can tell you in five minutes whether a specific item is covered under your plan. It's worth the call, because buying something that doesn't count means you lose that money and cannot get it back.

Frequently Asked Questions

Can I use FSA to pay for my spouse's or child's medical expenses?

Yes, if they are your spouse or tax dependent. You can use one FSA account to pay for medical expenses for everyone on your tax return. The money does not have to be divided equally — you can spend the whole balance on one person if needed.

Do I need a receipt to prove I bought something with FSA money?

You need a receipt if your FSA administrator asks for one, which they may do randomly or if the purchase seems unusual. Keep receipts for at least three years. If you cannot produce a receipt, the administrator may deny the claim and ask you to repay the money.

Can I use FSA for items I buy online or by mail order?

Yes, as long as the item itself is FSA-may be able to access and you can provide a receipt showing what you bought. Some online retailers (like Amazon) sell FSA-may be able to access items, but you have to know which ones count. Check the product description or call the retailer to confirm before you order.

What happens if I buy something and later find out it doesn't count?

If you used your FSA debit card, the administrator may reverse the charge and ask you to repay the money out of pocket. If you paid out of pocket and submitted a claim, they will deny it. Either way, that money is gone — you cannot get it back or roll it forward to next year.

Are pet medications and veterinary care covered?

No. FSA only covers medical expenses for you, your spouse, and your tax dependents. Pets are not dependents for FSA purposes, so veterinary care and pet medications do not count, even if they are prescribed by a veterinarian.
