What an FSA covers depends on the IRS definition of a medical expense, not what your doctor says

A Flexible Spending Account (FSA) lets you set aside pre-tax money for medical costs, but the IRS has a specific list of what counts. You can use FSA funds for doctor visits, prescriptions, dental work, and vision care. You cannot use them for gym memberships, cosmetic procedures, or most over-the-counter items—even if a doctor recommends them. The rule is strict: if the IRS doesn't list it, your FSA won't pay for it, and you'll owe taxes on the money you spent.

The catch is that the list changes. Congress adds and removes items regularly, and some items sit in a gray zone where the answer depends on how you buy them. A pain reliever you pick up at the pharmacy counter counts; the same pain reliever from a grocery store shelf does not. This guide walks you through what is covered, what is not, and how to avoid spending FSA money on something you cannot reimburse.

Key Takeaways

  • Doctor visits, prescription medications, dental work, and vision care are always FSA-may be able to access, with or without a deductible.
  • Over-the-counter medicines and medical supplies are only FSA-may be able to access if you buy them from a pharmacy counter or with a prescription, not from a grocery or general store shelf.
  • Cosmetic procedures, gym memberships, vitamins, and weight-loss programs are never FSA-may be able to access, even if medically necessary.
  • Some items like insulin, certain medical devices, and menstrual products became FSA-may be able to access in recent years, so check the current IRS list if you are unsure.
  • You must keep receipts and documentation showing what you bought; your FSA administrator will ask for proof before reimbursing.

What is always covered: doctor, dental, and vision care

Visits to doctors, dentists, and eye doctors are FSA-may be able to access. This includes the office visit copay, the full cost if you are uninsured, and any tests or procedures done during the visit. Prescription eyeglasses, contact lenses, and eye exams all count. Dental cleanings, fillings, root canals, and orthodontia (braces) are covered. Mental health visits to a therapist or psychiatrist are covered if the provider is licensed and you have a diagnosis.

Hospital stays, surgery, and emergency room visits are covered. So are X-rays, lab tests, physical therapy, and chiropractic care. If a licensed healthcare provider bills you for a service, it is almost always FSA-may be able to access. The key word is licensed—unlicensed practitioners and wellness coaches typically do not may have access to, even if they call themselves doctors.

Over-the-counter medicines: the pharmacy counter rule

Over-the-counter (OTC) medicines are FSA-may be able to access only if you buy them from a pharmacy counter or with a prescription. This means pain relievers, cold medicine, allergy tablets, and antacids bought at a pharmacy register count. The same products bought from a grocery store shelf, a gas station, or an online general retailer do not count, even if they are identical.

The reason is the IRS rule: OTC medicines must be purchased in a way that shows a pharmacist was involved or a prescription was issued. If you buy ibuprofen at a grocery store, the IRS sees it as a general consumer good, not a medical expense. If you buy the same ibuprofen at a pharmacy, the IRS sees it as a medicine. This rule applies even if your FSA card works at the store—the card reader does not know where you bought the item, so you have to prove it later with a receipt.

Insulin is the major exception: it is FSA-may be able to access without a prescription and from any retailer, including grocery stores and gas stations. Menstrual products (pads, tampons, menstrual cups) became FSA-may be able to access in 2021 and can be bought from any store.

Medical supplies and equipment that are covered

Medical supplies are FSA-may be able to access if they treat or prevent a medical condition. Bandages, gauze, and first-aid supplies count. Crutches, wheelchairs, and walkers count. Hearing aids and batteries count. Diabetic test strips and lancets count. Continuous glucose monitors count. Compression stockings, back braces, and knee supports count if prescribed by a doctor.

Thermometers, blood pressure monitors, and pulse oximeters are covered. Pregnancy test kits are covered. Condoms and other contraceptives are covered. Sunscreen is not covered unless prescribed for a specific skin condition. Toothbrushes and toothpaste are not covered, even electric ones marketed for gum health.

The dividing line is whether the item treats a diagnosed condition or is a general health product. If you can buy it at a drugstore without any medical reason, it usually is not FSA-may be able to access. If it is prescribed or specifically designed to treat a condition you have, it usually is.

What is never covered: cosmetic, wellness, and lifestyle expenses

Cosmetic procedures are never FSA-may be able to access, even if medically necessary. Botox, dermal fillers, hair transplants, and teeth whitening do not count. Plastic surgery for appearance does not count. Liposuction does not count. The only exception is reconstructive surgery after an accident or illness—surgery to restore function or appearance after a burn, mastectomy, or similar trauma may be covered, but you will need documentation from your doctor that it is reconstructive, not cosmetic.

Gym memberships, fitness classes, and sports equipment are not covered. Weight-loss programs and diet plans are not covered. Vitamins and supplements are not covered, even if recommended by a doctor. Herbal remedies are not covered. Marijuana and CBD products are not covered, even in states where they are legal. Cosmetic dental work like veneers or teeth whitening is not covered.

Maternity clothes, baby formula, diapers, and childcare are not covered. Nursing bras are not covered. Fertility treatments and surrogacy are not covered. Adoption expenses are not covered. These are all considered personal or family expenses, not medical expenses, under IRS rules.

Items in the gray zone: how to check before you spend

Some items are FSA-may be able to access only under specific conditions. Certain vitamins and supplements are covered if prescribed by a doctor for a diagnosed deficiency—but over-the-counter vitamins you buy on your own are not. Acupuncture is covered if performed by a licensed acupuncturist and you have a referral from a doctor. Massage therapy is covered only if prescribed by a doctor for a medical condition, not for general wellness.

Wigs are covered if you have hair loss from a medical condition like alopecia or chemotherapy, but not for cosmetic reasons. Certain medical alert devices and monitoring systems are covered. Some home medical equipment like air purifiers or humidifiers may be covered if prescribed for a respiratory condition, but not if bought for general use.

The safest approach is to check the IRS Publication 502 or ask your FSA administrator before you spend. Most FSA companies have a searchable database on their website where you can type in an item and get an when ready answer. If the database says "not covered" or "check with your plan," contact your administrator in writing and keep the response. That way, if you are denied reimbursement later, you have documentation that you asked first.

How to get reimbursed and what documentation you need

To get reimbursed, you submit a claim to your FSA administrator with a receipt showing what you bought, when, and how much you paid. The receipt must show the item name clearly—a receipt that just says "pharmacy" or "medical supplies" without listing the specific product will be rejected. Keep receipts for at least three years in case of an audit.

Some FSA debit cards are set up to work at pharmacies and medical offices without requiring a claim—the transaction is pre-approved because the merchant is a known medical provider. But if you use your card at a general retailer or pay out of pocket, you will need to file a claim. Your FSA administrator will ask for proof that the item is FSA-may be able to access. If you cannot provide a receipt or if the receipt does not clearly show what you bought, the claim will be denied and you will owe taxes on the reimbursement.

Some items require a letter from your doctor stating that the item is medically necessary for your condition. This is common for items like compression stockings, certain medical devices, or prescribed vitamins. Ask your FSA administrator which items need a doctor's letter before you buy, so you can get the letter in advance.

Frequently Asked Questions

Can I use my FSA for my family members' medical expenses?

Yes, as long as they are your spouse or dependent children claimed on your tax return. You can use FSA money for their doctor visits, prescriptions, dental work, and other covered expenses. You cannot use it for adult children or other relatives unless they are your legal dependents.

Are prescription glasses and contacts covered by FSA?

Yes. Eyeglasses, contact lenses, and eye exams are all FSA-may be able to access. You can also use FSA funds for lens coatings, frames, and contact lens solution. Sunglasses are not covered unless they are prescription sunglasses.

What happens if I use my FSA money on something that is not covered?

If you are reimbursed for a non-covered expense, you will owe income tax and a 20 percent penalty on that amount. If you spend your own money on a non-covered item and then try to claim it, the claim will be denied. The best protection is to ask your FSA administrator before you spend.

Can I use FSA money for telehealth visits?

Yes. Telehealth visits to licensed doctors, therapists, and other healthcare providers are FSA-may be able to access. You can use FSA funds to pay the visit fee. Some telehealth platforms accept FSA debit cards directly; others require you to file a claim with a receipt.

Are dental implants and braces covered by FSA?

Yes. Orthodontia (braces), dental implants, crowns, and other restorative dental work are FSA-may be able to access. Cosmetic dental work like teeth whitening and veneers is not covered. If your dentist bills something as both cosmetic and restorative, ask them to itemize the bill so you can claim only the restorative portion.
