FSA funds cover specific medical and dental expenses, not general health purchases
Your FSA account pays for items the IRS classifies as medical care — mostly things a doctor prescribes, a dentist performs, or a pharmacy dispenses. You cannot use FSA money for vitamins, cosmetics, gym memberships, or over-the-counter items unless a doctor writes a letter saying you need them for a diagnosed condition. The IRS publishes a list of what counts, and your plan administrator enforces it. If you buy something and it turns out to be ineligible, you may have to pay the money back out of pocket.
The rules exist because FSA contributions come from pre-tax dollars — money that would otherwise be taxed as income. In exchange, the government restricts what you can spend it on. Your employer's plan document may be stricter than the IRS rules, so check your summary of benefits or call your plan administrator before making a large purchase.
Key Takeaways
- FSA funds cover doctor visits, prescriptions, dental work, vision care, and medical equipment that a doctor prescribes or a dentist recommends.
- Over-the-counter medications like pain relievers and allergy pills require a doctor's written prescription to be FSA-may be able to access, even though you can buy them without one at a pharmacy.
- Cosmetic procedures, gym memberships, vitamins, and general wellness products are not covered unless a doctor documents that you need them to treat a specific medical condition.
- Your plan administrator or benefits website usually has a searchable list of may be able to access items, and you can ask before you spend the money.
Medical visits and procedures you can pay for
FSA money covers the cost of seeing a doctor, dentist, eye doctor, or mental health professional. This includes office visit copays, deductibles, and the full cost of a visit if you have not met your deductible yet. It also covers procedures those professionals perform: dental cleanings and fillings, eye exams and glasses, therapy sessions, and surgery.
Prescription medications are always FSA-may be able to access. Over-the-counter drugs like ibuprofen, allergy pills, and cold medicine are may be able to access only if a doctor writes a prescription for them — the prescription itself is what makes them count, even though you can buy the same product without one. Some plans let you submit the prescription retroactively; others require you to have it before you buy. Ask your plan administrator which applies to you.
Medical equipment and supplies are covered if a doctor prescribes them: crutches, wheelchairs, hearing aids, blood glucose monitors, and insulin. Bandages, gauze, and first-aid supplies count. Pregnancy tests and contraceptive devices are FSA-may be able to access. Orthopedic shoes are covered only if a doctor prescribes them for a medical condition, not for general comfort.
Dental and vision expenses
Dental work is one of the largest FSA expenses for most people. Cleanings, fillings, root canals, crowns, extractions, and orthodontia (braces) are all covered. Dental X-rays and exams count. If your dentist recommends a procedure, it is FSA-may be able to access even if your dental insurance does not cover it or covers only part of it.
Vision care includes eye exams, glasses, contact lenses, and contact lens solution. Laser eye surgery (LASIK) is covered. Sunglasses are not, even if you need them for a medical reason, unless a doctor prescribes them specifically for a condition like photophobia (light sensitivity).
Items that require a doctor's letter
Some purchases are FSA-may be able to access only if you have written documentation from a doctor saying you need them for a medical condition. This category includes vitamins and supplements, over-the-counter pain relievers and allergy medications, and certain medical devices.
The letter does not have to be formal. Your doctor can write a brief note on a prescription pad saying something like "Patient requires Vitamin D supplementation for deficiency" or "Patient needs over-the-counter ibuprofen for chronic pain management." Keep the letter with your receipts. If your plan administrator questions the purchase later, you can submit the letter as proof.
Some common items that fall into this category: probiotics, antacids, hydrocortisone cream, antihistamine creams, and certain pain relief patches. The same product might be may be able to access for one person (with a doctor's letter) and ineligible for another (without one).
What is not covered, even with a prescription
Cosmetic procedures are not FSA-may be able to access unless they are reconstructive — meaning they repair damage from injury, disease, or birth defect. Botox, teeth whitening, and hair removal are cosmetic and not covered. Reconstructive surgery after an accident or cancer treatment is covered.
General wellness products are not covered: vitamins without a doctor's letter, gym memberships, fitness classes, weight loss programs, and diet supplements. Sunscreen is not covered. Toothpaste and mouthwash are not covered. Deodorant is not covered. These are considered personal care items, not medical care.
Childcare, long-term care insurance, and life insurance cannot be paid with FSA funds. Neither can cosmetic dentistry like veneers or teeth whitening. Maternity clothes are not covered. Pet medical expenses are not covered, even if prescribed by a veterinarian.
How to know if something is may be able to access before you buy
Most FSA debit cards come with a website or app where you can search for specific items. Type in the product name and the system will tell you whether it is may be able to access. This is the fastest way to check.
If the search tool does not have the item, call your plan administrator. The number is on your FSA card or in your benefits paperwork. Have the product name and manufacturer ready. They can tell you in a few minutes whether it counts.
Keep your receipts for everything you buy with FSA funds. If the IRS or your plan administrator audits your account, you will need to show proof that the items were medical expenses. A receipt alone is usually enough, but for borderline items, a doctor's letter is your protection.
What happens if you buy something ineligible
If you use your FSA debit card for an ineligible purchase, your plan administrator may flag it and ask you to prove it was medical. If you cannot, you may have to repay the money to your FSA account out of pocket. This is not a penalty — it is simply removing the pre-tax benefit from that purchase.
Some plans audit purchases randomly; others only when a claim looks unusual. If you are unsure about an item, ask before you buy rather than risk having to pay it back later.
Frequently Asked Questions
Can I use my FSA for over-the-counter pain relievers without a prescription?
Not unless your doctor writes a prescription for them. Even though you can buy ibuprofen or acetaminophen without a prescription at any pharmacy, the FSA requires a doctor's written order to make them may be able to access. Some plans let you get the prescription after you buy; others require it beforehand. Check with your plan administrator.
Are vitamins and supplements covered by FSA?
Only if a doctor writes a letter saying you need them for a diagnosed deficiency or medical condition. A general multivitamin is not covered. Vitamin D for a documented deficiency, or iron for anemia, would be covered with a doctor's letter. Ask your doctor to write the letter before you buy.
Can I use FSA money for my gym membership or fitness classes?
No. Gym memberships and fitness classes are considered general wellness, not medical care, and are not FSA-may be able to access. The exception is if a doctor prescribes physical therapy for an injury or condition — that is covered, but only if performed by a licensed physical therapist, not a personal trainer.
Is teeth whitening covered by FSA?
No. Teeth whitening is a cosmetic procedure and not FSA-may be able to access. Dental work that treats disease or damage — like fillings, root canals, and crowns — is covered. Orthodontia (braces) is covered. But cosmetic improvements to your teeth are not.
What if my plan administrator says something is not may be able to access but I think it should be?
Ask them to explain which IRS rule makes it ineligible. If you disagree, you can submit a written appeal with documentation — usually a doctor's letter explaining the medical necessity. Some plans have an appeals process; others do not. It is worth asking, especially for borderline items like orthopedic shoes or specialized medical equipment.
