FSA money covers medical costs your insurance doesn't fully pay for
Your Flexible Spending Account (FSA) holds pre-tax dollars you set aside to pay for may have access to medical expenses — the specific list matters because the IRS defines what counts. The money can cover copays, deductibles, coinsurance, and some products your health plan won't cover at all. You cannot use FSA funds for anything the IRS has not approved, even if it feels medical.
The key rule: the expense must be for diagnosis, treatment, or prevention of a disease or condition. Cosmetic procedures, general wellness items, and most over-the-counter products do not may have access to, even if a doctor recommends them. Some items sit in a gray area — the IRS publishes a list, but it changes, and some items require a doctor's letter to count.
You spend FSA money by submitting receipts to your plan administrator or using a debit card linked to the account. Either way, you need proof the expense was may have access to. Keeping receipts and invoices is not optional — your plan can ask for documentation months later.
Key Takeaways
- FSA funds cover copays, deductibles, coinsurance, and some medical products your insurance does not pay for, but only if the IRS classifies them as may have access to medical expenses.
- Over-the-counter medications, vitamins, and cosmetic treatments do not may have access to unless you have a doctor's prescription or letter stating medical necessity.
- You must keep receipts and invoices for every FSA purchase because your plan administrator can request proof of may have access to expenses at any time.
- Some items like insulin, crutches, and hearing aids always may have access to; others like sunscreen or teeth whitening never do; and some require documentation to prove they treat a specific condition.
Medical services and procedures that always may have access to
Doctor visits, dentist appointments, eye exams, and mental health counseling are all may have access to expenses. You can use FSA funds to pay the copay, the deductible, or the full cost if you have not met your deductible yet. This includes telehealth visits and virtual therapy sessions — the format does not change the rule.
Prescription medications always may have access to. Over-the-counter drugs like ibuprofen, cold medicine, and allergy tablets do not may have access to unless you have a written prescription from a doctor. A prescription for an OTC item is rare but possible — if your doctor writes one, keep it with your receipt.
Surgical procedures, hospital stays, X-rays, lab tests, and physical therapy all count. You can use FSA funds to cover the patient portion of these costs. Dental work — fillings, cleanings, root canals, orthodontia — qualifies. Vision correction through glasses, contacts, or LASIK surgery qualifies.
Medical equipment and supplies that may have access to
Durable medical equipment — items a doctor prescribes to treat or manage a condition — qualifies. This includes crutches, wheelchairs, walkers, blood pressure monitors, glucose meters, and nebulizers. The item must be prescribed or recommended by a healthcare provider, and you should keep that documentation.
Insulin and other diabetes supplies (test strips, lancets, syringes) may have access to. Hearing aids and batteries may have access to. Orthopedic shoes, braces, and compression stockings may have access to if prescribed for a medical condition. Bandages, gauze, and first-aid supplies may have access to. Incontinence products may have access to.
Over-the-counter medical devices can be tricky. A pulse oximeter or thermometer qualifies. A heating pad qualifies. Sunscreen does not may have access to, even though it prevents skin damage, because the IRS does not classify it as treatment or prevention of disease. Vitamins and supplements do not may have access to unless a doctor prescribes them to treat a specific deficiency.
Items that do not may have access to, even if medical
Cosmetic procedures and products do not may have access to — this includes teeth whitening, hair removal, wrinkle creams, and cosmetic surgery. The IRS rule is strict: if the primary purpose is appearance rather than treating a disease, it does not count. A facelift does not may have access to. Botox does not may have access to. Veneers for cosmetic reasons do not may have access to.
General wellness and fitness do not may have access to. Gym memberships, yoga classes, and fitness equipment do not count, even if your doctor recommends exercise. Weight-loss programs do not may have access to unless they treat a specific diagnosed condition like obesity-related diabetes, and even then documentation is required.
Toiletries and personal care do not may have access to — toothpaste, deodorant, shampoo, and soap do not count. Maternity clothes do not may have access to. Childcare and babysitting do not may have access to, even though they may be necessary for you to work. Fertility treatments and surrogacy costs do not may have access to.
Gray-area items that need documentation
Some expenses may have access to only if you have a doctor's letter stating they treat a specific medical condition. Weight-loss programs, for example, do not may have access to on their own, but a program prescribed to treat obesity-related hypertension or diabetes might. Acupuncture does not automatically may have access to, but it might if a doctor prescribes it for chronic pain. A letter from the doctor should state the condition being treated and why this specific service is medically necessary.
Certain over-the-counter items fall into this category. Antacids, anti-diarrheal medication, and allergy medicine do not may have access to without a prescription, but if your doctor writes a prescription for them, they do. Some plans are stricter than others — check your plan documents or call your administrator before buying.
Mental health services may have access to, but only if provided by a licensed healthcare provider. A therapist or psychiatrist counts. A life coach or wellness counselor does not, even if they address emotional health. Meditation apps do not may have access to on their own.
How to know before you spend
Your plan administrator publishes a list of may have access to expenses — ask for it or check your plan documents. The IRS also publishes Publication 502, which details what counts. If an item is not on either list and you are not sure, contact your plan administrator before you buy. They can tell you whether a specific product or service qualifies under your plan.
If you think an item qualifies but it is not obvious, ask your doctor for a letter. The letter should state the condition being treated and why this specific item or service is medically necessary. Keep the letter with your receipt. Your plan can request it later as proof.
When you submit a receipt for reimbursement, include the date, the provider's name, the service or product, and the amount paid. If the receipt does not show what you bought (for example, a pharmacy receipt that just says "pharmacy"), attach a note explaining what the purchase was for. The clearer your documentation, the faster your reimbursement.
What happens if you spend FSA money on non-may have access to expenses
If you use your FSA debit card or submit a receipt for a non-may have access to expense, your plan administrator may deny the reimbursement. If they catch it, you will have to pay the amount back out of pocket. If they do not catch it at the time, they can still ask for documentation later — sometimes months later — and deny it then.
Using FSA funds for non-may have access to expenses does not trigger a tax penalty, but you lose the tax benefit. The money you spent comes out of your pre-tax account, so you do not owe taxes on it, but you also do not get the deduction back. The bigger risk is that your plan administrator flags your account for audit if they see a pattern of questionable claims.
Some FSA debit cards have built-in controls — they will decline a purchase at a pharmacy if the item is not on the may have access to list. Other cards do not, and you submit receipts after the fact. Know which system your plan uses so you do not buy something and then have to dispute it.
Frequently Asked Questions
Can I use my FSA for my spouse's or child's medical expenses?
Yes. FSA funds can pay for may have access to medical expenses for you, your spouse, and your dependents — including adult children if you claim them on your taxes. The person receiving the care does not have to be on your health insurance plan. Keep receipts showing the patient's name and relationship to you.
Does my FSA cover pet medical expenses?
No. Veterinary care and pet medications do not may have access to as medical expenses under IRS rules. The FSA is limited to human medical care. If you have a service animal prescribed for a disability, the training and care may have different rules — contact your plan administrator.
Can I use FSA money for my deductible or premium payments?
No. FSA funds cannot pay your health insurance premiums or deductibles. They can only pay for may have access to medical expenses after you have already incurred them. You can use FSA money to cover the copay or coinsurance portion of a visit, but not the deductible itself.
What if I buy something I think qualifies and my plan denies it later?
Ask your plan administrator why it was denied and request the specific IRS rule or plan language that disqualifies it. If you disagree, ask whether a doctor's letter would change the decision. If the denial stands, you can appeal through your plan's dispute process, though reversals are uncommon. Keep the documentation in case you need it for your taxes.
Can I use my FSA for items I buy online or at a regular store?
Yes, as long as the item itself qualifies. You can buy a blood pressure monitor online, at a pharmacy, or at a medical supply store — the retailer does not matter. You can use your FSA debit card at any store. Keep the receipt showing what you bought and the amount. Online purchases are fine as long as you can document what the expense was for.
