FSA funds cover specific medical and dental expenses, not everyday purchases
Your Flexible Spending Account (FSA) money can only be spent on items the IRS classifies as medical care. That means you can use it for doctor visits, prescription drugs, and dental work — but not for groceries, gym memberships, or over-the-counter vitamins without a prescription. The IRS publishes a list of what counts, and your FSA plan administrator enforces it. If you buy something that does not may have access to and try to reimburse yourself, the claim will be denied and you will lose that money.
The reason for these restrictions is tax law. FSA contributions come out of your paycheck before taxes, which saves you money on income tax. In exchange, the government limits what you can buy. Your employer's plan may be stricter than the IRS rules — some plans do not cover certain items the IRS technically allows — so check your plan documents or call your plan administrator before you spend.
Key Takeaways
- FSA money covers medical, dental, and vision expenses that treat or prevent illness, but not cosmetic procedures or general wellness items.
- Over-the-counter medications and supplies require a prescription from your doctor to be FSA-may be able to access, even if you can buy them without one at a pharmacy.
- Your employer's FSA plan may have stricter rules than the IRS allows, so you should review your plan documents or contact your administrator before purchasing.
- Denied claims mean you lose the money permanently — there is no refund or carryover unless your plan offers a grace period or rollover option.
- Keep receipts and documentation for every FSA purchase in case your plan administrator or the IRS asks for proof later.
Medical expenses that FSA covers
FSA money covers doctor visits, hospital stays, surgery, lab tests, X-rays, and mental health counseling. You can use it to pay copays, coinsurance, and deductibles on your health insurance. You can also use it for prescription medications, even if your insurance covers part of the cost — the FSA can pay your share.
Dental work is covered: cleanings, fillings, root canals, crowns, braces, and extractions all count. Vision care is covered too: eye exams, glasses, contact lenses, and laser eye surgery. Medical equipment like crutches, wheelchairs, hearing aids, and blood pressure monitors qualifies. So do items like bandages, first-aid kits, thermometers, and pain relievers — but only if you have a prescription for the pain reliever.
Therapy and rehabilitation are covered: physical therapy, occupational therapy, speech therapy, and chiropractic care all count if they treat a medical condition. Fertility treatments, including in vitro fertilization (IVF), are covered. Prescription birth control is covered. Insulin and diabetes supplies are covered. If you are unsure whether a specific medical item or service counts, ask your doctor or your plan administrator before you pay.
Over-the-counter items that require a prescription
You can buy over-the-counter medications and supplies with FSA money, but only if your doctor writes a prescription for them. This includes pain relievers like ibuprofen and acetaminophen, allergy medications, cold medicines, antacids, and topical creams. You can also use FSA funds for over-the-counter medical supplies like bandages, gauze, heating pads, ice packs, and cough drops — again, only with a prescription.
The prescription does not mean the medication is stronger or different from what you buy without one. It means your doctor has documented that you need it for a medical reason. You take the prescription to the pharmacy, buy the item, and then submit the receipt and prescription copy to your FSA plan for reimbursement. Some pharmacies will not fill a prescription for an over-the-counter item, so call ahead and ask.
Sunscreen does not count, even with a prescription, because the IRS treats it as a cosmetic product. Toothpaste and mouthwash do not count either. Vitamins and supplements do not count unless your doctor prescribes them to treat a specific deficiency or medical condition — a general multivitamin does not may have access to.
What FSA does not cover
Cosmetic procedures are not covered, even if they are performed by a doctor. That includes Botox, dermal fillers, teeth whitening, hair removal, and cosmetic surgery. The exception is if the procedure is medically necessary — for example, reconstructive surgery after an accident or burn is covered, but elective cosmetic surgery is not.
Gym memberships, fitness classes, and sports equipment are not covered, even if your doctor recommends exercise. Weight loss programs and diet plans are not covered. Cosmetic dental work like veneers or bonding for appearance only is not covered, though bonding to repair a cavity is. Eyeglasses frames are covered, but only the cost of the frames and lenses — not designer frames or premium coatings beyond what is medically necessary.
Toiletries and personal care items are not covered: toothpaste, shampoo, soap, deodorant, and razors do not count. Maternity clothes do not count. Childcare is not covered. Travel to medical appointments is not covered. Meals and lodging during a hospital stay are not covered (the hospital bill itself is, but not your food or a hotel room nearby).
How to know what your specific plan covers
Your employer's FSA plan may have its own rules that are stricter than the IRS allows. Some plans do not cover certain dental work, vision care, or medical equipment. Some plans have a list of pre-approved items and will deny anything not on it. You need to know your plan's specific rules before you spend.
Your plan documents should list what is and is not covered. If you have them, read the section on covered expenses. If you do not have them, contact your plan administrator — this is usually your HR department or a third-party benefits company. Ask them for a list of covered items or ask about a specific purchase before you make it. Many administrators have a website or phone line where you can check coverage on individual items.
Keep a copy of your plan's covered expenses list for your records. If a claim is denied, you can appeal it if you believe it should be covered under your plan or under IRS rules. Your plan administrator will tell you how to file an appeal and what documentation you need to provide.
Documentation and reimbursement
When you use your FSA debit card at a pharmacy or doctor's office, the transaction may go through immediately. But your plan administrator will still ask you to submit proof that the purchase was FSA-may be able to access. This is called substantiation. You need to provide a receipt that shows what you bought and the date, plus any other documentation the plan asks for.
If you cannot provide proof, your plan administrator may deny the reimbursement or ask you to repay the money. Keep receipts for at least three to five years in case you are audited. If you pay out of pocket and then submit a claim for reimbursement, you will need the receipt plus a statement from your doctor or provider confirming the service or item was medically necessary.
Some plans use a debit card that is pre-loaded with your FSA balance. Others require you to pay out of pocket and submit receipts for reimbursement. A few plans use both methods. Check your plan documents to understand how your plan works and what documentation you need to keep.
Frequently Asked Questions
Can I use my FSA to buy over-the-counter pain relievers without a prescription?
No. Over-the-counter medications, including pain relievers, require a prescription from your doctor to be FSA-may be able to access. You can buy them at any pharmacy, but you need the prescription to submit for reimbursement. Call your doctor's office and ask them to send a prescription to your pharmacy.
Are vitamins and supplements covered by FSA?
General vitamins and supplements are not covered. But if your doctor prescribes a specific vitamin or supplement to treat a medical condition — such as vitamin D for a deficiency or iron for anemia — then it is covered. You will need the prescription to submit with your reimbursement claim.
Can I use FSA money for dental work like teeth whitening?
Teeth whitening is cosmetic and not covered. But routine cleanings, fillings, root canals, crowns, and braces are all covered. If you are unsure whether a specific dental procedure counts, ask your dentist or your FSA plan administrator before the work is done.
What happens if I buy something that is not FSA-may be able to access?
If you submit a claim for a non-may be able to access item, your plan will deny it and you will not be reimbursed. The money is gone — you cannot get it back or use it for something else. That is why it is important to check your plan's rules or ask your administrator before you make a purchase.
Do I need to keep receipts for FSA purchases?
Yes. Your plan administrator may ask you to submit receipts to prove that your purchase was FSA-may be able to access. Keep receipts for at least three to five years. If you cannot provide proof when asked, your plan may deny the reimbursement or ask you to repay the money.
