FSA money covers medical expenses your insurance won't pay for — and some it will
A Flexible Spending Account (FSA) holds pre-tax dollars you set aside each year to pay for out-of-pocket medical costs. You can use that money for copays, deductibles, prescriptions, and dozens of other health expenses. The IRS publishes a specific list of what counts, and it is narrower than many people think — you cannot buy vitamins, toothpaste, or gym memberships. But you can pay for things your insurance covers and things it does not, as long as the IRS classifies them as medical care.
The catch is timing: you choose how much to contribute at the start of the year, and most of that money is forfeited if you do not spend it by December 31. Some employers offer a grace period (usually 2.5 months into the next year) or a carryover of up to $640, but neither is may provide. That means you need to estimate your medical spending accurately, or you lose money.
Key Takeaways
- FSA funds pay for copays, coinsurance, deductibles, prescription drugs, and medical equipment — whether your insurance covers them or not.
- Over-the-counter medications and medical supplies require a prescription or doctor's note to may have access to, even if you buy them without one at the pharmacy.
- Common expenses like dental work, vision care, mental health treatment, and medical devices all count as FSA-may be able to access.
- Money left unspent at year-end is forfeited unless your employer offers a grace period or carryover, so estimate conservatively.
- You cannot use FSA funds for insurance premiums, cosmetic procedures, or general wellness items like vitamins or gym memberships.
Prescription drugs and over-the-counter medications with a prescription
Any prescription medication your doctor writes counts as FSA-may be able to access, whether your insurance covers it or not. You pay with your FSA debit card or submit a receipt for reimbursement. Over-the-counter drugs — allergy medicine, pain relievers, cold medicine, antacids — also count, but only if you have a prescription or a doctor's note saying you need them. A pharmacist cannot write that note; it has to come from your doctor.
This rule trips up many people. You can walk into a pharmacy and buy ibuprofen without a prescription, but you cannot use FSA money for it unless you have documentation from your doctor first. If you take over-the-counter medications regularly, ask your doctor to write a standing prescription or a letter listing the medications you use for a medical reason. Keep that letter with your FSA records.
Copays, deductibles, and coinsurance
Every dollar you pay out of pocket to your insurance counts as FSA-may be able to access. That includes copays at the doctor's office, the deductible you meet before insurance kicks in, and coinsurance (the percentage you pay after the deductible). You can use FSA money to cover these costs whether your plan is an HMO, PPO, or high-deductible plan paired with an HSA.
If you have both an FSA and an HSA, you cannot use FSA money for the same expense — that would be double-dipping. But you can use your FSA to pay copays and coinsurance while using your HSA for other may have access to medical expenses, or vice versa. Keep receipts and explanation-of-benefits statements so you can prove which account paid for what.
Dental, vision, and mental health care
Dental work is FSA-may be able to access: cleanings, fillings, root canals, crowns, orthodontics, and extractions all count. Vision care also qualifies — eye exams, glasses, contact lenses, and laser eye surgery. Mental health treatment, including therapy and psychiatric care, is covered. You pay the dentist, eye doctor, or therapist with your FSA card or submit receipts for reimbursement.
If your employer's dental or vision plan has a separate deductible or copay, that counts too. Some people use their FSA to cover the out-of-pocket costs of dental and vision insurance they buy separately, which can make sense if those plans have high deductibles.
Medical equipment and supplies
Durable medical equipment — crutches, wheelchairs, hearing aids, blood pressure monitors, glucose meters — is FSA-may be able to access. So are medical supplies: bandages, syringes, test strips, compression stockings, and braces. You need a prescription or doctor's order for most of these items, and you should keep that documentation in case your FSA plan asks for proof.
Certain items sit in a gray area. Sunscreen is not may be able to access (it is preventive, not treatment). Pregnancy tests are may be able to access. Condoms are not. If you are unsure, ask your FSA plan administrator before you buy — they can tell you whether a specific item qualifies, and getting that answer in writing protects you if there is a dispute later.
What does not count: insurance, cosmetics, and wellness
You cannot use FSA money to pay insurance premiums — not health insurance, dental insurance, or vision insurance. You also cannot pay for cosmetic procedures, even if a doctor performs them. Botox, teeth whitening, and hair removal do not count unless they are medically necessary (for example, hair removal prescribed to treat a skin condition).
Vitamins, supplements, and general wellness items are not may be able to access, even if they are sold at a pharmacy. Gym memberships and fitness classes do not count. Sunscreen, toothpaste, and soap are not medical expenses. Weight-loss programs are not covered unless they treat a specific medical condition like obesity-related diabetes, and even then you need documentation from your doctor.
How to track and submit FSA expenses
Most employers issue an FSA debit card that you can use at pharmacies, doctors' offices, and medical suppliers. When you swipe the card, the transaction is usually approved automatically if the merchant is coded as a medical provider. Keep your receipt anyway — your FSA plan may ask for proof that the expense was medical.
If you pay out of pocket, submit a receipt and an explanation-of-benefits statement (if your insurance was involved) to your FSA plan for reimbursement. The process usually takes one to two weeks. Some plans let you submit online through a portal or app; others require paper forms mailed to an address. Check your plan documents to find out which method your employer uses.
Save all receipts and documentation for at least three years. If your FSA plan audits a claim, you will need proof that the expense was real and that it qualifies. A receipt alone is usually enough, but for gray-area items, a doctor's note is safer.
Frequently Asked Questions
Can I use my FSA to pay for my spouse's or child's medical expenses?
Yes, as long as they are your dependents for tax purposes. You can use your FSA to cover medical expenses for your spouse and any children you claim on your tax return. The expense does not have to be incurred by you — it just has to be a may have access to medical expense for someone in your household.
What happens if I do not spend all my FSA money by the end of the year?
Most of it is forfeited — you lose the unspent balance. Some employers offer a grace period (usually until March 15 of the next year) or allow you to carry over up to $640 to the next year, but this is optional and not all plans include it. Check your plan documents to see what your employer offers. If neither option is available, you should estimate conservatively when you choose your contribution amount.
Can I use FSA money for telehealth visits?
Yes. Telehealth copays and the cost of virtual visits count as FSA-may be able to access medical expenses. You can use your FSA debit card or submit a receipt for reimbursement, just as you would for an in-person visit.
Do I need a prescription for FSA-may be able to access medical equipment like a heating pad or ice pack?
It depends on the item and your plan. Some medical equipment requires a prescription; some does not. A heating pad or ice pack used for general comfort is usually not may be able to access, but one prescribed by a doctor for a specific condition may be. Ask your FSA plan administrator or your doctor before you buy.
Can I use FSA money for my pet's medical expenses?
No. FSA funds cover medical expenses for you and your tax dependents only. Veterinary care does not count, even if your pet is a service animal. (Service animals themselves may may have access to under certain circumstances, but routine veterinary care does not.)
