What You Can Actually Buy With a Flexible Spending Account

A Flexible Spending Account covers medical, dental, and vision expenses your insurance doesn't fully pay for

A Flexible Spending Account (FSA) lets you set aside pre-tax money for out-of-pocket health care costs. The IRS maintains a specific list of what counts as a may have access to medical expense, and only those items can be purchased with FSA funds. The list is longer than most people expect — it includes things beyond just doctor visits — but it has real limits. You cannot use FSA money for cosmetic procedures, over-the-counter medications (with one exception), or health-related items that are not medical in nature.

The key rule: the expense must be for diagnosis, treatment, or prevention of a disease or condition, and it must not be something that improves general health or appearance without treating a specific medical problem. That distinction matters because it determines whether you can reimburse yourself from your FSA or whether the money stays locked in your account.

Key Takeaways

• FSA funds cover copays, coinsurance, deductibles, and the full cost of services your insurance does not cover at all.
• Prescription medications, insulin, and most medical equipment and supplies are covered, but over-the-counter drugs are not unless they are insulin.
• Dental work, vision care, and hearing aids are covered FSA expenses, even if your insurance does not include dental or vision coverage.
• Cosmetic procedures, gym memberships, vitamins, and general wellness products are not covered, even if they improve your health.
• You must have a receipt or explanation of benefits from your provider to reimburse yourself; the FSA administrator will not pay based on your word alone.

Medical expenses your insurance leaves you to pay

The most straightforward FSA use is paying the portions of medical bills that your insurance plan does not cover. This includes copays (the flat fee you pay at a doctor's visit), coinsurance (your percentage of the cost after insurance pays its share), and deductibles (the amount you must pay before insurance kicks in). If your plan has a $1,500 deductible and you meet it through several doctor visits and lab work, you can reimburse yourself from your FSA for that full $1,500.

FSA money also covers the entire cost of services your insurance does not cover at all. If your plan does not include mental health visits, for example, you can use FSA funds to pay an out-of-network therapist. If your insurance does not cover a particular medication or treatment, the FSA can cover it. The expense still has to be medically necessary — ordered or recommended by a doctor — but the insurance gap is not a barrier.

Prescription and over-the-counter medications

Prescription medications are always a covered FSA expense. Insulin is the only over-the-counter medication that qualifies. All other over-the-counter drugs — including pain relievers, cold medicines, allergy medications, and antacids — cannot be purchased with FSA funds, even if a doctor recommends them. This rule changed in 2011 and remains in effect.

The exception is narrow: if you have a prescription for an over-the-counter medication (meaning your doctor wrote a prescription rather than just recommending you buy it), that prescription version may be covered. But a prescription for ibuprofen is rare in practice. The simpler approach is to use FSA money for prescription versions of medications when they exist, or to pay for over-the-counter drugs out of pocket.

Dental and vision care

Dental expenses are covered FSA costs, whether or not your insurance includes dental coverage. Cleanings, fillings, root canals, crowns, orthodontia, and tooth extractions all count. If you have dental insurance, you use your FSA to cover the copays and coinsurance. If you do not have dental insurance, you can use FSA funds to pay the full cost of dental work.

Vision care works the same way. Eye exams, glasses, contact lenses, and contact lens solution are all covered. If your insurance includes vision coverage, the FSA covers your out-of-pocket costs. If it does not, the FSA covers the full bill. Laser eye surgery (LASIK or PRK) is also a covered expense, as is the cost of corrective lenses prescribed after the surgery.

Medical equipment and supplies

FSA funds cover a wide range of medical equipment and supplies used to treat a diagnosed condition. Crutches, wheelchairs, walkers, and canes are covered. Blood glucose monitors and test strips for diabetes are covered. Hearing aids and hearing aid batteries are covered. Orthopedic braces, compression stockings, and other medical supports are covered. Bandages, gauze, and other wound care supplies are covered.

The rule is that the item must be primarily medical in nature and used to treat or manage a specific condition. A blood pressure monitor is covered because it is used to monitor a diagnosed condition. A general fitness tracker is not covered, even if it can measure heart rate, because it is designed for general wellness rather than treatment of a specific disease. If you are uncertain whether a particular item qualifies, ask your FSA administrator before you buy it — they can tell you whether a receipt will be reimbursable.

Services and treatments that do not may have access to

Cosmetic procedures are not covered, even if they are performed by a medical professional. Botox, dermal fillers, hair removal, teeth whitening, and cosmetic surgery do not count as FSA expenses. The exception is if the procedure is reconstructive rather than cosmetic — for example, surgery to repair a deviated septum that impairs breathing is covered, but surgery to reshape your nose for appearance alone is not.

Gym memberships, fitness classes, and general wellness programs are not covered, even if your doctor recommends exercise. Vitamins, supplements, and herbal products are not covered unless they are prescribed by a doctor to treat a specific medical condition (which is rare). Weight loss programs and diet plans are not covered. Sunscreen is not covered. These items improve health or prevent disease in a general sense, but they do not treat a diagnosed condition, so they fall outside the FSA rules.

How to document and reimburse yourself

When you use your FSA debit card to pay a provider, the transaction is usually documented automatically — the provider sends the claim information to your FSA administrator. But if you pay out of pocket and want to reimburse yourself, you must submit a receipt or explanation of benefits from the provider. The FSA administrator will not reimburse you based on your description of the expense or a credit card statement alone.

Keep receipts for all FSA expenses, even small ones. If you pay $30 for a copay and later need to prove it, you will need the receipt from the doctor's office. Many FSA administrators allow you to submit receipts through a mobile app or online portal, which makes the process faster. Some administrators also offer a debit card that works like a credit card at medical providers, which eliminates the need to submit receipts for those transactions.

Frequently Asked Questions

Can I use my FSA to pay for my spouse's or child's medical expenses?

Yes. FSA funds can be used for any family member you claim as a dependent on your tax return, plus your spouse even if they are not a dependent. You do not need to be on the same insurance plan. Keep receipts in the name of the person who received the care, not your own name.

What happens if I buy something with my FSA and later find out it is not covered?

If you use your FSA debit card and the provider submits a claim that the FSA administrator denies, you will be responsible for paying the full amount. If you paid out of pocket and submitted a receipt for reimbursement, the administrator will deny the reimbursement request. Either way, the money is gone. This is why it is worth checking with your administrator before you buy expensive items.

Can I use FSA money for travel to a medical appointment?

No. Travel costs — gas, flights, hotels, or meals — are not covered FSA expenses, even if you are traveling for a medical procedure. Only the medical service itself is covered. Parking at a hospital or medical office is also not covered.

Are mental health and therapy visits covered?

Yes. Therapy, counseling, and psychiatric visits are covered FSA expenses. If your insurance includes mental health coverage, you use your FSA to pay your copay or coinsurance. If your insurance does not cover mental health, you can use FSA funds to pay an out-of-network therapist in full.

Can I use my FSA for pet medical expenses?

No. Veterinary care and pet medications are not covered, even if the pet is a service animal. Service animals themselves (the cost of training or purchasing one) are also not covered. Only human medical expenses count.
