A flexible spending account (FSA) covers medical costs you pay out of your own pocket, but only specific ones

Your FSA money can pay for doctor visits, prescription drugs, dental work, vision care, and medical equipment — but not groceries, gym memberships, or over-the-counter vitamins without a prescription. The IRS maintains a list of what counts as a medical expense, and it is narrower than "anything health-related." The key rule: the expense must treat or prevent a diagnosed medical condition, and you must have a prescription or doctor's order for it.

Because FSA rules are strict, many people waste money by guessing wrong. This guide walks through what actually qualifies, what does not, and how to avoid losing unspent funds at the end of the year.

Key Takeaways

  • Doctor visits, prescriptions, dental work, and vision care all may have access to, but only if you pay for them yourself — not if insurance covers them.
  • Over-the-counter items like pain relievers, allergy medicine, and cold medicine require a prescription from your doctor to count as FSA expenses.
  • Gym memberships, vitamins, cosmetic procedures, and weight-loss programs do not may have access to, even if they improve your health.
  • You must spend FSA money by the end of the plan year or lose it — there is no rollover — so track what you spend and plan ahead.

Medical visits and prescriptions you pay for yourself

Doctor office visits, urgent care, and emergency room copays all count. So do prescription medications your doctor writes for you. The expense has to come out of your pocket — if your insurance pays it, you cannot use FSA money to reimburse yourself.

Mental health visits, including therapy and psychiatry appointments, may have access to. So do lab tests and imaging (X-rays, ultrasounds, MRIs) when ordered by a doctor. If you pay a deductible before insurance kicks in, that deductible counts as an FSA expense.

Prescription inhalers, insulin, and other maintenance medications all may have access to. Over-the-counter versions of the same drug do not — for example, over-the-counter ibuprofen does not count, but prescription-strength ibuprofen does.

Dental and vision care

Dental cleanings, fillings, root canals, crowns, and orthodontia (braces) all count. So do dentures and dental implants. You do not need a separate dental plan to use FSA money for these — you can pay out of pocket and use your FSA to cover it.

Vision care includes eye exams, glasses, contact lenses, and contact lens solution. Laser eye surgery (LASIK) also qualifies. Like dental work, you can use FSA money even if you do not have vision insurance.

Medical equipment and supplies

Crutches, wheelchairs, hearing aids, and blood pressure monitors count. So do diabetic supplies (test strips, lancets, glucose meters), bandages, and medical tape. Prescription orthotics (custom shoe inserts) may have access to, but over-the-counter arch supports do not.

Pregnancy tests, ovulation kits, and contraceptive devices like IUDs count as FSA expenses. So do breast pumps and pump supplies. Medical alert systems and devices that monitor a diagnosed condition also may have access to.

One common mistake: elastic bandages and over-the-counter pain relief patches do not count unless prescribed. But if your doctor writes an order for them, they do.

Over-the-counter medicines and when they may have access to

This is where FSA rules trip people up. Over-the-counter pain relievers, allergy medicine, cold medicine, antacids, and laxatives do not count — unless your doctor writes a prescription for them. A prescription for ibuprofen or diphenhydramine (Benadryl) makes it FSA-may be able to access, but buying the same product off the shelf does not.

The rule applies even to common items. Aspirin does not count. Cough syrup does not count. Antihistamines do not count. But if your doctor prescribes any of these, you can use FSA money.

Vitamins and supplements do not count, even with a prescription, unless they treat a specific diagnosed deficiency (like iron supplements for anemia). Multivitamins do not count under any circumstance.

What does not count, even if it helps your health

Gym memberships, fitness classes, and sports equipment do not count, even if your doctor recommends exercise. Weight-loss programs and diet supplements do not count. Cosmetic procedures — including teeth whitening, Botox, and hair removal — do not count.

Sunscreen, toothpaste, and soap do not count, even though they prevent disease. Maternity clothes do not count. Childcare does not count. Travel to a medical appointment does not count (though the medical appointment itself does).

Marijuana, even in states where it is legal and even with a doctor's recommendation, does not count as an FSA expense under federal law. Acupuncture does count if ordered by a doctor for a diagnosed condition.

How to track spending and avoid losing money

FSA money does not roll over. Whatever you do not spend by December 31 (or your plan's end date) is gone — your employer keeps it. This is called the "use-it-or-lose-it" rule, and it is why planning matters.

Keep receipts and invoices for everything you buy with FSA money. Your plan administrator may ask for proof that an expense qualifies. Many FSA debit cards flag purchases that might not count, and you will need documentation to override the flag.

If you are unsure whether something counts, ask your plan administrator before you buy it. Most plans have a customer service line and a website with a searchable list of approved expenses. Asking takes five minutes; losing the money takes a year to regret.

At the start of each year, estimate what you will spend on medical, dental, and vision care that your insurance will not cover. That number is what you should contribute to your FSA. If you overestimate and have money left over, you cannot get it back.

Frequently Asked Questions

Can I use FSA money for my spouse or children?

Yes. FSA money covers medical expenses for you, your spouse, and any dependent children, even if they are not on your health insurance plan. You can use it for their doctor visits, prescriptions, dental work, and other covered expenses.

Does my insurance have to deny a claim before I can use FSA money?

No. You can use FSA money for any covered expense you pay out of pocket, whether insurance covers it or not. If insurance pays part and you owe a copay or coinsurance, you can use FSA for your share.

What happens if I buy something and later find out it does not count?

You cannot get reimbursed from your FSA. If you submit a receipt for a non-covered item, the plan will deny it. This is why checking before you buy is important — once you spend your own money, you cannot undo it.

Can I use FSA money for preventive care my insurance covers for free?

No. If your insurance covers a service at no cost to you (like annual physicals or cancer screenings), you cannot use FSA money for it. FSA covers only expenses you actually pay.

What if I change jobs mid-year?

You lose access to your FSA when you leave your job, even if you have money left in it. Some plans allow you to continue coverage under COBRA, but you pay the full premium yourself. Check with your plan administrator about your options before you leave.
