What Your Flex Spending Account Can Actually Pay For

Your FSA covers medical, dental, and vision expenses that your insurance doesn't

A Flexible Spending Account (FSA) lets you set aside pre-tax money to pay 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 paid from your FSA without tax penalties. The list is longer than most people think — it includes things beyond doctor visits and prescriptions — but it has real limits.

The key rule: your FSA can only pay for expenses that treat or prevent a medical condition. Cosmetic procedures, general wellness products, and over-the-counter items without a prescription are out. But if your doctor says you need it for a medical reason, there is a good chance your FSA can cover it.

Key Takeaways

• FSA funds cover doctor visits, hospital care, prescription medications, and most medical equipment your doctor prescribes.
• Dental work (cleanings, fillings, root canals, orthodontics) and vision care (exams, glasses, contacts, surgery) are covered if you have a dependent care FSA or a health care FSA that includes them.
• Over-the-counter medicines and first aid supplies now require a prescription from your doctor to be FSA-may be able to access, even common items like pain relievers and allergy medicine.
• Gym memberships, vitamins, cosmetic procedures, and weight loss programs are not covered, even if they improve your health.
• You must use FSA money within the plan year or lose it — there is no rollover, though some plans offer a short grace period.

Medical care and prescriptions your FSA will pay for

Your FSA covers the full cost of doctor visits, including copays and coinsurance. This includes visits to your primary care doctor, specialists, urgent care clinics, and emergency rooms. If your insurance requires you to pay a portion of the bill, your FSA can cover that portion.

Prescription medications are covered in full. Over-the-counter drugs — aspirin, cold medicine, allergy tablets, antacids — now require a prescription to be FSA-may be able to access. If your doctor writes a prescription for an over-the-counter medication, your FSA can pay for it. Without a prescription, it cannot. This rule changed in 2020 and catches many people off guard.

Hospital stays, surgery, and lab tests are all covered. If you need imaging (X-rays, MRI, CT scans), your FSA pays for it. Mental health care, including therapy and psychiatric visits, is covered. Substance abuse treatment is covered. Dental work done in a hospital setting is covered.

Dental and vision expenses covered by FSA

Routine dental care — cleanings, exams, and X-rays — is FSA-may be able to access. Fillings, root canals, crowns, and extractions are covered. Orthodontic work, including braces and retainers, is covered. Dentures and dental implants are covered. Teeth whitening is not covered because it is considered cosmetic, not medically necessary.

Vision exams are covered. Eyeglasses and contact lenses are covered, including the cost of the lenses and frames. Contact lens solution is covered. LASIK and other vision correction surgery is covered. Sunglasses are not covered, even if you have a light sensitivity condition, because they are not prescribed medical devices.

Medical equipment and supplies your FSA can pay for

Durable medical equipment prescribed by your doctor is covered. This includes wheelchairs, crutches, walkers, hearing aids, and blood pressure monitors. Diabetic supplies — test strips, lancets, and glucose meters — are covered. Bandages, gauze, and other wound care supplies are covered if they are for treating an injury or medical condition.

Elastic bandages and braces are covered. Heating pads and ice packs are covered. Canes and other mobility aids are covered. Compression stockings prescribed for a medical condition are covered. Pregnancy test kits are covered. Thermometers are covered.

Prosthetics and orthotics are covered. If your doctor prescribes a back brace, knee brace, or other orthotic device, your FSA pays for it. Wigs needed because of hair loss from a medical condition (such as chemotherapy) are covered.

What your FSA cannot pay for

Cosmetic procedures are not covered, even if they make you feel better. This includes teeth whitening, hair removal, and cosmetic surgery. Gym memberships and fitness classes are not covered, even if your doctor recommends exercise. Weight loss programs and diet plans are not covered. Vitamins and nutritional supplements are not covered unless prescribed by your doctor for a specific medical deficiency.

General wellness products — air purifiers, humidifiers, massage chairs — are not covered. Sunscreen is not covered. Toothpaste and mouthwash are not covered. Deodorant is not covered. Shampoo and conditioner are not covered, even medicated versions, unless prescribed by a dermatologist for a specific scalp condition.

Cosmetic dental work like teeth whitening or veneers is not covered. Cosmetic eyewear like designer frames chosen purely for style is not covered, though you can use FSA funds for the medical portion of prescription glasses. Maternity clothes are not covered. Childcare is not covered by a health care FSA (though a dependent care FSA is a separate account type that does cover childcare).

How to know if something is FSA-may be able to access before you buy

The IRS publishes a list of may have access to medical expenses in Publication 502. Your FSA plan administrator also publishes a list of covered items specific to your plan — some plans are more restrictive than the IRS allows. Before you buy something you think might be covered, check your plan's documentation or call your plan administrator's customer service line.

When in doubt, ask your doctor. If your doctor prescribes something or states in writing that it is medically necessary for your condition, that written statement often makes the item FSA-may be able to access. Keep receipts and any documentation from your doctor. If your FSA denies a claim, you can appeal with proof that the item was medically necessary.

Some items sit in a gray area. For example, a standing desk might be covered if your doctor prescribes it for a back condition, but not if you buy it for general wellness. A humidifier might be covered if prescribed for asthma or allergies, but not for general comfort. The deciding factor is usually whether a doctor prescribed it or stated it was medically necessary in writing.

The use-it-or-lose-it rule and how to plan spending

FSA money must be used in the plan year it was set aside for. If you do not spend it by December 31 (or the end of your plan year if your employer uses a different calendar), you lose it. There is no rollover to the next year, and you cannot get a refund. This is the biggest limitation of an FSA compared to other savings accounts.

Some employers offer a grace period of up to 2.5 months into the next year to spend the previous year's money. Some employers offer a carryover of up to $610 (the amount changes yearly) to the next plan year. Check your plan documents to see if either applies to you. If neither does, you need to estimate your medical expenses carefully and set aside only what you think you will actually spend.

Common strategies: review your medical history from the past year, add up what you spent out of pocket, and set aside roughly that amount. If you wear contacts, buy a year's supply in December. If you need glasses, get them before the year ends. Schedule dental cleanings and vision exams before the plan year closes. If you have predictable medical expenses (medications, therapy, medical equipment), front-load your FSA contributions early in the year.

Frequently Asked Questions

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

Yes, if they are covered under your health insurance plan. You can use your FSA to pay for out-of-pocket costs for any family member covered by your plan. If your spouse or child has their own insurance, you cannot use your FSA for their expenses.

Does my FSA cover over-the-counter pain relievers if I don't have a prescription?

No. As of 2020, over-the-counter medications including pain relievers, cold medicine, allergy tablets, and antacids require a prescription from your doctor to be FSA-may be able to access. Ask your doctor to write a prescription if you use these regularly, and your FSA can then pay for them.

What happens to my FSA money if I don't spend it by the end of the year?

You lose it. FSA funds do not roll over to the next year unless your employer's plan specifically allows a carryover (usually up to $610) or a grace period (usually 2.5 months). Check your plan documents to see which applies to you. This is why estimating your medical expenses carefully is important.

Can I use my FSA to pay for my gym membership if my doctor recommends exercise?

No. Gym memberships and fitness classes are not FSA-may be able to access, even with a doctor's recommendation. However, if your doctor prescribes physical therapy for an injury or condition, your FSA covers that.

Are prescription glasses and contacts covered by FSA?

Yes. Prescription eyeglasses, contact lenses, and contact lens solution are all FSA-may be able to access. Vision exams are covered. LASIK and other vision correction surgery is covered. The frames and lenses must be prescribed by an eye doctor.
