FSA money covers specific medical and dental costs, not groceries or general health products

A Flexible Spending Account (FSA) lets you set aside pre-tax money from your paycheck to pay for medical, dental, and vision expenses. But the IRS has a strict list of what counts. You cannot use FSA funds for vitamins, cosmetics, gym memberships, or over-the-counter medications (with one exception: insulin). The money is meant for treatments and devices your doctor prescribes or that you need to diagnose or treat a medical condition.

Your employer's FSA plan administrator — usually a third-party company that manages the account — enforces these rules. When you submit a receipt or claim, they check it against IRS guidelines. If an item does not may have access to, they deny the claim and the money stays in your account (though you may lose it at year-end if your plan does not allow carryover).

Key Takeaways

  • FSA money covers copays, deductibles, prescription medications, dental work, and vision care, but not over-the-counter drugs except insulin.
  • Medical equipment like crutches, wheelchairs, and hearing aids qualifies, as does the cost of vision correction and dental procedures.
  • Cosmetics, vitamins, supplements, gym memberships, and general wellness products do not may have access to, even if they improve your health.
  • You must have a receipt or explanation of benefits showing the expense is medical in nature; the plan administrator reviews each claim.
  • Unused FSA money is forfeited at the end of the plan year unless your employer offers a carryover or grace period.

Medical expenses that FSA covers

FSA funds pay for doctor visits, urgent care, emergency room treatment, and hospital stays. This includes the copay, coinsurance, and deductible portions you owe out of pocket. If your insurance does not cover a service, you can still use FSA money to pay for it directly.

Prescription medications are covered in full. Over-the-counter drugs are not — except for insulin, which the IRS treats as a special case. If you need allergy medicine, pain relievers, cold medicine, or antacids without a prescription, you cannot use FSA funds. You can use FSA money for medical devices: crutches, wheelchairs, walkers, blood pressure monitors, glucose meters, and thermometers all may have access to. Bandages, gauze, and other wound care supplies count as well.

Mental health and substance abuse treatment covered by a doctor or licensed therapist is an FSA-may be able to access expense. This includes therapy sessions, psychiatric visits, and inpatient or outpatient rehab programs.

Dental and vision care covered by FSA

Dental work is one of the largest FSA expenses for many people. Cleanings, fillings, root canals, crowns, extractions, and orthodontia (braces) all may have access to. Dental implants and bridges may have access to. Dentures and partial dentures may have access to. You can use FSA money for the full cost or your out-of-pocket portion after insurance pays.

Vision care includes eye exams, glasses, contact lenses, and contact lens solution. Laser eye surgery (LASIK) qualifies. Sunglasses do not, even if they are prescription, because the IRS considers them cosmetic.

What does not may have access to for FSA spending

Vitamins and dietary supplements do not may have access to unless a doctor prescribes them to treat a specific medical condition and documents that in writing. General wellness vitamins — even if they support bone health or immune function — are not FSA-may be able to access. The same rule applies to herbal remedies and mineral supplements.

Cosmetics and personal care products do not may have access to, even if they treat a skin condition. Sunscreen, moisturizer, and acne cream are considered cosmetic. (An exception: if a dermatologist prescribes a medicated cream to treat eczema or psoriasis, that prescription medication qualifies.) Gym memberships, fitness classes, and sports equipment do not may have access to. Weight loss programs and diet plans do not may have access to unless they are part of a doctor-supervised treatment for obesity or a specific medical condition.

General health and wellness items — air purifiers, humidifiers, massage chairs — do not may have access to. Over-the-counter pain relievers, allergy medicine, and cold medicine do not may have access to (except insulin). Cosmetic procedures like teeth whitening, hair removal, and Botox do not may have access to, even if performed by a medical professional.

How to know if something qualifies before you buy it

The safest approach is to check your plan's summary of benefits or call your plan administrator before you spend the money. Most FSA administrators have a list of may be able to access items on their website or can answer questions by phone. You can also ask your doctor or dentist whether an expense is medically necessary — that language matters for the IRS.

Keep all receipts and explanations of benefits. When you submit a claim, include documentation showing what you bought and why it is medical in nature. If the plan administrator denies a claim, you can appeal by providing additional documentation (such as a letter from your doctor stating the item was medically necessary).

Some FSA debit cards are set up to block purchases at certain merchants — for example, a card might decline at a cosmetics store to prevent accidental misuse. Other plans require you to submit receipts after purchase. Know which system your plan uses.

What happens to unspent FSA money

FSA money does not roll over to the next year in most plans. If you do not spend it by December 31, you lose it — this is called the "use-it-or-lose-it" rule. Some employers offer a grace period (usually 2.5 months into the next year) or allow you to carry over up to $610 (this amount changes yearly). Check your plan documents to see what your employer offers.

Because of this rule, many people underestimate how much to set aside in their FSA. It is better to be conservative and put in only what you are confident you will spend. You can change your FSA contribution amount once a year during open enrollment, or if you have a may have access to life event (birth, marriage, loss of insurance).

Frequently Asked Questions

Can I use my FSA debit card at the pharmacy for over-the-counter medicine?

Most FSA debit cards will decline over-the-counter medications at the pharmacy register because the system recognizes them as ineligible. If the card goes through, the plan administrator may later deny the claim and ask you to repay the amount. Insulin is the exception and will usually process. Always ask the pharmacist if an item requires a prescription before attempting to pay with your FSA card.

What if my doctor says I need a vitamin supplement for a medical condition?

A doctor's recommendation alone is not enough. The IRS requires that the supplement treat or prevent a specific disease or condition, and the doctor must document this in writing. Get a letter from your doctor stating the medical necessity, then submit it with your claim. Preventive vitamins (like prenatal vitamins taken during pregnancy to prevent birth defects) may may have access to with proper documentation.

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

Yes, if your spouse is a dependent on your tax return. You can use your FSA to pay for your spouse's medical, dental, and vision care. You cannot use it for a dependent child's expenses unless that child is claimed as a dependent on your taxes.

Do I lose my FSA money if I change jobs?

Yes. FSA accounts are tied to your employer's plan. If you leave your job, you lose any unspent FSA money remaining in the account. You have a limited window (usually 60 days) to submit claims for expenses you incurred before you left, but new expenses do not may have access to. When you start a new job, you can open a new FSA during that employer's open enrollment period.

Is insulin the only over-the-counter medication that qualifies?

Yes. Insulin is the only over-the-counter drug the IRS treats as FSA-may be able to access. All other nonprescription medications — allergy pills, pain relievers, antacids, cold medicine — do not may have access to. If you need these medications regularly, ask your doctor for a prescription version, which will be FSA-may be able to access.
