FSA funds cover medical expenses your insurance doesn't, but only specific ones
A Flexible Spending Account (FSA) lets you set aside pre-tax money for out-of-pocket medical costs. The catch is that you can only spend it on things the IRS classifies as may have access to medical expenses. That means some things you might assume are covered — like over-the-counter pain relievers or vitamins — actually aren't, unless you have a doctor's prescription for them.
The IRS publishes a list of what counts. It's long, but the basic rule is simple: if it's primarily for treating or preventing a diagnosed medical condition, and it's not something your insurance already covers, you can probably use FSA money for it. If it's for general wellness or beauty, you can't.
Your FSA plan document may be stricter than the IRS rules, so check with your plan administrator before you spend. Some employers add their own limits on top of federal rules.
Key Takeaways
- Prescription medications, copays, and deductibles are always FSA-may be able to access, whether your insurance covers them or not.
- Over-the-counter drugs like ibuprofen, allergy medicine, and cold medicine require a doctor's prescription to be FSA-may be able to access.
- Medical equipment like crutches, wheelchairs, and blood pressure monitors counts, but cosmetic items like sunscreen and toothpaste do not.
- Dental work, vision care, and mental health treatment are covered if you pay out-of-pocket, but check your plan first because some employers exclude them.
- Your FSA money expires at the end of the plan year, so you lose what you don't spend — plan your contributions carefully.
Prescription medications and pharmacy costs
Any prescription medication your doctor writes is FSA-may be able to access, regardless of what it treats. That includes birth control, psychiatric medications, antibiotics, and maintenance drugs for chronic conditions. You can use your FSA debit card at the pharmacy counter, or you can pay out of pocket and submit a receipt for reimbursement later.
Insulin and other diabetes supplies — test strips, lancets, and glucose monitors — are covered. Inhalers for asthma, EpiPens, and epinephrine auto-injectors all count. If your doctor prescribed it and a pharmacy filled it, your FSA covers it.
The pharmacy doesn't need to know you're using FSA money. Just present your FSA debit card like you would any other payment method. If the pharmacy's system rejects it, call your FSA plan administrator to confirm the medication is may be able to access under your specific plan.
Over-the-counter drugs and supplies (with a prescription)
This is where many people get stuck. Ibuprofen, acetaminophen, allergy medicine, antacids, and cold medicine are not FSA-may be able to access just because you bought them at a drugstore. You need a doctor's prescription for them first.
If your doctor writes a prescription for ibuprofen, Claritin, or Tums — even though you could buy the same thing without a prescription — then your FSA covers it. The prescription is what makes it a medical expense rather than a consumer product. Some doctors will write these prescriptions if you ask, especially if you have a chronic condition that requires regular use.
Bandages, gauze, medical tape, and first-aid supplies are FSA-may be able to access without a prescription because they're medical equipment, not drugs. The same goes for heating pads, ice packs, and elastic bandages.
Medical equipment and devices
Crutches, wheelchairs, walkers, canes, and other mobility aids are FSA-may be able to access. So are blood pressure monitors, thermometers, pulse oximeters, and other diagnostic devices you use at home. Hearing aids and batteries for hearing aids count. Orthopedic braces, back supports, and compression sleeves are covered if they treat a specific condition.
CPAP machines and supplies for sleep apnea are may be able to access. Continuous glucose monitors and insulin pumps for diabetes are covered. Nebulizers, peak flow meters, and spacers for asthma are all on the list.
The rule is that the device must be primarily medical — it has to treat or manage a health condition, not just make life more comfortable. A regular pillow isn't may be able to access, but a cervical pillow prescribed by a doctor for neck pain might be, depending on your plan.
Dental, vision, and mental health care
Dental work is FSA-may be able to access: cleanings, fillings, root canals, crowns, extractions, and orthodontia all count. You can use your FSA to pay your dentist's bill directly, or submit receipts for reimbursement. The same applies to vision care — eye exams, glasses, contact lenses, and contact lens solution are all covered.
Mental health treatment is may be able to access too. Therapy sessions, psychiatry appointments, and counseling are FSA-covered expenses. If you pay a therapist out of pocket, you can submit the receipt for reimbursement.
However, some employer plans exclude dental or vision coverage entirely, even though the IRS allows it. Check your plan document before you count on these expenses. If your plan excludes them, you cannot use FSA money for them, even though other plans do.
What is not covered, even if it seems medical
Cosmetic procedures are never FSA-may be able to access, even if a doctor performs them. That includes teeth whitening, Botox, hair removal, and cosmetic surgery. The exception is if the procedure is reconstructive — fixing a birth defect, repairing an injury, or treating a disease — rather than purely cosmetic.
General wellness items are not covered. Vitamins, supplements, and herbal products are not FSA-may be able to access unless a doctor prescribes them for a specific deficiency or condition. Sunscreen, toothpaste, deodorant, and shampoo are not may be able to access, even medicated versions, because they're personal care items rather than treatment for a diagnosed condition.
Gym memberships, fitness classes, and weight loss programs are not covered, even if your doctor recommends exercise. Maternity clothes, diapers, and baby formula are not may be able to access. Over-the-counter pain relievers, allergy medicine, and cold medicine without a prescription are not covered, as noted above.
How to know if something is covered before you spend
Your FSA plan administrator maintains a list of may be able to access expenses specific to your plan. Call them or check your plan's website before you make a purchase. Many plans have searchable databases where you can type in a product name or medical condition and get an answer.
If you're unsure, ask your doctor. If the expense is for treating a diagnosed condition and your doctor confirms it's medically necessary, there's a good chance it's may be able to access. Keep the receipt and your doctor's note together — if the FSA denies reimbursement, you'll need proof of the medical reason.
When you use your FSA debit card at a pharmacy or medical office, the system usually knows whether the item is may be able to access. If the card is declined, that's a sign the expense isn't covered under your plan. Don't assume it will be covered just because a similar item worked before — different brands, formulations, and product types have different rules.
Frequently Asked Questions
Can I use my FSA for my spouse or children?
Yes. Your FSA covers may have access to medical expenses for you, your spouse, and any dependent children, regardless of whether they're on your insurance plan. You can submit receipts for their medical costs and get reimbursed from your FSA account.
What happens if I buy something and it turns out not to be FSA-may be able to access?
You pay for it out of pocket and cannot get reimbursed from your FSA. The FSA administrator will deny the reimbursement request. Keep your receipts so you know what you've already submitted, and check the may be able to access list before you buy something expensive.
Can I use my FSA for medical expenses my insurance already paid for?
No. FSA money is for out-of-pocket costs — copays, deductibles, and expenses your insurance doesn't cover. You cannot use it to reimburse yourself for something your insurance already paid.
Are prescription glasses and contacts covered if I don't have vision insurance?
Yes, as long as your FSA plan includes vision coverage. Check your plan document, because some employers exclude vision and dental even though the IRS allows them. If your plan covers vision, you can use FSA money for exams, glasses, contacts, and solution.
Can I use my FSA for a doctor's visit copay?
Yes. Copays for any doctor visit — primary care, specialist, urgent care, or emergency room — are FSA-may be able to access. You can use your FSA debit card at the time of the visit, or submit the receipt later for reimbursement.
