You can use your HSA for medical expenses you pay out of your pocket, and for some costs insurance won't cover

A Health Savings Account (HSA) is designed to pay for healthcare costs — but not every healthcare cost. The IRS has a specific list of what counts. The basic rule: if it's a medical expense your insurance doesn't cover, and a doctor would reasonably say it's necessary to treat or prevent illness or injury, you can probably use HSA money for it.

The tricky part is that "medical expense" includes things that sound like they shouldn't count — like certain vitamins, some dental work, and even some equipment you buy at a drugstore. At the same time, it excludes things that sound medical but aren't on the list, like cosmetic procedures or gym memberships (even if your doctor says exercise would help you).

The money in your HSA is yours to keep. You don't lose it at the end of the year. That means you can save it for years and use it whenever you need to, which makes it different from a Flexible Spending Account (FSA), where unused money typically goes back to your employer.

Key Takeaways

  • You can use HSA money for deductibles, copays, coinsurance, and any medical cost your insurance doesn't cover.
  • Prescription medications, dental work, vision care, and mental health treatment all count as HSA-may be able to access expenses.
  • Some over-the-counter items like pain relievers, allergy medicine, and bandages count, but only if you have a prescription or doctor's note for them.
  • Cosmetic procedures, gym memberships, and general wellness products do not count, even if they improve your health.
  • You keep unused HSA money year to year, so you can save it for future medical costs or retirement.

Medical expenses your insurance requires you to pay

The most straightforward HSA use is paying the costs your insurance plan makes you responsible for. This includes your deductible (the amount you pay before insurance kicks in), your copay (a flat fee per visit), and your coinsurance (a percentage of the cost you split with insurance).

If your insurance plan has a $1,500 deductible and you go to the doctor, you pay that $1,500 out of pocket first. You can use HSA money for it. If you have a $30 copay for each visit, HSA money covers that too. The same applies to the percentage you owe after insurance pays its share.

This is why HSAs pair well with high-deductible health plans — the plans that require you to pay more upfront. The HSA gives you a tax-advantaged way to set aside money for those costs.

Prescription and over-the-counter medications

Prescription medications are always HSA-may be able to access, no matter what they treat. Insulin, blood pressure pills, antibiotics, antidepressants — all of them count.

Over-the-counter medications are trickier. You can use HSA money for them, but only if you have a prescription or written order from a doctor. This means you can't just buy ibuprofen or allergy medicine off the shelf with your HSA debit card. You need your doctor to write a prescription for it first, even though the medication itself doesn't require a prescription to purchase.

The exception: insulin. You can buy insulin over the counter with HSA money without a prescription, because the IRS treats it differently from other over-the-counter drugs.

Dental, vision, and hearing care

Dental work counts as an HSA expense. This includes cleanings, fillings, root canals, crowns, and orthodontia like braces. If your dental insurance doesn't cover it, or if you don't have dental insurance, HSA money can pay for it.

Vision care is also covered. Eye exams, glasses, contact lenses, and surgery to correct vision (like LASIK) all count. Hearing aids and hearing tests are HSA-may be able to access too.

These three categories — dental, vision, and hearing — are often not covered by regular health insurance, or are covered only partially. That's why many people use their HSA for these costs specifically.

Mental health and therapy services

Therapy, counseling, and psychiatric care are HSA-may be able to access. This includes sessions with a therapist, psychiatrist, psychologist, or counselor, whether in person or by video. If your insurance requires you to pay a copay or coinsurance for mental health visits, you can use HSA money for that cost.

Some people have mental health coverage through insurance but choose to pay out of pocket for a therapist not in their insurance network. HSA money can cover that too, as long as the person is a licensed mental health professional.

Medical equipment and supplies you buy yourself

If you need medical equipment — a blood pressure monitor, glucose meter, crutches, a heating pad, or a back brace — HSA money can pay for it. The equipment has to be something a doctor would reasonably prescribe or recommend for a specific medical condition.

Bandages, gauze, and first-aid supplies count. So do items like compression socks (if prescribed for a circulation problem) or a CPAP machine for sleep apnea. Pregnancy tests and ovulation kits are HSA-may be able to access.

The line gets drawn at general wellness. A regular thermometer counts, but a fancy smart scale that just tracks your weight for motivation does not. A humidifier prescribed by a doctor for asthma counts; a humidifier you buy to feel better in winter does not.

What does not count, even if it helps your health

Cosmetic procedures are not HSA-may be able to access, even if they improve how you feel. Botox, teeth whitening, hair removal, and cosmetic surgery do not count. The exception is if the procedure is medically necessary — for example, reconstructive surgery after an injury or illness.

Gym memberships and fitness classes do not count, even if your doctor recommends exercise. Sports equipment, yoga mats, and fitness trackers do not count either. General vitamins and supplements do not count unless prescribed by a doctor for a specific deficiency.

Cosmetic dental work like veneers or whitening does not count. Over-the-counter skincare products do not count. Sunscreen does not count. Weight loss programs and diet plans do not count unless they are part of treatment for a diagnosed medical condition like obesity or diabetes, and even then, only the medically necessary portion counts.

Using your HSA for future costs and retirement

Unlike an FSA, your HSA balance rolls over every year. Money you don't spend stays in the account and earns interest or investment returns, depending on how your HSA is set up. This means you can save your HSA for years, building a reserve for future medical costs.

Some people use their HSA as a retirement savings tool. After age 65, you can withdraw money from your HSA for any reason without penalty — though you'll owe income tax on non-medical withdrawals. But if you use the money for medical expenses, there's no tax, even in retirement.

Keep receipts for any medical expense you pay with HSA money, even if you don't withdraw the money when ready. If you withdraw money years later and the IRS questions it, you'll need proof that the expense was medical and HSA-may be able to access.

Frequently Asked Questions

Can I use my HSA for my spouse's or children's medical expenses?

Yes. You can use your HSA to pay for medical expenses of your spouse and dependents, even if they're not on your health insurance plan. The expense itself has to be HSA-may be able to access — it's the person receiving care that's flexible, not the type of care.

What if I buy something over the counter that needs a prescription — do I have to get the prescription before I buy it?

No. You can buy the item first, then get a prescription or written order from your doctor after. As long as you have the prescription on file before you submit the receipt to your HSA administrator or claim the expense, it counts. Keep the receipt and the prescription together.

Can I use HSA money to pay for someone to help me with medical care at home?

Yes, if the person is providing medical care — like a nurse, physical therapist, or home health aide. You cannot use HSA money to pay for general household help or caregiving that isn't medical in nature, even if it helps you manage a health condition.

Does my HSA cover the cost of travel to get medical treatment?

Travel to receive medical care — gas, airfare, lodging, or meals — is not HSA-may be able to access. The medical treatment itself is, but the cost of getting there is not, even if you're traveling for a procedure your regular doctor can't provide locally.

What happens if I use my HSA money for something that's not HSA-may be able to access?

You'll owe income tax on that amount, plus a 20 percent penalty. The penalty drops to zero after age 65, but you still owe the income tax. Keep records of what you spend HSA money on so you can avoid this mistake.
