A health savings account can pay for medical expenses that your insurance doesn't cover, and the money rolls over year to year

Your HSA money can go toward almost any medical, dental, or vision cost that your insurance plan doesn't pay for. That includes deductibles, copays, coinsurance, and treatments your plan excludes entirely. The key rule is straightforward: the expense has to be for diagnosis, treatment, or prevention of a health condition — not general wellness or comfort.

Unlike a flexible spending account (FSA), which forces you to spend the money or lose it each year, HSA money stays in your account indefinitely. You can let it grow, invest it, and use it years later. This makes an HSA useful both as a way to pay for care right now and as a long-term savings tool.

Key Takeaways

  • You can use HSA funds for your deductible, copays, and coinsurance — the out-of-pocket costs your insurance plan requires.
  • Dental work, vision care, hearing aids, and mental health treatment all count as may be able to access expenses, even if your health plan doesn't cover them.
  • Over-the-counter medicines and medical supplies like bandages, crutches, and blood pressure monitors are covered, but only if you have a prescription or doctor's note.
  • You cannot use HSA money for insurance premiums, cosmetic procedures, or general health products like vitamins or gym memberships.
  • Money left unspent in your HSA rolls over to the next year and can be invested to grow over time.

Deductibles, copays, and coinsurance your plan requires

The most straightforward use for HSA money is paying the out-of-pocket costs your insurance plan assigns to you. When you see a doctor and owe a copay, you can use your HSA debit card or reimburse yourself from the account. The same applies to your annual deductible — the amount you have to pay before your insurance starts covering costs — and coinsurance, which is your percentage of the bill after the deductible is met.

These are the expenses that make an HSA most useful for people with high-deductible health plans. If your deductible is $1,500 or $3,000, your HSA lets you set aside pre-tax money specifically for those costs, reducing what you actually pay out of pocket.

Dental and vision care not covered by your plan

Many health insurance plans exclude dental and vision care entirely, or cover them only partially. Your HSA can pay for any dental expense: cleanings, fillings, root canals, crowns, braces, and extractions. Vision expenses include eye exams, glasses, contact lenses, and laser eye surgery. Hearing aids and hearing exams also count.

This is one of the biggest advantages of an HSA for people whose insurance has gaps. If your plan doesn't cover dental work, you can use pre-tax HSA money instead of paying with after-tax dollars. The same applies to vision care or any other service your plan excludes.

Over-the-counter medicines and medical supplies

You can use HSA money for over-the-counter medicines like pain relievers, allergy medications, and cold medicines — but only if you have a prescription or a written note from your doctor saying you need them. Without that documentation, the IRS does not consider them may be able to access expenses. If your doctor prescribes an over-the-counter medicine, keep the prescription with your records.

Medical supplies are broader. Bandages, gauze, crutches, wheelchairs, blood pressure monitors, thermometers, and glucose meters all count. Sunscreen counts as a medical supply only if your doctor prescribes it for a specific skin condition. Toothpaste and toothbrushes do not count, even though they relate to health.

Mental health treatment and therapy

Therapy, counseling, and psychiatric care are all may be able to access HSA expenses. This includes sessions with a therapist, psychiatrist, or counselor, whether or not your insurance covers them. If your plan has a copay for mental health visits, you can use your HSA to pay it. If your plan excludes mental health care entirely, you can use HSA money to pay the full cost of treatment out of pocket.

Inpatient mental health treatment, such as a stay in a psychiatric hospital or residential treatment facility, also qualifies. Keep receipts and invoices from your provider so you can document the expense if the IRS ever asks.

What you cannot use HSA money for

Health insurance premiums themselves are off-limits for HSA money, with one exception: if you are receiving unemployment benefits, you can use your HSA to pay for health insurance premiums while unemployed. Otherwise, premiums — whether for your health plan, dental plan, or vision plan — must come from other money.

Cosmetic procedures do not count, even if they are performed by a doctor. Botox, teeth whitening, and elective plastic surgery are not may be able to access. General wellness products like vitamins, supplements, and gym memberships are not covered unless your doctor prescribes a specific supplement for a diagnosed condition and documents it in writing. Maternity clothes, even though they relate to pregnancy, are not may be able to access.

Using your HSA for expenses years later

Unlike an FSA, which operates on a "use it or lose it" basis, your HSA money does not disappear at the end of the year. You can let it accumulate, and many HSA accounts let you invest the balance in mutual funds or other investments, similar to a retirement account. This means you can use HSA money for medical expenses that occur years in the future.

Some people use their HSA as a long-term savings tool: they pay for current medical expenses out of pocket and let the HSA grow, then withdraw money later in retirement when medical costs are typically higher. Keep receipts for any medical expenses you pay out of pocket, because you can reimburse yourself from your HSA at any point in the future, even decades later, as long as you have documentation that the expense was may be able to access.

Keeping records and avoiding problems

The IRS can audit HSA withdrawals, so keep receipts and invoices for anything you pay for with HSA money. If you withdraw money for something that is not may be able to access and cannot document that it was, you owe income tax on that amount plus a 20 percent penalty. The penalty applies only to non-may be able to access withdrawals, not to the entire account.

If you are unsure whether an expense qualifies, contact your HSA provider — they can often tell you whether similar expenses have been approved in the past. When in doubt, pay for the expense out of pocket and keep the receipt. You can always reimburse yourself from your HSA later if you confirm the expense was may be able to access.
