Your HSA covers medical expenses that your insurance doesn't, plus some things insurance won't touch at all

An HSA works like a tax-advantaged savings account for healthcare costs. Money you put in reduces your taxable income, grows tax-free, and comes out tax-free when you spend it on may have access to medical expenses. The IRS maintains a specific list of what counts. Some items are obvious—copays, deductibles, prescription drugs. Others surprise people: dental work, vision care, therapy, and certain over-the-counter items all may have access to. The catch is that non-medical purchases trigger taxes plus a 20% penalty if you're under 65.

What you can spend depends partly on what your health insurance plan covers. If your plan pays for something, your HSA can cover your share of the cost—the copay, coinsurance, or deductible. If your plan doesn't cover something at all, your HSA can still pay for it, as long as the IRS considers it a medical expense. This matters because it means your HSA can fill gaps your insurance leaves open.

Key Takeaways

  • HSA money covers copays, coinsurance, deductibles, and out-of-pocket costs your insurance requires you to pay.
  • Prescription drugs, dental care, vision care, mental health treatment, and physical therapy all may have access to, whether your insurance covers them or not.
  • Over-the-counter items like pain relievers, allergy medicine, and first-aid supplies may have access to only if you have a doctor's prescription or letter stating medical necessity.
  • Non-medical purchases—cosmetic procedures, gym memberships, vitamins without a prescription—trigger income tax plus a 20% penalty before age 65.
  • After age 65, you can withdraw HSA money for any reason without penalty, though non-medical withdrawals are still taxed as income.

Prescription and over-the-counter medications

Prescription drugs always may have access to. Fill them at any pharmacy and pay with your HSA debit card or submit a receipt for reimbursement. The medication itself, not the pharmacy markup, is what counts—so the full cost qualifies.

Over-the-counter medications are trickier. Aspirin, ibuprofen, allergy medicine, cold medicine, antacids, and similar items may have access to only if you have a prescription or a written statement from your doctor saying you need it for a specific medical condition. A doctor's note saying "Patient has seasonal allergies and should use loratadine" is enough. A receipt for Claritin you bought on your own is not. This rule changed in 2020, and many people still don't know about it. If you want to use HSA funds for OTC drugs, ask your doctor for a prescription or a brief letter of medical necessity.

Dental and vision care

Dental work qualifies in full: cleanings, fillings, root canals, crowns, orthodontia, and extractions. You do not need your medical insurance to cover it. If you have separate dental insurance, your HSA covers your copays and deductibles to that plan, plus any costs your dental plan doesn't cover. Cosmetic dentistry—teeth whitening purely for appearance—does not may have access to unless a doctor documents that it is medically necessary.

Vision care works the same way. Eye exams, glasses, contact lenses, and corrective surgery (LASIK, PRK) all may have access to. If you have vision insurance, your HSA covers your share of the cost. If you don't, your HSA covers the full cost. Sunglasses do not may have access to, even if they have a prescription, because they are considered cosmetic.

Mental health and therapy

Therapy, counseling, and psychiatric care all may have access to. This includes sessions with a licensed therapist, psychologist, psychiatrist, or counselor. Your HSA covers the full cost of the session or your insurance copay, whichever applies. Medications prescribed by a psychiatrist or other doctor for mental health conditions may have access to as prescription drugs.

Some wellness programs—meditation apps, stress-reduction classes—do not may have access to on their own because they are not treatment for a diagnosed condition. However, if a doctor prescribes or refers you to a specific program as treatment for anxiety, depression, or another diagnosed condition, you may be able to use HSA funds. Ask the program provider whether they accept HSA payments and whether they require a doctor's referral.

Medical equipment and supplies

Bandages, crutches, wheelchairs, hearing aids, blood pressure monitors, glucose meters, and similar items may have access to. So do the supplies that go with them: test strips, lancets, batteries, and replacement parts. You do not need a prescription for most of these, though some HSA administrators ask for a doctor's letter confirming medical necessity.

Items that blur the line between medical and personal—like a mattress for someone with back pain, or a humidifier for someone with asthma—require documentation. A doctor's letter stating that the item is medically necessary for a specific condition usually satisfies the HSA administrator. Without it, the purchase may be denied or flagged for audit.

Preventive care and screenings

Preventive services covered by your insurance at no cost to you—annual physicals, cancer screenings, vaccinations—do not use HSA funds because you do not pay anything out of pocket. However, if you have a high-deductible plan and have not yet met your deductible, you may owe a cost for these services, and your HSA can cover that cost.

Preventive services not covered by insurance—such as certain wellness screenings or genetic testing that your plan does not cover—can be paid with HSA funds if a doctor orders them for a medical reason. A screening you choose for peace of mind, without a doctor's recommendation, typically does not may have access to.

What does not may have access to

Cosmetic procedures—facelifts, Botox, hair removal—do not may have access to unless medically necessary. Gym memberships and fitness classes do not may have access to, even if prescribed for weight loss or heart health, because they are general wellness rather than treatment. Vitamins and supplements do not may have access to unless prescribed by a doctor for a specific deficiency or condition. Toothpaste, mouthwash, and shampoo do not may have access to because they are personal hygiene items, not medical treatment.

Health insurance premiums themselves do not may have access to for HSA withdrawal, with narrow exceptions: you can use HSA funds to pay premiums while you are receiving unemployment benefits, or to pay Medicare premiums (Part A, B, D, and supplemental) after age 65. You cannot use HSA funds to pay premiums for other types of insurance, such as life insurance or disability insurance.

How to pay and keep records

Most HSA accounts come with a debit card. Swipe it at the pharmacy, doctor's office, or medical supplier and the cost comes straight from your HSA balance. Some providers let you pay out of pocket and submit a receipt for reimbursement later. Keep receipts and explanations of benefits (EOBs) from your insurance. If the IRS audits your HSA, you will need to show that the money went to may have access to expenses.

Some expenses—especially those that blur the line between medical and personal—may be questioned by your HSA administrator. A doctor's letter or prescription makes the case stronger. If a purchase is denied, you can appeal or ask the provider to reconsider with additional documentation. If you withdraw money for a non-may have access to expense by mistake, you have until tax time to put it back without penalty, though you will owe taxes on the earnings.

Frequently Asked Questions

Can I use my HSA to pay my insurance deductible?

Yes. Your HSA covers any out-of-pocket cost your insurance requires you to pay, including deductibles, copays, and coinsurance. This is one of the main reasons people fund HSAs alongside high-deductible plans.

Do I need a prescription for bandages or first-aid supplies?

No. Basic supplies like bandages, gauze, and antiseptic cream may have access to without a prescription. However, some HSA administrators may ask for a doctor's letter if the quantity or type seems unusual, or if you are buying them regularly in large amounts.

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

Yes, as long as they are covered under your health insurance plan or you claim them as dependents on your tax return. You can pay their copays, deductibles, prescriptions, and other may have access to expenses directly from your HSA.

What happens if I use my HSA for something that doesn't may have access to?

You owe income tax on the amount withdrawn, plus a 20% penalty if you are under 65. After 65, the penalty goes away, but you still owe income tax on non-medical withdrawals. Keep receipts so you can prove what the money was spent on if questioned.

Can I use my HSA for a gym membership if my doctor recommends it?

Generally no. Gym memberships and fitness classes do not may have access to even with a doctor's recommendation, because they are general wellness rather than treatment for a diagnosed condition. However, physical therapy prescribed by a doctor for an injury or condition does may have access to.
