HSA money covers medical expenses that your insurance won't pay for, plus some that it will

An HSA (Health Savings Account) is designed to pay for may have access to medical expenses—a specific list set by the IRS. You can use the money for deductibles, copays, and coinsurance on your health insurance. You can also use it for expenses your insurance doesn't cover at all: dental work, vision care, hearing aids, prescription drugs, mental health counseling, and physical therapy. The key is that the expense must be for diagnosis, treatment, or prevention of a medical condition. Cosmetic procedures, gym memberships, and over-the-counter vitamins don't count unless a doctor prescribes them for a specific condition.

The money in your HSA is yours to keep year to year—it doesn't disappear at the end of the year like a Flexible Spending Account (FSA) does. You can let it grow and use it later in life, even after you retire. But if you spend it on something that isn't a may have access to medical expense, you'll owe income tax on that amount plus a 20% penalty (unless you're over 65, in which case you only owe the income tax).

Key Takeaways

  • HSA funds cover insurance deductibles, copays, coinsurance, and out-of-pocket medical costs that insurance doesn't pay for.
  • Dental, vision, hearing aids, prescription drugs, and mental health care are covered HSA expenses even if your insurance doesn't pay for them.
  • Over-the-counter items like pain relievers, cold medicine, and vitamins are covered only if a doctor prescribes them for a diagnosed condition.
  • Spending HSA money on non-may have access to expenses triggers income tax plus a 20% penalty, so the list matters.
  • Your HSA balance rolls over year to year and can be used decades later, making it different from an FSA.

Medical expenses your insurance covers

If your insurance pays for it, your HSA can pay for it too. This includes deductibles (the amount you pay before insurance kicks in), copays (the fixed amount per visit), and coinsurance (your percentage of the cost after insurance pays its share). It also covers the out-of-pocket maximum—the most you'll pay in a year before insurance covers everything at 100%.

You can use your HSA to cover these costs even while you're still meeting your deductible. For example, if your deductible is $1,500 and you have a doctor visit that costs $200, you can pay that $200 from your HSA. The visit still counts toward your deductible, but the HSA pays the bill.

Medical expenses your insurance doesn't cover

Many healthcare costs fall outside what insurance will pay for. Dental work—fillings, crowns, root canals, cleanings—is covered by HSA funds even if you don't have dental insurance or your dental plan won't cover it. Vision care works the same way: eye exams, glasses, contact lenses, and laser eye surgery are all HSA-may be able to access.

Hearing aids and related services are covered. Mental health counseling and therapy sessions are covered. Physical therapy, chiropractic care, and acupuncture are covered if a doctor orders them. Prescription drugs are covered. Insulin, diabetic supplies, and other chronic disease management tools are covered. If a doctor says you need it for a medical condition, the HSA can pay for it.

Some less obvious expenses count too: crutches, wheelchairs, and other medical equipment; home modifications for disability access; and even some travel costs if you're traveling for medical treatment that isn't available where you live.

Over-the-counter items: the prescription rule

Over-the-counter pain relievers, cold medicine, allergy medicine, and antacids are not covered by HSA unless a doctor prescribes them. A prescription doesn't mean a written order from a pharmacy—it means a doctor has written or verbally directed you to take that specific medication for a specific condition. If you buy ibuprofen on your own for a headache, that's not covered. If your doctor tells you to take ibuprofen twice daily for arthritis, that's covered.

The same rule applies to vitamins and supplements. A multivitamin you buy for general health is not covered. A vitamin D supplement prescribed by your doctor for a deficiency is covered. You need documentation showing the doctor recommended it—a note in your medical record or a written prescription.

What doesn't count as a may have access to expense

Cosmetic procedures are not covered unless they're correcting an injury or deformity. Botox for wrinkles is not covered. Reconstructive surgery after an accident is covered. Teeth whitening is not covered. Orthodontics (braces) is not covered in most cases, though some plans do cover it—check your plan documents.

General wellness expenses don't count: gym memberships, fitness classes, diet programs, and weight loss supplements are not covered even if they improve your health. Sunscreen, toothpaste, and other hygiene products are not covered. Maternity clothes, diapers, and baby formula are not covered. Travel for vacation or general wellness is not covered, even if you're traveling to a warmer climate for your health.

Long-term care insurance premiums are not covered. Life insurance is not covered. Health insurance premiums themselves are generally not covered (with narrow exceptions for COBRA, Medicare, and military health insurance).

How to document what you spend

Keep receipts and invoices for everything you pay with your HSA. The IRS doesn't require you to submit them when you withdraw money, but you need to be able to prove the expense was may have access to if you're ever audited. A receipt should show the date, the provider's name, what was provided or purchased, and the amount paid.

If you use an HSA debit card, the transaction record from your bank serves as documentation. If you pay out of pocket and reimburse yourself later, keep the original receipt. If a provider bills your HSA directly, their invoice is your documentation.

Some HSA providers offer apps or portals where you can upload receipts. This isn't required by law, but it makes your record-keeping easier. If you can't find a receipt years later, a statement from the provider showing the service date and cost can work as backup documentation.

Using HSA money for family members

You can use your HSA to pay for may have access to medical expenses of your spouse and dependents, even if they're not on your health insurance plan. If your child has a separate insurance plan or no insurance at all, you can still use your HSA to pay for their dental work, glasses, or doctor visits. The expense has to be may have access to, but it doesn't matter who the patient is as long as you claim them as a dependent on your taxes (or your spouse is the dependent).

You cannot use HSA money to pay for a parent's medical expenses unless you claim them as a dependent on your tax return, which has specific income and support requirements. Check your tax situation before assuming a parent's expenses are covered.
