If you've been squinting at your HSA balance and wondering whether it covers anything beyond doctor's office copays, the answer is more generous than most people realize. Health Savings Accounts cover a surprisingly wide range of expenses — including dental care, vision care, and mental health treatment — but the details matter. Here's what you need to know to use your HSA confidently and correctly.
The IRS sets the rules for what counts as a qualified medical expense under an HSA. The governing standard comes from IRS Publication 502, which defines eligible expenses broadly as costs paid for the "diagnosis, cure, mitigation, treatment, or prevention of disease" — or for treatments affecting any structure or function of the body.
That definition is intentionally wide. It covers far more than hospital stays and prescriptions. Dental and vision care have always been included in that framework, and mental health care has received growing recognition as well. The key is whether the specific expense fits that IRS definition — and not all expenses within these categories do.
Most dental care qualifies as an HSA-eligible expense, which surprises people who assume their HSA only applies to medical insurance claims.
Covered dental expenses typically include:
What generally does NOT qualify:
The line the IRS draws is between medically necessary or preventive care and cosmetic enhancement. A crown to repair a damaged tooth qualifies. Whitening because you want a brighter smile does not. If there's a legitimate medical reason documented by your dentist for something that might otherwise seem cosmetic, that documentation matters and may affect eligibility.
Vision expenses follow similar logic — many qualify, some don't.
Covered vision expenses typically include:
What generally does NOT qualify:
One area that trips people up: designer frames. If you need prescription glasses, the frames are part of that eligible expense — but if you're buying frames that are significantly more expensive than a basic pair, there's no HSA rule that limits your choice. You can pay for premium frames with HSA funds as long as the glasses themselves serve a corrective medical purpose.
Mental health has historically been an underappreciated corner of HSA eligibility, but it is clearly covered under the IRS framework.
Covered mental health expenses typically include:
Areas with more nuance:
The consistent standard: is this treating or diagnosing a medical or mental health condition? If yes, it almost certainly qualifies. If it's general wellness without a clinical basis, it likely doesn't.
If you have a Flexible Spending Account (FSA) instead of an HSA, the eligible expense categories are largely the same — dental, vision, and mental health all qualify under similar IRS rules. The structural differences between HSAs and FSAs (who can open them, contribution limits, rollover rules) are significant, but for the purpose of what you can spend the money on, the eligible expense lists are closely aligned.
| Expense Category | HSA Eligible | FSA Eligible |
|---|---|---|
| Dental cleanings and treatment | ✅ Yes | ✅ Yes |
| Teeth whitening | ❌ No | ❌ No |
| Prescription glasses/contacts | ✅ Yes | ✅ Yes |
| LASIK surgery | ✅ Yes | ✅ Yes |
| Licensed therapy sessions | ✅ Yes | ✅ Yes |
| Life coaching | ❌ No | ❌ No |
| Psychiatric medications | ✅ Yes | ✅ Yes |
Keep your receipts. The IRS can ask you to document that HSA withdrawals were used for qualified expenses. A receipt showing what the expense was — and ideally a provider's documentation — protects you if you're ever audited.
Ask before you pay. If you're unsure whether a specific expense qualifies, your HSA administrator can often tell you. IRS Publication 502 is also publicly available and surprisingly readable for a tax document.
Non-qualified expenses carry real costs. If you use HSA funds for something that doesn't qualify, that withdrawal is subject to income tax plus a penalty for those under 65. The penalty goes away at 65, but the income tax remains. This is not a gray area to gamble on.
Your HSA administrator has final say on processing — but the IRS defines eligibility. If a provider submits a claim incorrectly or your administrator flags something, it's worth understanding whether the issue is administrative or a genuine eligibility question.
A few variables determine whether your particular situation fits the qualified expense definition:
Understanding these factors helps you evaluate your own situation — and know when it's worth asking a tax professional or your benefits administrator for guidance on a specific expense.
