HSA Qualified Medical Expenses: What Counts

Health Savings Account (HSA) funds can only be withdrawn tax-free when applied to expenses the IRS classifies as qualified medical expenses. Understanding this classification is essential because an incorrect withdrawal triggers both income tax and a 20 percent penalty on the distributed amount (IRS Publication 502). This page defines the scope of qualified expenses, explains the mechanism governing eligibility, walks through common scenarios, and clarifies the decision boundaries where coverage is disputed or conditional.

Definition and Scope

The IRS defines a qualified medical expense as any cost that diagnoses, cures, mitigates, treats, or prevents disease, or that affects any structure or function of the body — provided it is not reimbursed by insurance or any other source (IRS Publication 502). This definition governs HSAs under 26 U.S.C. § 223, which cross-references § 213(d) as the controlling standard for expense eligibility.

The scope covers expenses for the HSA account holder, the holder's spouse, and any tax dependent at the time the expense was incurred — even if the dependent is no longer claimed on a return at the time of withdrawal. Critically, the dependent does not need to be enrolled in the same HDHP that makes the account holder HSA-eligible. A broader overview of how the HSA framework integrates with plan coverage is available on the HDHP Authority home page.

The Consolidated Appropriations Act of 2023 made permanent the pre-pandemic telehealth safe harbor allowing HDHPs to cover telehealth services before the deductible without disqualifying HSA eligibility, but the definition of qualified expenses itself has remained anchored to IRS Publication 502 and its annual updates.

How It Works

When an HSA holder pays for a qualified medical expense, the distribution avoids federal income tax entirely. The sequence of eligibility determination operates as follows:

1. Expense incurred after account establishment. The expense must arise on or after the date the HSA was opened. Retroactive reimbursement of expenses predating the account is not permitted.
2. Not already reimbursed. A cost paid by employer insurance, a Flexible Spending Account (FSA), or any third party cannot be reimbursed again from an HSA. Double-dipping triggers the expense to become non-qualified.
3. Substantiation retained by the account holder. The HSA trustee does not verify individual expenses at the point of withdrawal. The account holder bears documentation responsibility — receipts, Explanation of Benefits (EOB) statements, and provider invoices — in the event of an IRS audit.
4. No age restriction for medical withdrawals. Unlike retirement-style distributions (which become penalty-free at age 65 regardless of purpose), tax-free treatment applies at any age but only for qualified expenses.

A mismatch in any of these conditions converts the distribution to a taxable event subject to the 20 percent additional tax for account holders under age 65 (IRS Publication 969).

Common Scenarios

Clearly Qualified Expenses

• Physician and specialist office visits (the patient's out-of-pocket share)
• Prescription drugs dispensed by a licensed pharmacist
• Dental treatment including fillings, extractions, and orthodontia
• Vision care including eyeglasses, contact lenses, and corrective surgery such as LASIK
• Mental health and substance use disorder treatment from licensed providers
• Insulin — qualified without a prescription requirement since the CARES Act (P.L. 116-136, §3702)
• Over-the-counter medications — reinstated as qualified without a prescription requirement under the same CARES Act provision effective for expenses incurred after December 31, 2019
• Long-term care insurance premiums up to age-based IRS limits (for 2024, the limit for individuals aged 61–70 is $4,710 per IRS Revenue Procedure 2023-34)
• Feminine hygiene products — qualified since the CARES Act

Conditionally Qualified Expenses

• Health insurance premiums — generally not qualified, with three exceptions: COBRA continuation coverage premiums, premiums paid while receiving federal or state unemployment compensation, and Medicare Part A, B, C, or D premiums for account holders age 65 or older
• Cosmetic surgery — not qualified unless correcting a deformity arising from a congenital abnormality, personal injury, or disfiguring disease
• Weight-loss programs — qualified only when a physician prescribes treatment for a specific diagnosed disease (e.g., hypertension, obesity classified as a disease)

Not Qualified

• Gym memberships and general fitness expenses without a specific disease diagnosis
• Teeth whitening and other cosmetic dental procedures
• Nutritional supplements taken for general health (as opposed to treating a diagnosed deficiency)
• Funeral and burial expenses
• Maternity clothing

Decision Boundaries

The sharpest decision boundary separates general health maintenance from medical treatment of a specific condition. The IRS applies a but-for test: would the expense have been incurred but for the medical condition? A standing desk purchased for general ergonomic preference fails this test. A prescribed orthopedic chair following spinal surgery stands a stronger (though not guaranteed) evidentiary case.

HSA vs. FSA Treatment

Both HSAs and FSAs use § 213(d) as the definitional foundation, meaning the qualified expense list is structurally identical. The practical differences are administrative: FSA funds are subject to a use-it-or-lose-it rule (with limited carryover), while HSA balances roll over indefinitely. A detailed comparison of these account types appears at HSA vs. FSA: Key Differences.

Timing and the Reimburse-Later Strategy

IRS rules do not require an account holder to reimburse a qualified expense in the same tax year it was incurred. An account holder may pay out-of-pocket in Year 1, allow HSA funds to grow invested, and reimburse the documented expense in Year 10. The sole requirement is that the HSA must have been open at the time the expense was incurred. This strategy, sometimes called the HSA reimbursement ledger approach, has no statutory time limit but requires meticulous recordkeeping.

Dependents and Divorce

If a child is claimed as a tax dependent by one parent but covered by the other parent's health insurance, the parent who claims the dependency can use HSA funds for the child's qualified expenses — even if that parent does not contribute to insurance covering the child. The dependency test, not the insurance enrollment, controls HSA reimbursement eligibility.

The IRS rules governing HDHPs and HSAs provide statutory context for how these reimbursement rules interact with HDHP plan design requirements.
