Yes, an HSA does cover orthotics. Both custom-molded devices and over-the-counter insoles qualify for tax-free reimbursement from a Health Savings Account, as long as the orthotic treats a medical condition rather than simply providing everyday comfort. Depending on the product and your HSA administrator, you may also need a letter of medical necessity from your provider.
The rule comes from the tax code itself. The IRS defines qualified medical expenses as costs for “the diagnosis, cure, mitigation, treatment, or prevention of disease,” and Publication 502 specifically lists orthopedic shoes and inserts among deductible medical expenses.1IRS. Publication 502, Medical and Dental Expenses Anything eligible under Publication 502 is also eligible for tax-free HSA distribution.2IRS. Publication 969, Health Savings Accounts and Other Tax-Favored Health Plans Insoles bought purely for general wellness fail the test because the IRS excludes expenses “merely beneficial to general health.”
Which Orthotics Are HSA-Eligible
Custom-Molded Orthotics
Custom orthotics designed from a computerized foot analysis or physical mold are eligible. These are typically prescribed by a podiatrist or orthopedic specialist for conditions such as plantar fasciitis, flat feet, high arches, or diabetic foot complications.3HSA Store. Orthotics HSA Eligibility Expect to pay $300 to $800 for the device, plus another $100 to $300 in evaluation and fitting fees. A 2026 survey of 59 clinics found an average all-in cost of $435, though podiatrist-provided orthotics averaged $564 while those from physical therapists averaged $287.4Stride Soles.

Over-the-Counter Insoles
Prefabricated, nonprescription insoles are generally eligible when they are medical-grade or designed to treat a specific condition like heel pain or overpronation.5PowerStep. HSA FSA Eligible Orthotics Basic OTC insoles typically run $20 to $80, with budget options under $15.6GoodRx. Custom Orthotics Cost Arch supports and inserts used for orthopedic purposes are fully reimbursable.7FSA Store. Orthopedic Shoes Eligibility
Orthopedic Shoes
Orthopedic shoes are eligible, but only for the amount by which the specialized shoe exceeds the cost of a comparable non-specialized shoe. A letter of medical necessity is required.7FSA Store. Orthopedic Shoes Eligibility If a pair of orthopedic shoes costs $250 and a comparable regular pair costs $80, only $170 is HSA-eligible.
Braces and Supports
Ankle braces, knee sleeves, wrist supports, back braces, and compression garments are also HSA-eligible.8HSA Store. Ankle Brace HSA Eligibility Some may require a prescription or letter of medical necessity depending on the product and the administrator.9Lively. Ankle Brace Eligibility
When You Need a Letter of Medical Necessity
Whether you need documentation depends on the product and your HSA administrator. FSAFEDS, the federal government’s program, lists orthotic inserts as eligible with just a detailed receipt, while orthopedic shoes require a letter of medical necessity.10FSAFEDS. HCFSA Eligible Expenses Custom orthotics and prescription footwear almost always require one.5PowerStep. HSA FSA Eligible Orthotics When in doubt, get the letter before you buy.
The letter must come from a licensed provider actively managing your care. For foot orthotics, that is usually a podiatrist, though certified pedorthists and prosthetic/orthotic professionals also qualify.11Upstep. Get Reimbursed for Orthotics From HSA A usable letter includes:
- The patient’s identifying information
- The provider’s credentials and contact details
- The specific medical diagnosis
- The recommended treatment or device
- A clinical explanation of why the orthotic is necessary
- The provider’s signature and date12MetLife. Letter of Medical Necessity
Vague language such as “this will improve the patient’s health” is a common reason for denials. The letter must connect the recommendation directly to a documented diagnosis.
How to Pay and Get Reimbursed
You have two options: pay with your HSA debit card at the point of sale, or pay out of pocket and reimburse yourself later.
Some retailers accept HSA debit cards directly. Whether the card works at checkout depends on whether the merchant uses an Inventory Information Approval System (IIAS), which cross-references products against a list of IRS-eligible items at the register. Therapeutic insoles, orthotic inserts, and arch supports appear on that eligible product list.13SIGIS. Eligible Product List Criteria At merchants without this system, or for products flagged as dual-purpose, the card may be declined. Some retailers, such as Superfeet, do not accept HSA debit cards at all and require customers to pay with a regular card and then seek reimbursement.14Superfeet. HSA FSA Eligible Insoles
To reimburse yourself, log in to your administrator’s portal, go to the reimbursement section, enter the expense details, and submit. HealthEquity notes that documentation is not required at the time of claim submission, though records are essential in case of an audit. The IRS expects you to be able to produce records showing the date of purchase, a description of the item, the merchant or provider name, and the amount paid.15HealthEquity. Claim Submission and Documentation
If a reimbursement is denied, start with the denial notice, which will identify the specific reason. Missing documentation is a frequent cause, and the fix is often as simple as submitting the letter of medical necessity you didn’t originally include or providing a more detailed receipt.16HSA for America. How to Appeal a Health Insurance Claim Denial
Recordkeeping and the Penalty for Ineligible Purchases
HSA administrators do not track individual purchases for eligibility. You are solely responsible for verifying that each purchase qualifies and keeping the records to prove it. Because an IRS audit can look back seven years, keeping receipts, letters of medical necessity, and proof of payment for at least that long is recommended.17HR Morning. HSA Requirements, Receipts, and Recordkeeping
If the IRS determines that a purchase did not qualify — for example, insoles bought purely for comfort rather than to treat a diagnosed condition — the distribution is treated as non-qualified income. You owe regular income tax on the amount plus a 20% penalty. The 20% penalty is waived if you are 65 or older, disabled, or deceased, though income tax still applies.2IRS. Publication 969, Health Savings Accounts and Other Tax-Favored Health Plans
How Much You Save
HSA contributions are tax-deductible or made pretax through payroll, earnings grow tax-free, and withdrawals for qualified medical expenses are tax-free. The effective savings on an orthotic purchase equals your marginal tax rate.2IRS. Publication 969, Health Savings Accounts and Other Tax-Favored Health Plans Someone in the 24% federal bracket who spends $500 on custom orthotics saves $120 in federal income taxes by paying with HSA funds. Residents of 48 states also save on state income taxes; California and New Jersey do not recognize the state-level HSA deduction.18HSA for America. How Much Can an HSA Save in Taxes
For 2026, the HSA contribution limit is $4,400 for individual coverage and $8,750 for family coverage, with an additional $1,000 catch-up contribution for those 55 and older. To contribute, you must be enrolled in a high-deductible health plan with a minimum deductible of $1,700 (individual) or $3,400 (family) and a maximum out-of-pocket limit of $8,500 (individual) or $17,000 (family).2IRS. Publication 969, Health Savings Accounts and Other Tax-Favored Health Plans
HSA vs. FSA for Orthotics
Flexible Spending Accounts cover orthotics under the same IRS eligibility rules, but the accounts behave differently. FSA funds are generally use-it-or-lose-it; employers may allow a carryover of up to $660 (2025 to 2026) or $680 (2026 to 2027), or a 2.5-month grace period, but not both.19Fidelity. HSA vs FSA HSA funds roll over indefinitely, and the account belongs to you if you change jobs.20MetLife. What’s the Difference Between an FSA and an HSA
One FSA advantage matters for orthotic timing: the full annual election is available on the first day of the plan year. If you need custom orthotics in January, an FSA lets you spend the full annual balance immediately, while an HSA only lets you spend what has actually been deposited.19Fidelity. HSA vs FSA For 2026, the FSA contribution maximum is $3,400.20MetLife. What’s the Difference Between an FSA and an HSA You generally cannot contribute to both a standard healthcare FSA and an HSA in the same year, though a limited-purpose FSA covering only dental and vision can be paired with an HSA.
