This template is educational and is not medical, tax, or legal advice. Only a licensed clinician can determine medical necessity, and HSA/FSA eligibility depends on your account and IRS rules. Keep the signed letter with your purchase receipt in case of an audit.
How a Letter of Medical Necessity makes a sauna HSA/FSA eligible
Because saunas are not on the IRS standard list of qualified medical expenses, a sauna only becomes HSA or FSA eligible when a licensed clinician documents that it is medically necessary to treat, mitigate, or prevent a diagnosed condition. That document is the Letter of Medical Necessity. With a valid LMN on file, a qualifying sauna purchase may be paid for with pre-tax HSA or FSA dollars, which reduces the effective cost by an average of about 30 percent. Common conditions clinicians evaluate include chronic pain, arthritis, and similar diagnoses, but eligibility is always decided case by case by your provider. Save the signed letter alongside your receipt so you have documentation if the IRS ever questions the expense. For full eligibility details, see our HSA and FSA page, and browse qualifying cabins in our infrared sauna collection.

Frequently asked questions
Is an infrared sauna HSA or FSA eligible?
It can be, with a Letter of Medical Necessity from a licensed clinician confirming the sauna is medically appropriate for a diagnosed condition. Without an LMN, a sauna is generally not a qualified expense. Your provider and your account rules determine eligibility.
How fast can I get a Letter of Medical Necessity?
It depends on your provider. Some clinicians complete one during a regular visit, and some online services issue an LMN within hours after a clinical intake. Always work with a licensed provider who can assess your situation.
What should the letter include?
A typical LMN names the patient, the diagnosed condition, the recommended product (the sauna), the clinical rationale, the recommended duration, and the provider's name, credentials, and signature. The template above is organized around these elements.
