Qualifying Medical Conditions & How to Get Approved To Buy a Sauna With HSA or FSA Funds

Saunas aren't automatically covered by your Health Savings Account (HSA) or Flexible Spending Account (FSA). However, with a Letter of Medical Necessity from a licensed healthcare provider, a sauna can become a qualified medical expense—allowing you to use pre-tax dollars to fund your purchase and potentially save 20-40% on your investment.

This guide explains the medical conditions that commonly qualify for HSA/FSA sauna coverage, how to obtain the required documentation, and what you need to know to maximize your tax-advantaged health benefits.

What Makes a Sauna HSA or FSA Eligible?

According to IRS guidelines, HSA and FSA funds can only be used for expenses that are primarily for the prevention or alleviation of a physical or mental defect or illness. General wellness purchases don't qualify—but when a sauna is prescribed as a medical treatment, it becomes an eligible expense.

The key document required is a Letter of Medical Necessity (LMN). This is a written statement from your doctor or licensed healthcare provider that explains why a sauna is medically necessary for your specific health condition. Without this letter, you cannot use HSA or FSA funds for a sauna purchase.

How to Get a Letter of Medical Necessity (The Traditional Way)

While using TrueMed at checkout is the fastest and easiest method for Haven Of Heat customers, you can also obtain a Letter of Medical Necessity directly from your own healthcare provider. This may be preferred if you have an established relationship with a doctor who is familiar with your medical history.

Step 3: Request the Letter

Ask your provider to write a Letter of Medical Necessity that includes the following elements:

• Your diagnosis – The specific medical condition being treated

• Treatment rationale – How sauna therapy will help manage or treat your condition
• Duration of need – Whether the treatment is needed temporarily or indefinitely
• Provider information – Name, credentials, license number, and contact information

How to Submit for HSA/FSA Reimbursement

The easiest method is to use TrueMed directly at checkout—simply select "TrueMed - Pay with HSA/FSA," complete the health assessment, and pay with your HSA/FSA card. If approved, you're done.

If you obtained your LMN from your own doctor or need to submit for reimbursement after the fact, follow these steps:

For HSA Accounts

1. Keep your documentation – Store your LMN and purchase receipt together
2. Pay from your HSA – If your HSA has a debit card, you may be able to use it directly at checkout
3. Submit for reimbursement – If you pay out of pocket, submit your receipt and LMN to your HSA administrator
4. Retain records – Keep all documentation for tax purposes (the IRS recommends keeping records for at least three years)

For FSA Accounts

1. Check your plan – Verify that durable medical equipment is covered under your specific FSA plan
2. Submit a claim – Provide your FSA administrator with the LMN, itemized receipt, and claim form
3. Track deadlines – Remember that FSA funds typically must be used within the plan year (some plans offer grace periods or carryover)

Choosing the Right Sauna for Your Medical Needs

Different medical conditions may benefit from different types of saunas. Here's a quick overview to help you discuss options with your healthcare provider:

Traditional Saunas

Traditional saunas heat the air to high temperatures (150-195°F) and can incorporate steam by pouring water over heated rocks. They may be particularly beneficial for:

• Respiratory conditions (with steam)
• Cardiovascular health
• Overall detoxification
• Those who prefer intense heat experiences

Infrared Saunas

Infrared saunas use infrared light to heat the body directly at lower air temperatures (120-140°F). They may be preferred for:

• Chronic pain conditions (deeper tissue penetration)
• Those who cannot tolerate high heat
• Skin conditions
• Extended session times
• Energy efficiency

Full Spectrum Infrared Saunas

Full spectrum infrared saunas emit near, mid, and far infrared wavelengths, providing the most comprehensive infrared therapy. They're ideal for:

• Maximum therapeutic benefit
• Multiple health conditions
• Combined skin and deep tissue treatment

Hybrid Saunas

Hybrid saunas combine traditional heating with infrared technology, allowing you to switch between modes or use both simultaneously. They're excellent for:

• Maximum versatility
• Users with multiple conditions
• Households with different preferences

Red Light Therapy Saunas

Red light therapy saunas add photobiomodulation benefits to your sauna sessions. The combination may be particularly beneficial for:

• Skin health and anti-aging
• Wound healing
• Joint and muscle recovery
• Inflammation reduction

Complementary HSA/FSA Eligible Wellness Products

If you're building a comprehensive home wellness setup with HSA/FSA funds, consider these additional products that may also qualify with appropriate medical documentation:

Cold Plunge Therapy

Cold plunge tubs can be prescribed for inflammation reduction, muscle recovery, and mental health conditions. Many practitioners recommend contrast therapy (alternating hot and cold) for maximum therapeutic benefit.

Red Light Therapy Devices

Red light therapy panels and devices may be prescribed for pain management, wound healing, skin conditions, and inflammation. These can be used independently or combined with sauna therapy.

PEMF Mats

PEMF (Pulsed Electromagnetic Field) mats may be prescribed for pain management, bone healing, and inflammation reduction.

Frequently Asked Questions

Can I use my HSA/FSA to buy a sauna without a Letter of Medical Necessity?

No. Without proper medical documentation, a sauna is considered a general wellness purchase and does not qualify for HSA/FSA funds. The IRS requires that expenses be primarily for medical care to be eligible.

Do all doctors write Letters of Medical Necessity?

Not all doctors are familiar with sauna therapy or willing to write LMNs for sauna purchases. If your primary care physician declines, consider consulting with a naturopathic doctor, integrative medicine specialist, or provider familiar with heat therapy treatments. Alternatively, use TrueMed at checkout—their network of licensed medical practitioners can evaluate your eligibility and issue an LMN within 24-48 hours.

What is TrueMed and how does it work?

TrueMed is our partner that makes HSA/FSA purchases seamless. When you select "TrueMed - Pay with HSA/FSA" at checkout, you'll complete a brief health assessment. TrueMed's licensed medical practitioners review your information and, if you qualify, issue a Letter of Medical Necessity. This eliminates the need to schedule a separate doctor's appointment. The entire process takes just a few minutes at checkout, and you'll receive your LMN within 24-48 hours.

What if my HSA/FSA administrator denies my claim?

If your claim is denied, you can appeal the decision. Make sure your LMN clearly explains the medical necessity and includes all required information. You may also need to provide additional documentation or research supporting sauna therapy for your condition.

Can I get reimbursed for a sauna I already purchased?

In some cases, yes. If you can obtain a Letter of Medical Necessity that was dated before or at the time of purchase, you may be able to submit for retroactive reimbursement. Check with your HSA/FSA administrator for their specific policies.

Is installation or delivery covered by HSA/FSA?

Typically, only the cost of the sauna itself is covered. Installation, delivery, and accessories are generally not considered qualified medical expenses unless specifically included in your LMN as medically necessary.

What's the difference between HSA and FSA for sauna purchases?

Both can be used for qualified medical expenses including saunas with proper documentation. Key differences:

• HSA funds roll over indefinitely and are yours to keep even if you change jobs
• FSA funds typically expire at the end of the plan year (with some exceptions for grace periods or limited carryover)
• HSA requires a high-deductible health plan to contribute
• FSA contribution limits are lower than HSA limits

How much can I save using HSA/FSA funds?

Since HSA and FSA contributions are made with pre-tax dollars, you effectively save your marginal tax rate on the purchase. For most people, this means savings of 20-40% depending on your federal, state, and local tax rates.

Do I need a new LMN every year?

For ongoing conditions, a single LMN is typically sufficient for the sauna purchase. However, you should keep the documentation indefinitely in case of an audit. If your condition changes or you're purchasing additional equipment, you may need updated documentation.
