How to Use Your HSA or FSA for EWOT and Red Light Therapy
Health savings accounts (HSAs) and flexible spending accounts (FSAs) let you pay for qualified medical expenses with pre-tax dollars, which can meaningfully lower the real cost of home wellness equipment. So one of the most common questions we get is simple: is red light therapy HSA eligible, and what about an EWOT system?
The answer is that neither is automatically eligible, but both may be reimbursable when they are used for a specific medical condition and documented with a letter of medical necessity. This guide explains how that works, step by step, and what One Thousand Roads can and cannot do on our end.
Quick Answer
Red light therapy panels and EWOT systems are not automatically HSA or FSA eligible because they can be used for general wellness. They may be reimbursable when a healthcare provider documents that you need them for a specific medical condition in a letter of medical necessity (LMN). You can get an LMN from your own doctor or through a telehealth service such as Crates Health. You pay for your order normally, then submit the receipt and LMN to your plan administrator, who makes the final decision. One Thousand Roads does not process HSA or FSA payments directly.
Is Red Light Therapy HSA Eligible?
Not by default. HSA and FSA funds can be used for medical care, which generally means items used primarily to address a specific disease or condition. Products that are commonly used for general health or cosmetic purposes, like a red light panel used for skin or overall wellness, fall into a gray zone. Plan administrators usually ask for proof that the purchase is medically necessary for you.
That proof is the letter of medical necessity. When a licensed provider documents that red light therapy is part of managing a diagnosed condition, such as chronic joint pain, a red light panel may be reimbursable. Whether it is approved depends on your plan and your documentation.
Some administrators also look at whether a device has FDA clearance for a particular use. Requirements vary by plan, so check before you buy. Our guide to FDA-cleared vs FDA-approved red light therapy explains what those terms mean.
Is EWOT HSA or FSA Eligible?
Exercise with oxygen therapy (EWOT) follows the same logic. An EWOT system, a concentrator, reservoir and mask used during light exercise, is not automatically eligible, but it may be reimbursable with an LMN when a provider documents it is needed for a specific condition, for example as part of a plan to support circulation or exercise tolerance in a chronic illness.
EWOT and red light together
The same applies to an EWOT and red light combination such as the Oxygen Synergy System: each item on the receipt should be covered by the LMN.
What a Letter of Medical Necessity Is
A letter of medical necessity is a short document from a licensed healthcare provider that states your diagnosis, the item or therapy recommended, why it is needed for that condition, and usually how long you will need it. Administrators use it to separate medical purchases from general wellness purchases.
Option 1: your own doctor
If you already work with a physician, naturopathic doctor or other licensed provider who knows your history, ask them to write the LMN. Bring the product name and a short description of how you plan to use it.
Option 2: Crates Health
Crates Health is a telehealth service that helps people get LMNs for HSA and FSA purchases. You complete a health questionnaire, a licensed provider reviews it, and if they determine the item is appropriate for your condition they issue an LMN, often within hours. Crates charges an annual membership fee; check their site for current pricing. You still buy the equipment normally and submit the receipt yourself.
Eligibility rules come from the IRS and your specific plan. One Thousand Roads cannot guarantee reimbursement. Your plan administrator decides, and a tax professional can answer questions about your situation.
Step by Step: Using Your HSA or FSA
- Check your plan. Log in to your HSA or FSA portal or call the administrator and ask how they handle items that need an LMN.
- Get your LMN. From your own provider or a service like Crates Health. Make sure it names the specific item.
- Buy normally. Order from One Thousand Roads with your regular card or financing. We do not process HSA or FSA payments directly.
- Submit for reimbursement. Upload your itemized receipt and LMN to your administrator.
- Keep records. Save the receipt, LMN and approval in case of an audit.
Some people ask whether they can swipe an HSA debit card at checkout. Because these items usually need an LMN, paying normally and claiming reimbursement is the cleaner path and keeps your documentation in order.

HSA vs FSA Rules to Know
| Feature | HSA | FSA |
|---|---|---|
| Who can have one | People on a qualifying high-deductible health plan | Employees whose employer offers one |
| Do funds roll over? | Yes, the account is yours | Often use-it-or-lose-it; some plans allow a grace period or limited carryover |
| Reimburse later? | Generally yes, with records | Usually within the plan year and claim deadline |
| LMN needed for dual-use items | Usually | Usually |
FSA deadlines are the biggest trap. If you are using FSA money, check your plan year end and claim deadline before ordering.
Choosing a system before you request your LMN
Your LMN should name the item you will buy, so decide first. For EWOT, both systems use the same approach and oxygen purity; the difference is refill time and upfront cost.

If Your Claim Is Not Approved
Administrators sometimes deny a first submission because the LMN is missing details. Ask what was missing, have the provider add the diagnosis and specific item, and resubmit. If HSA or FSA funds are not an option, our financing options can spread the cost over time. It also helps to compare against the ongoing cost of clinic sessions; see what a hyperbaric chamber actually costs and our mild hyperbaric chamber vs EWOT comparison.
EWOT and red light therapy are supportive wellness practices and are not intended to diagnose, treat, cure, or prevent disease. Individuals experiencing symptoms of a health condition should consult their healthcare provider before beginning any new therapy.
