Burst guide cover, for shoppers: the headline "Red light therapy needs a letter" over the line "Skin and pain uses can qualify. Anti-aging does not." with three tags: $35 flat, Refunded if declined, Masks included.

Short answer

It depends on what the device is treating. Red light therapy bought for anti-aging, tanning or general glow is a cosmetic purchase and plans deny it. Used for a documented medical reason, such as supporting skin healing after surgery, treating acne or eczema, or managing joint and muscle pain, it can qualify for FSA and HSA reimbursement.

What makes the difference is a licensed clinician putting your condition and the device in a letter of medical necessity. That covers panels, handheld units and LED face masks alike. A Burst letter is $35, refunded if the clinician declines or your plan denies the claim, and Burst files the claim so your plan pays you out of your account. Request a letter for a red light device.

Research has demonstrated the many benefits of red light therapy, from supporting skin elasticity and muscle recovery to promoting wound healing and reducing inflammation. While it was once limited to expensive in-office treatments, at-home devices have made this noninvasive therapy much more accessible.

Some healthcare providers prescribe the use of a red light device (also called photobiomodulation therapy). In other instances, it's considered a cosmetic therapy or something that falls into the wellness category. This leaves many people wondering, Is red light therapy FSA-eligible or HSA-eligible?

Some red light therapy devices may qualify for FSA or HSA pre-tax spending, often with a letter of medical necessity (LMN). Here's what to know about the types of devices that might qualify, how to get an LMN, and where to buy an eligible device.

FSA and HSA eligibility basics

FSA (flexible spending account) and HSA (health savings account) plans allow you to set aside pre-tax earnings and use the funds to pay for eligible medical expenses.

The IRS (Internal Revenue Service) sets the criteria for what counts as a medical expense. According to Publication 502, "Medical care expenses must be primarily to alleviate or prevent a physical or mental disability or illness." The IRS adds that medical expenses "don't include expenses that are merely beneficial to general health."

Some at-home therapy devices do qualify, but their primary purpose needs to be to treat or manage a specific diagnosed medical condition.

Is red light therapy HSA-eligible or FSA-eligible?

It depends on intended use. A red light therapy device used explicitly for pain relief, acne treatment, or another medical purpose is more likely to be eligible. The same goes for in-office red light therapy treatment administered by a licensed clinician. In either case, you'll probably need an LMN to confirm eligibility.

Red light therapy devices meant for cosmetic use usually aren't eligible.

HSA vs. FSA for red light therapy

The same eligibility rules for medical expenses apply for both HSA and FSA plans. These account types only differ in terms of who owns them, when the funds expire, and annual contribution limits.

Is a red light therapy mask FSA-eligible?

Red light therapy masks are often marketed for anti-aging purposes or other cosmetic uses. But those used for dermatological purposes, such as supporting skin healing after surgery, treating acne, or managing eczema, may be eligible once a licensed clinician confirms it's a medical necessity with an LMN.

When you need a letter of medical necessity

A letter of medical necessity is a formal document written up by a licensed healthcare provider. It explains why a specific product or therapy is needed to treat or manage a diagnosed condition rather than for general wellness or cosmetic purposes.

The practitioner has to sign below a line that says, "I certify that this service or product is medically necessary to treat the specific medical condition described above and is not in any way for general health or for cosmetic purposes."

An LMN is often required to confirm FSA and HSA eligibility for dual-purpose devices. For instance, a red light mask that treats acne (a medical use) and reduces the appearance of fine lines (cosmetic).

The Infra Pod is a red light panel that can promote healing and recovery. This device is eligible with an approved LMN from a medical provider.

Burst's handy LMN guide can help you figure out what products need a letter of medical necessity and how to get one, step by step. The easiest way is through Burst. We handle the paperwork and email the letter in about 12 to 24 hours if a clinician approves your case.

How to pay for red light therapy with FSA or HSA

With an FSA or HSA debit card, you can buy a red light therapy device from an eligible retailer or pay for an in-office treatment at a clinic.

If you weren't issued a card or the merchant doesn't accept this form of payment, you can file a reimbursement claim. When you go the reimbursement route, you'll need to submit an itemized receipt and likely an LMN.

Be sure to save all receipts, along with the LMN and any other provider documentation. Expect your FSA or HSA plan administrator to ask for proof on every claim.

Frequently asked questions

Do red light therapy masks qualify?

A mask is treated like any other device: the use decides it. An LED mask documented for acne or a skin condition can qualify. The same mask bought for wrinkles does not.

What conditions can a clinician actually document?

Commonly acne, eczema and psoriasis, wound and post-surgical healing, and joint or muscle pain. General fatigue, aging and appearance are not documentable reasons.

Is anti-aging or cosmetic use eligible?

No. Cosmetic procedures and products are excluded, and no letter changes that. See acne treatment for the line between cosmetic and medical skin care.
