Real reviews from real people
“I had no idea my gym could be covered. The quiz flagged that my BMI qualified, a real physician reviewed it, and I got my letter the same day. A good chunk of what I'd already spent came back.”
“What sold me was that an actual board-certified physician reviewed my case — his NPI and license were right on the letter. My FSA reimbursed my membership.”
“My doctor had already told me to exercise for my blood pressure — I just didn't know I could use pre-tax dollars for it. The letter came back signed and my plan reimbursed it.”
“The whole thing took under ten minutes. I used my HSA on an Oura ring and my standing desk, and both were reimbursed without a single follow-up question.”
“I was skeptical it would actually hold up, but the QR code verification on the letter made my FSA admin comfortable instantly. Money back in two weeks.”
“My personal training sessions add up fast. Having them covered pre-tax meant I could keep going through the winter. The letter arrived the same afternoon I applied.”
“After my prediabetes diagnosis my doctor wanted me moving more. MedSlip turned that into a covered gym membership in one short questionnaire. Genuinely easy.”

Contact our team →What is MedSlip?
MedSlip is an online physician service that provides Letters of Medical Necessity (LMNs). A board-certified physician reviews your health profile and, when medically appropriate, issues a signed letter that may help you use HSA or FSA funds for eligible wellness expenses such as gym memberships, massage therapy, exercise equipment, ergonomic chairs, and wearables.
What is a Letter of Medical Necessity?
A Letter of Medical Necessity (LMN) is a physician-signed document explaining why a product or service is medically appropriate for treating or managing a health condition. Many HSA and FSA administrators require an LMN before reimbursing expenses that are not automatically eligible.
Can I use my HSA or FSA for a gym membership?
In some situations, yes. A gym membership may qualify for reimbursement when a physician determines it is medically appropriate and issues a Letter of Medical Necessity. Final reimbursement decisions are made by your HSA or FSA administrator.
Is Oura Ring HSA or FSA eligible?
Wearables such as Oura Ring, WHOOP, and certain smart devices may qualify when they are part of a physician-recommended treatment plan and supported by a Letter of Medical Necessity.
Does massage therapy qualify for HSA or FSA reimbursement?
Massage therapy may be eligible when prescribed to help manage chronic pain, musculoskeletal disorders, stress-related conditions, and other qualifying medical concerns.
Do I qualify?
Qualification depends on your health profile and physician review. Every case is individually evaluated, and not everyone will qualify for a Letter of Medical Necessity.
Who signs the letter?
A board-certified physician licensed in your state reviews and signs every MedSlip letter.
What happens if I don't qualify?
If a physician determines that a Letter of Medical Necessity isn't clinically appropriate, one won't be issued and you won't be charged.
How much can I save?
Because HSA and FSA dollars are pre-tax, many members save hundreds of dollars annually on eligible wellness expenses.
