Head to Flex’s site and finish a 2-minute chat with a licensed provider. If eligible, you’ll get a Letter of Medical Necessity in under two hours.
Sign up for your MTNTOUGH+ Membership with any standard payment method (don’t use your HSA/FSA card at checkout).
Submit your Letter of Medical Necessity and MTNTOUGH receipt to your HSA/FSA provider to get your money back.
Visit our Flex reimbursement page to begin. The consultation’s only $15 (HSA/FSA eligible), and your Letter covers MTNTOUGH expenses for a full year. Heads-up: Complete the consultation first—only same-day or future payments qualify.
Already in the crew? You can tap into HSA/FSA savings too! If you’re on a monthly plan, get your Letter of Medical Necessity and submit it with your receipt to your HSA/FSA provider each month for reimbursement—no need to cancel. Or, switch to an annual plan for a simpler process. Annual subscribers can cancel and repurchase to use the Letter right away, or wait until your renewal date and submit your receipt and Letter for reimbursement.
