[Copy] At checkout, select Flex | Pay with HSA/FSA as your payment option. You will be prompted to complete a brief telehealth consult to confirm your eligibility to pay with HSA/FSA. From there, enter your HSA or FSA debit card details and complete your checkout as usual. If you don’t have your HSA or FSA debit card handy, you can also complete the checkout with a regular credit or debit card.

Within 2 hours of your purchase, Flex will email you both a Letter of Medical Necessity as well as an itemized receipt. Keep these documents for your records should your HSA/FSA provider or the IRS require additional documentation.
