Frequently Asked Questions

Common questions about Flex HSA/FSA Payments

Health savings accounts (HSAs) and flexible spending accounts (FSAs) are tax advantaged accounts that can be used for health related purchases.

Traditionally, health expenses are limited to spending at healthcare facilities (think doctor’s office, dentist office etc) or on a specific list of items, usually available at a pharmacy like CVS or Walgreens. Flex works with wellness partners to enable you to spend your HSA/FSA money with them as well. Our partners include sleep, fitness, and meditation apps, nutrition programs, in person gyms, wearables and even medical tourism! Reach out to support@withflex.com if you’re interested in learning more!

A Letter of Medical Necessity is a note from a licensed healthcare provider stating that a product is needed to treat or manage a medical condition. Some products require this documentation to qualify for HSA or FSA payment, as required by the IRS. Flex makes this process simple by offering asynchronous telehealth visits directly at checkout. If a Letter is needed, customers can complete a quick consultation and receive approval to pay with HSA/FSA. Within 24 hours of purchase, Flex will email an itemized receipt and any necessary documentation.
