Frequently Asked Questions

If you can’t find what you’re looking for, please reach out to support@withflex.com.
Yes. Every Home product in the Flex Marketplace is HSA/FSA eligible, though some require a Letter of Medical Necessity (LMN) before you can spend pre-tax dollars on them. If one does, Flex walks you through a brief chat-based consultation at checkout to confirm eligibility. You can pay with your HSA/FSA card, split the payment with a credit or debit card, or pay in full and submit the itemized receipt Flex sends you for reimbursement.
At checkout, select "Flex | Pay with HSA/FSA." Some products require a Letter of Medical Necessity. Complete a brief chat-based telehealth consultation to confirm eligibility if required. Enter your HSA/FSA card details and complete your purchase. If you don’t have your HSA/FSA card available, use a regular credit or debit card. Submit your Letter of Medical Necessity and itemized receipt (provided by Flex) to your HSA/FSA administrator for reimbursement.
HSA and FSA cards are debit cards, and the most common reason for declines is insufficient funds. Reach out to your HSA/FSA administrator to confirm your balance.
If you don’t have your HSA or FSA card handy, still select “Flex - Pay with HSA/FSA” as your payment method. Enter your credit card information and Flex will email you an itemized receipt to submit for reimbursement.
All products shown in the Flex Marketplace are HSA/FSA eligible, some may require a Letter of Medical Necessity (LMN). Some brands may also offer additional eligible items on their website. When shopping directly on a site, look for HSA/FSA messaging on individual product pages. Flex accepts HSA/FSA cards, credit/debit cards, and split payments. Select Flex at checkout to pay for your purchase.
