Health Savings Accounts (HSAs) let you set aside pre-tax dollars to pay for qualified health expenses. HSAs are linked to high-deductible health plans, and funds in these accounts roll over year after year. Flexible Spending Accounts (FSAs) allow you to use pre-tax dollars for eligible health expenses. Unlike HSAs, FSAs are not tied to a specific health plan and often require you to use the funds within the calendar year. FSAs are typically provided by employers.

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.

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.
