The Problem
Most customers don’t realize that sleep wellness products may qualify for HSA/FSA spending when shopping, and will frequently drop-off from checkout if they think they require a Letter of Medical Necessity for their products and can’t get one now.

FAQs

What is HSA/FSA?
Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs) are tax-advantaged accounts that allow individuals to set aside pre-tax dollars for qualified medical expenses. Many Americans use these accounts to pay for everyday health-related purchases—including eligible sleep wellness products like mattresses, bedding, sleep tech, and clinical sleep aids.
How do I know if the sleep products I sell are HSA/FSA eligible?
Flex automatically verifies the eligibility of each sleep wellness product you sell, and will flag which ones can be made HSA/FSA eligible—with or without a Letter of Medical Necessity (LMN).
Can Flex help customers get a Letter of Medical Necessity (LMN) my for sleep wellness products during checkout?
Yes. If a skincare purchase requires a Letter of Medical Necessity (LMN), Flex prompt a telehealth consultation during checkout. A healthcare practitioner reviews the customer’s information and, if approved, the LMN is typically emailed within about 2 hours.
