How to pay with pre-tax HSA/FSA funds
Checkout
Find the Truemed logo during checkout. Exit the "Shop Pay" pop-up if prompted.
Complete health assessment
Take a quick, private health survey. A licensed provider will review your answers to determine eligibility.
Make your purchase
Pay with your HSA/FSA card or a credit card. If you use a regular credit card, follow the guide included with your LMN to submit your purchase for reimbursement.
Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) let you set aside pre-tax dollars for healthcare costs. However, their applications have traditionally been limited to expenses such as co-pays, deductibles, and basic medical supplies like sunscreen and bandages—leaving many meaningful health investments out of reach.
There is a movement redefining healthcare, focusing on proactive, root-cause solutions like fitness, nutrition, and innovative health technology. When you shop with Truemed merchants, you can seamlessly qualify for a Letter of Medical Necessity (LMN), enabling you to use pre-tax HSA/FSA funds for these transformative health interventions—saving you an average of 30%.
