What is an HSA/FSA account?

Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) are tax-free accounts that can be used to pay for qualified health expenses. These accounts are usually set up and managed by an HSA or FSA administrator, and you should have access to said HSA/FSA administrator through your employer (ask your HR department!).

HSAs are typically associated with a high-deductible health plan, and funds do not expire. FSAs are independent of your health plan, and funds elections occur in October-November each year for the following calendar year. FSA funds expire every calendar year.

HSAs and FSAs are not available outside of the US, and self-employed individuals (who do not have an HSA from a previous employment) do not qualify for HSAs or FSAs.

What is Trumed?

Truemed partners with merchants and brands to enable qualified customers to use HSA/FSA funds on qualified products and services that are used to treat, mitigate, or prevent a diagnosed medical condition. Truemed partners with a network of individual practitioners who evaluate customers’ eligibility and issue Letters of Medical Necessity to qualifying customers, thereby saving customers money on legitimate medical expenditures.

Truemed is backed by best-in-class investors, including functional medicine pioneer Mark Hyman and founders from Thrive Market, Eight Sleep and Levels.

How does using my HSA/FSA account save me money?

HSA/FSA accounts were created so individuals could use pre-tax money to pay for expenses used to treat, mitigate, or prevent a diagnosed medical condition. Because HSA/FSAs use pre-tax money, you’re getting more purchasing power for your dollars. Rather than pay taxes on income and then spend it on health items, qualified customers can use pre-tax funds to invest in their health.

What is a Letter of Medical Necessity?

In order to determine whether certain products or services are legitimate expenses for treating, mitigating, or preventing a diagnosed medical condition, HSA/FSA plan administrators often require a letter from a licensed practitioner. This letter is called a “Letter of Medical Necessity.”

Can I use my HSA/FSA card at checkout?

Yes! You can use your HSA/FSA card. Once you pay with your card and complete the survey, all you need to do is keep an eye out for the Letter of Medical Necessity that we will send you, and hold onto it for the next 3 years.

Can I use my regular credit card at checkout?

If you prefer to use your regular credit card, you are welcome to do that and we will send you instructions for how to submit for reimbursement from your administrator. Check out this article to get a comprehensive understanding of the reimbursement process.

How long does it take for me to receive my Letter of Medical Necessity?

Generally it takes 24-48 hours. If you aren’t seeing your letter in your inbox, check spam, then reach out to us at for help!
