KPAX is now HSA/FSA Eligible

KPAX has partnered with Truemed to allow you to use your Health Savings Account (HSA) or Flexible Spending Account (FSA). This means you may be eligible to buy your favorite KPAX products with pre-tax dollars, resulting in net savings of 30-40%.

HSAs and FSAs were created for you to spend tax-advantaged dollars on products and services that can alleviate or prevent specific medical conditions and TrueMed is making it easy to do just that.

All you have to do is add products to your cart, select TrueMed as your payment option at checkout, enter your HSA or FSA debit card, and take a quick health survey to determine eligibility. The Truemed payment option determines eligibility and enables qualified customers to pay with their HSA/FSA funds in checkout. Once you’re approved, that’s it. You’ll receive an order confirmation and effectively save 30-40% on your order.

Frequently asked questions


What is an HSA/FSA account?

Open tab

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.

Unfortunately, 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 Truemed?

Open tab

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?

Open tab

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.

An individual can contribute up to $3,850 pretax to their HSA per year, or $7,750 for a family (plus an additional $1,000 if you are at least 55 years old Individuals can contribute up to $3,050 pretax to their FSA per year (with an additional $500 in employer contributions allowed). Almost every qualified individual will save between $1,000 and $2,000, depending on their state and tax rate.

What is a Letter of Medical Necessity?

Open tab

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.”

Why should I use my HSA/FSA funds with Truemed’s partner brands?

Open tab

Using your HSA/FSA funds on eligible products or services sold by Truemed’s partner brands can result in significant savings. HSA/FSA accounts allow you to use pre-tax dollars to purchase products and services to treat, mitigate, or prevent the specific medical conditions that you have been diagnosed with.

I don’t have an HSA/FSA. Can I still benefit from Truemed?

Open tab

Unfortunately, Truemed’s services are for individuals who have HSA or FSA accounts (or plan to fund one during open enrollment). We encourage you to ask your employer about information on your HSA or FSA!

How long does HSA or FSA reimbursement take?

Open tab

For most FSA/HSA administrators, your expenses will be approved within days when you submit your claim for reimbursement along with your receipt and a Letter of Medical Necessity. The exact timing will vary based on your administrator.

Can I use Truemed’s services for past purchases?

Open tab

While this depends on your specific HSA or FSA administrator’s policies, we advise that you only submit expenses incurred on or after the date listed on your Letter of Medical Necessity.

Do I need to take Truemed’s survey every time I make a purchase from a partner brand?

Open tab

If you have already received an Letter of Medical Necessity for purchasing specific products from a merchant, you do not need to complete Truemed’s survey again so long as your Letter of Medical Necessity remains valid. Letters of Medical Necessity are typically valid for 12 months after they are first issued. You do still need to submit your receipts for reimbursement with your HSA/FSA administrator.

HSA/FSA Account Questions

I don’t have enough funds in my HSA/FSA account to cover the entire purchase. Can I still use Truemed?

Open tab

You can occasionally request a split invoice from the merchant that you are making a purchase from, but like your normal bank account, you generally need to have the funds to cover the purchase to avoid a rejection.

What if my HSA/FSA payment is rejected by my administrator?

Open tab

Please contact us at so we can help you troubleshoot the issue. HSA/FSA plan administrators often have detailed requirements, so it may be as simple as re-issuing your Letter of Medical Necessity using the administrator’s form.

What if I haven’t contributed to my HSA/FSA. Will I still be able to maximize my savings?

Open tab

For most Americans, open enrollment is in the last four months of the year. Simply elect to increase contributions to your HSA or FSA during this time and you can begin shopping with Truemed merchant partners. Starting on January 1st, qualified individuals will be able to spend their entire HSA or FSA amount on products that a licensed practitioner recommends to treat, mitigate, or prevent a specific, diagnosed medical condition. These funds will be pulled from your paycheck, prior to tax withholding, by your HSA/FSA administrator in equal installments through the year.
