Equi.Life has partnered with Flex, one of the leaders in the online processing of HSA/FSA payments, to allow you to use your Health Savings Account (HSA) or Flexible Spending Account (FSA) when purchasing on Equi.Life. This means you can now use your HSA or FSA debit card to buy supplements, protocols and lab tests with pre-tax dollars, resulting in net savings of 30-40%, depending on your tax bracket.

For One-Time Purchases:

Step 1: Checkout

Select “Flex | Pay with HSA/FSA" as a payment method. If this option is not visible, be sure you select "Check out as Guest"

Step 2: Confirm Eligibility

If prompted, take a quick, private health survey. A licensed provider will review your answers to determine eligibility.

Step 3: Complete your Purchase

Enter your HSA/FSA payment details. Flex will email you an itemized receipt and a letter of medical necessity (if applicable).

For Subscription Purchases:

Step 1: Complete your purchase

Pay with your regular credit card. After your purchase, check the confirmation page or confirmation email for a link to the Flex survey.

Step 2: Confirm Eligibility

From the order confirmation page or email, click “Get Reimbursed” to take a quick, private health survey. A licensed provider will review your answers to determine eligibility.

Step 3: Submit for Reimbursement

Follow the steps emailed with your Letter of Medical Necessity to submit your purchase for HSA/FSA reimbursement.

Some products require documentation from a licensed healthcare provider stating that the item is necessary to treat or manage a specific medical condition. If the product requires a Letter of Medical Necessity (LOMN), EquiLife facilitates a chat-based consultation with Flex, our HSA/FSA partner, within the Equi.Life checkout that generates your Letter in real time.

If you don’t have your HSA or FSA card handy, still select “Flex | Pay with HSA/FSA” as your payment method. Enter your credit card information and Flex will email you an itemized receipt to submit for reimbursement.

HSA/FSA cards are debit cards, and the most common reason for declines is insufficient funds. Reach out to your HSA/FSA administrator to confirm your balance.

Please forward us the request from your FSA, and we will work with the Flex team to issue you a new receipt.

No, unfortunately, this isn’t a supported feature right now. If there are insufficient funds in a single HSA or FSA account, you can instead enter a credit card on the Flex checkout page. You will receive an itemized receipt and/or Letter of Medical Necessity from Flex, which you can submit for reimbursement.

Sales tax for eligible items is also covered by HSA/FSA funds. If the customer has a split cart, the tax will be divided among the cards based on the items.

Some products require documentation from a licensed healthcare provider stating that the item is necessary to treat or manage a specific medical condition. If the product requires a Letter of Medical Necessity (LOMN), EquiLife facilitates a chat-based consultation with our HSA/FSA partner within the Equi.Life checkout that generates your Letter in real time.

In order to qualify to use your HSA or FSA card for health related products, the IRS requires you to have a Letter of Medical Necessity. Equi.Life has partnered with Flex to enable asynchronous telehealth visits as part of our checkout. Within 24 hours of your purchase, Flex will email you both an itemized receipt.

You should keep it on file for at least three years in the event of an IRS audit of your HSA or FSA account. Occasionally, FSAs may ask for the Letter to confirm the eligibility of your purchase.

You will need to renew your Letter of Medical Necessity (LOMN) a year from when it was first generated. Your Letter of Medical Necessity is valid for a rolling 12 month period before it needs to be renewed.

Please email support@withflex.com and they will reach out to their telehealth team to reprocess and send your corrected Letter of Medical Necessity.

Please send an email to customer support at support@equi.life. This may be a time zone issue. We’ll reach out to our partners at Flex to see if they can reissue the Letter with an updated date.

We strongly recommend checking with your HSA/FSA provider to see if a purchase is eligible prior to completing the purchase. However, if you believe your claim has been wrongly denied, please send over any response from your HSA/FSA provider to us so we can share it with Flex and receive guidance on the next best steps to take. Please note that employer-sponsored FSAs can determine what products are eligible beyond the IRS’s guidelines, so it’s extremely important to check prior to purchase.

The ability to apply for FSA reimbursement in a future calendar year depends on the policy of the specific FSA provider. Most FSA administrators require that the purchase be made during the time of coverage. For example, if the FSA coverage is for 2025, all purchases typically need to be made and/or submitted for reimbursement within that coverage period. However, some administrators may have more flexible rules regarding the timing of when the expense occurred. We recommend that customers review their plan policy to confirm the details.

Note: Health Savings Accounts (HSAs) are different and generally allow for reimbursement at any time, even in future years.

Unfortunately, for purchases made without using Flex in the checkout to receive an itemized receipt, it may be difficult to apply for reimbursement. For Health Savings Accounts (HSAs), consumers can use an itemized receipt for reimbursement anytime after they have made the purchase, even if it is many years later. For Flexible Spending Accounts (FSAs), most accounts require that the purchase was made in the calendar year during which the consumer had the FSA, as FSAs typically do not roll over. Some FSAs offer a buffer window, allowing customers additional time to submit receipts for expenses incurred during the previous calendar year.

Sorry, no. HSA/FSA funds may only be used for a current transaction.
