General HSA/FSA Questions

What is a qualified customer?

The IRS oversees HSA and FSA eligibility and dictates that a customer must have a medical condition or disease they seek to treat or manage with BIOGENA ONE products.

Customers must have documentation, also called a Letter of Medical Necessity, that confirms their eligibility. Not to worry, we have partnered with Flex to make this a quick and easy process for you.

How do I use my HSA/FSA to pay?

At checkout, select Flex | Pay with HSA/FSA as your payment option. You will be prompted to complete a brief Telehealth consult to confirm your eligibility to pay with HSA/FSA. From there, enter your HSA or FSA debit card details and complete your checkout as usual.

Within 24 hours of your purchase, Flex will email you both a Letter of Medical Necessity as well as an itemized receipt. Keep these documents for your records should your HSA/FSA provider or the IRS require additional documentation.

What is Flex and what is their relationship with BIOGENA ONE?

BIOGENA has partnered with Flex to allow you to use your Health Savings Account (HSA) or Flexible Spending Account (FSA). This means you can now use your HSA or FSA debit card to buy BIOGENA ONE with pre-tax dollars, resulting in net savings of 30-40%, depending on your tax bracket.

What if I don’t have my HSA/FSA card available?

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.

Why is my HSA/FSA card being declined?

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.

I submitted my Flex itemized receipt for reimbursement and my FSA requires more information.

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

Help! I didn’t receive an email from Flex with my itemized receipt and/or letter of medical necessity. What should I do?

Please check your spam folder, as sometimes emails from notifications@withflex.com may be automatically filtered as spam by some email service providers. If you still can’t find it, please email support@withflex.com and let them know the email address associated with your order.

I would like to use multiple HSA/FSA cards to pay for an item. Can I do that?

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.

My purchase receipt from [BRAND] has a different number than what my FSA was charged. How can we resolve it?

Thanks for reaching out, and apologies for the discrepancy. We'll review the charges and get back to you with details of the likely refund shortly.

Is sales tax covered by HSA/FSA funds, or is it treated separately?

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.

Letter of Medical Necessity Questions

What is a Letter of Medical Necessity?

A letter is essentially a note from a doctor stating that you are purchasing an item to treat or manage a medical condition. More details can be found here.

Why do I need to provide [BIOGENA with health information?

In order to qualify to use your HSA or FSA card for BIOGENA ONE, the IRS requires you to have a Letter of Medical Necessity.

BIOGENA 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.

Do I need to do anything with my Letter of Medical Necessity?

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.

Help! I mistakenly entered my name and/or date of birth and need to get an updated letter. Who can I reach out to?

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

The date on my Letter of Medical Necessity is one day different from my receipt.

Thanks for letting us know! 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.

My FSA says I need BIOGENA ONE added to my Letter for approval.

Generally, we’re not able to accommodate one-off requests, but we will reach out to our partners at Flex and see if we can accommodate your request.

Help! I did not receive an itemized receipt and/or Letter of Medical Necessity from Flex. What should I do?

Please check your spam folder, as sometimes emails from notifications@withflex.com may be automatically filtered as spam by some email service providers. If you still can’t find it, please email support@withflex.com and let them know the email address associated with your order.

HSA/FSA Reimbursement Questions

My HSA/FSA Claim was denied. What should I do?

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.

Can a customer purchase a product now and apply for FSA reimbursement in the next calendar year?

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.

Can old (non-Flex) customers use their order confirmation email to apply for HSA/FSA reimbursement?

Unfortunately, for purchases made without using Flex(opens in a new tab) 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.
