HSA/FSA Payment FAQs

What is Flex and what is their relationship with Sleep Doctor?

Sleep Doctor 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 home sleep tests, mattresses, pillows, and more with pre-tax dollars, resulting in net savings of 30-40%, depending on your tax bracket.

How do I pay with my HSA or FSA card?

To use your HSA or FSA debit card, add products to your cart as usual. At checkout, select “Flex | Pay with HSA/FSA” as your payment option, enter your HSA or FSA debit card, and complete your checkout as usual. If you don’t see “Flex | Pay with HSA/FSA,” you may be in Shop Pay. Select “checkout as guest” to view more payment options.

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.

Why can't I see Flex as a payment method?

The key here is to make sure you are logged out of ShopPay. One of the easiest ways to do this is to go through checkout in an incognito window.

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.

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.

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.

Letter of Medical Necessity FAQs

What is a Letter of Medical Necessity?

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), Flex facilitates a chat-based consultation that generates the Letter in real time.

Why do I need to provide Sleep Doctor with health information?

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

This may be a time zone issue. Contact our support team at contact@sleepdoctor.com and 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 a product name/NPI number/other info 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 FAQs

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 (contact@sleepdoctor.com) 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 I 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.
