Pay Using Your HSA/FSA Funds With Flex

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.

In order to qualify to use your HSA or FSA card for red light therapy devices, the IRS requires you to have a Letter of Medical Necessity. Vital Red Light 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.

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

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.

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.

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.

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.
