Good to know
Everything you need to know about paying with your HSA or FSA, Letters of Medical Necessity and reimbursement.
Flex is a payment partner that lets you use your HSA or FSA debit card to buy eligible products with pre-tax dollars. Baby Brezza has partnered with Flex so that qualifying customers can check out with their HSA/FSA card and save an estimated 30–40% compared to paying with post-tax money.
Add eligible items to your cart and choose “Flex – Pay with HSA/FSA” at checkout, then enter your HSA/FSA card. If you don't see the option, you may be signed in to Shop Pay. Log out or check out as a guest.
Select the Flex option, pay with a regular credit card, and download an itemized receipt from the Flex portal afterwards. You can submit that receipt to your plan administrator for reimbursement.
The Flex option is hidden when you are logged in to Shop Pay. Log out of Shop Pay or check out in an incognito/private window.
The most common reason is insufficient funds. Please confirm your available balance with your plan administrator and try again.
No. If one account does not have enough funds, pay the remainder with a credit card through Flex and submit the itemized receipt to your plan for reimbursement.
Yes. Sales tax on eligible items is also covered. In split carts the tax is divided across payment methods by item.
Some products require a letter from a licensed provider stating that the item helps treat or manage a medical condition. Flex runs a quick chat-based telehealth consultation at checkout and typically issues the letter within a couple of hours.
The IRS requires a Letter of Medical Necessity for certain purchases to qualify as HSA/FSA eligible. The short telehealth questionnaire at checkout collects only what is needed to issue the letter.
Keep it for your records for at least three years in case of an IRS audit. Some FSA administrators may also ask for it when processing a claim.
Log in to the Flex consumer portal with the email you used at checkout to download your documents, or contact Flex support.
Contact Flex support with your order details and they will reissue the letter with the corrected information.
Check eligibility with your plan administrator before purchasing; employer FSA plans can be stricter than IRS rules. If you believe a claim was wrongly denied, send us your administrator's response and we will help.
It depends on your plan. Most FSAs require the purchase to be made within the coverage year. HSAs generally allow reimbursement in any year.
HSA itemized receipts can be used at any time. FSAs usually require the purchase to fall within the plan year, although some allow a short grace period. Contact us if you need an itemized receipt for a past order.
