I want to use two HSA/FSA cards to pay my purchase at Mira. Is there a provision for that? Or is there a workaround to provide that?Updated 6 months ago

Unfortunately, this isn't a supported option today. If you have insufficient funds in a single HSA or FSA account, you can instead enter a credit card on the Flex checkout page. You will receive their itemized receipt and Letter of Medical Necessity from Flex and you can use those documents to submit for reimbursement for whatever the available balance is in the account.
