The Merchant Category Code (MCC) for accepting Health Savings Account (HSA) and Flexible Spending Account (FSA) cards is 8099. This code is designated for Health Practitioners and Medical Services that are not classified elsewhere. It is important for businesses to have this MCC assigned to ensure they can accept HSA and FSA payments.
Accepting HSA/FSA Cards using Practice Better Payments (powered by Stripe)
More details on accepting HSA/FSA cards can be found on the Stripe website:
HSA and FSA cards require that your business have a special classification (called an MCC) set so that the card companies know that your products and services are directly related to a patient’s medical needs.
If your business needs to accept HSA or FSA cards, please get in touch so we can make sure that your account is properly configured to accept these card types.
And bear in mind, just because an account is enabled to accept HSA or FSA payments, doesn’t guarantee a card won’t still be declined. Card issuers are still at liberty to authorize or decline any payment as they would with any other type of credit card.

If you use Square, you can accept payment using HSA and FSA cards. You will first need to contact Square to configure your account before you can accept these payments via Practice Better.

Licensed health care providers and pharmacies can process Health Savings Account (HSA) and Flexible Spending Account (FSA) cards with Square. We don’t currently support EBT or other benefits cards.
