Yes, you can process Health Savings Account cards and Flexible Spending Account cards using Stripe. In order to do this, you'll need to email Stripe directly and ask them to configure your account to process these types of cards. You can email Stripe at support@stripe.com.

HSA and FSA cards require that your business has a special classification (called an MCC) 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, email support@stripe.com, and they'll ask you a few pieces of information to help them get that configured for you.

Bear in mind, just because an account is enabled to accept HSA or FSA payments, doesn’t guarantee the 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.
