An HSA is a special, tax-advantaged savings account you can use to pay for qualified medical expenses. You deposit money in your HSA, where it earns interest tax-free. Funds are not taxed when withdrawn for qualified medical expenses.
If your HSA custodian has provided you with a checkbook or debit card, you can pay your physician directly from the account. If the custodian does not offer these features, you can pay the physician with your own money and reimburse yourself for the expense from the account after your visit.
