If you are still covered by your HDHP and have not met your policy deductible, you will be responsible for 100% of the amount agreed to be paid by your insurance policy to the physician. Your physician may ask you to pay for the services provided before you leave the office. 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.
If your physician does not ask for payment at the time of service, the physician should submit a claim to your insurance company, and the insurance company will apply any discounts based on their contract with the physician. You should then receive an “Explanation of Benefits” from your insurance plan stating how much the negotiated payment amount is, and that you are responsible for 100% of this negotiated amount. If you have not already made any payment to the physician for the services provided, the physician will then send you a bill for payment.
