A: If you go to a non-participating provider who doesn’t accept assignment for Medicare covered
services, they can charge you more than the Medicare-approved amount, but there’s a
limit called “the limiting charge” or “excess charge.” The provider can only charge you up to 15
percent over the amount that non-participating providers are paid. Non-participating providers
are paid 95 percent of the fee schedule amount. The excess charge applies only to certain
Medicare-covered services and doesn’t apply to some supplies and durable medical equipment.
Non-participating providers who charge excess charges are relatively rare, but it is still worth
checking whether your healthcare provider accepts assignment or participates in Medicare.
