BALANCE BILLING - MEDICARE

A situation in which Private Fee-for-Service Plan providers (doctors or hospitals) can charge and bill you 15% more than the plan's payment amount for services.

BALANCE BILLING - SURPRISE BILLS

When a provider bills you for the balance remaining on the bill that your plan doesn't cover. This amount is the difference between the actual billed amount and the allowed amount. This happens most often when you see an out-of-network provider (non-preferred provider). These balance bill costs are in addition to what you pay out-of-pocket for out-of-network services according to your health plan coverage. An in-network provider (preferred provider) may not balance bill you for covered services.
