Final answer:
Medicare Part B typically pays 80% of the approved medical bill amount after the beneficiary meets the annual deductible, leaving the beneficiary responsible for the remaining 20% as copayment.
Step-by-step explanation:
The question relates to Medicare coverage and specifically asks what percentage of an approved medical bill Medicare will pay once the deductible has been met. Under Medicare Part B, which covers doctor's services, outpatient care, and other medical services that Part A does not cover, Medicare typically pays 80% of the approved bill.
This is after the beneficiary has paid the deductible, which is an annual amount. Following that, for covered services, the beneficiary is usually responsible for a 20% copayment of the approved amount. It is important to note that some services may have different cost-sharing amounts, and there can be variations based on whether a provider accepts Medicare assignment.
