En español | Coinsurance is the amount you may be required to pay for services after you pay any deductibles. This could be a percentage (such as 20 percent) of the Medicare-approved amount or a fixed dollar amount. You have to pay this amount after you pay the deductible for Part A and/or Part B.

Within the Medicare Part D prescription drug benefit, each prescription filled may require either coinsurance (a percentage of the drug cost) or a fixed amount regardless of the drug cost.
