What Is Medicare's Typical Coinsurance? 
For most situations , the Medicare coinsurance percentage is 80 % following the deductible . Keep in mind that it is 80 % of the Medicare approved amount , not the amount billed by doctor or medical provider . Under Medicare Part A -LRB- hospital -RRB- portion you have what I would consider a daily copay after the first 60 days but Medicare refers to it as coinsurance .
