Medicare Part B Excess Charges? 
Physicians do have a third option besides `` Participating '' or `` Non-Participating '' . The can become a private contracting physician -LRB- opting out of Medicare -RRB- , agreeing to bill patients directly and forego any payments from Medicare to their patients or themselves . This is rare however , fewer than 1 % of all physicians are private contractors . Due to limiting charges , Medicare reimbursement penalties , and administrative collection costs , Part B excess charges are an extreme rarity and not something to be concerned with . It 's a non-issue in the states mentioned in a previous reply , and any Medicare beneficiary can make it a non-issue by checking that your services provider is a Participating provider in Medicare .
