Will Doctors Refuse Medicare? 
Doctors CAN refuse to bill through Medicare , but will work on a cash payment . Some doctors do notlike the `` payment schedule '' of Medicare services , some see the value of serving a growing population and will bill through Medicare . We , here in CA , are finding that there are a lot of doctors not willing to bill Medicare or Medicare plans . But if you have a Medicare Supplement plan , more of the doctors will accept billing for this - not sure why , because they have to send out two bills - one to Medicare and one to the plan . Always call your preferred doctor 's billing department to ask what they acceptbefore deciding on which kind of Medicare plan you will enroll in .
