Yes. MA plans offered in your area are required to accept you unless they are closed to all new members. If they are closed, they must accept you during the annual election period from October 15 to December 7 each year (except if you have end-stage renal disease). Some other situations in which a plan must accept you: You just turned 65 and went on Medicare. You had coverage under an MA plan and moved out of that service area. You were in an MA plan that did not renew its contract with Medicare or its contract with your provider(s).
