There are two parts of Medicare, Hospital Insurance and Supplemental Medical Insurance. If you were getting Medicare and cash benefits before you went to jail, your cash benefits will stop but your hospital insurance (Part A) coverage will continue. To keep your Supplemental Insurance (Part B) coverage or medial insurance that you are paying for, you must pay the premiums or your coverage will end. If your coverage ends while you are in jail because you did not pay your Medicare premiums, you will be able to enroll again during the next General Enrollment Period (January through March of each year). Your insurance coverage will start again the following year. If you reenroll, you will be responsible for any unpaid past-due premiums and your ongoing premium will be higher.
