Medicare Part A Based on Age for People Who Must Pay a Premium
People who must pay a premium for Part A do not automatically get Medicare when they turn 65. They must:
File an application to enroll by contacting the Social Security Administration;
Enroll during a valid enrollment period; and
Also enroll in or already have Part B.
To keep premium Part A, the person must continue to pay all monthly premiums and stay enrolled in Part B. This means that the person must pay both the premium for Part B and the premium for Part A timely to keep this coverage.
Premium Part A coverage begins the month following the month of enrollment.
