(BPT) - Each year, Medicare-eligible individuals can sign up for Medicare plans during the Annual Enrollment Period (AEP), which runs from October 15 through December 7. During this time, you can enroll in a plan for the first time. Or you can review your current plan to make sure it still meets your needs. If you don't act during this year's AEP, you'll have to wait for next year to make changes to your coverage.
