Why Enrollment Periods Matter
Medicare doesn't let you enroll or change plans whenever you want. The federal government sets specific windows — and missing them can mean permanent premium penalties, gaps in coverage, or being locked into a plan that doesn't fit your needs for an entire year. Understanding which window applies to your situation is the first step to making a smart Medicare decision.
