(BPT) - Medicare comes with important decisions - and areas that often need explanation. For instance, many people think Medicare is free or that it covers everything, including long-term care and routine dental or vision - but that's not the case. Enrollment isn't automatic for everyone, and missing your Initial Enrollment Period could lead to penalties unless you qualify for a Special Enrollment Period. Understanding what Medicare actually covers - and when and how to enroll - can help you avoid surprises and choose the right plan for your needs.
