Q. Should I enroll in Part B?
The Short Answer
If you are enrolling in Medicare and will no longer be covered under another plan, you should generally enroll in Part B. This will trigger your Open Enrollment period during which you should make decisions regarding any additional coverage.
When you first enroll in Medicare Part B, you start your initial six-month Open Enrollment period. During this time, no Medicare supplement insurance or Medicare Advantage plan can deny you coverage, so it is an important time to find the right coverage for you.
