Which enrollment period allows individuals to enroll in Medicare Part B from January 1 to March 31?

The General Enrollment Period is specifically designed for individuals who did not sign up for Medicare Part B when they were first eligible. It takes place annually from January 1 to March 31, allowing eligible individuals to enroll in Part B coverage. This period is crucial for those who may have missed their Initial Enrollment Period or who are coming off of employer-sponsored insurance and need to transition to Medicare.

During this timeframe, enrollees will start their coverage on July 1 of the same year. It's important to note that those who enroll during the General Enrollment Period may face late enrollment penalties, which can increase their Part B premiums for as long as they have Medicare.

The other enrollment periods serve different purposes. The Special Enrollment Period allows for enrollment under certain circumstances, such as losing other health coverage. The Open Enrollment Period typically refers to the timeframe for Medicare Advantage and prescription drug coverage, while the Annual Enrollment Period is designated for existing beneficiaries to review and change their existing plans, rather than for first-time enrollment in Medicare Part B.
