Medicare Enrollment Periods Practice Test

During the Open Enrollment Period (OEP), which runs from January 1 to March 31 each year, individuals have specific restrictions on the types of enrollments they can complete. It's important to understand that the OEP is primarily intended for those who are already enrolled in a Medicare Advantage (MA) plan.

Individuals are not allowed to make changes or enroll in any Medicare Advantage plans, stand-alone Medicare Part D plans (PDPs), or Medicare Advantage Plans with prescription drug coverage (MAPDs) unless they are already in a plan. This means that:

- To change to a different MA plan, a person must be enrolled in an existing MA plan first to utilize the OEP.

- Enrolling in an MAPD also requires prior enrollment in a plan, since MAPDs serve both Medicare Advantage and drug coverage.

- Similarly, enrolling in a PDP is restricted under the OEP for those not already enrolled in a Medicare plan.

Thus, all of these enrollment activities (changing plans, enrolling in an MAPD, or enrolling in a PDP) cannot be executed during the OEP by someone who is not already in a Medicare plan. This makes the correct answer comprehensive, indicating that none of these activities can be completed during the OEP for individuals
