Final answer:
The client cannot switch to another MAPD plan during the IEP window if the plan is already effective.
Step-by-step explanation:
The correct answer is False.
During the Initial Enrollment Period (IEP) for Medicare Advantage Prescription Drug (MAPD) plans, clients have the opportunity to select a plan that meets their needs.
However, once the plan becomes effective, the client generally cannot switch to another MAPD plan until the Annual Enrollment Period (AEP) which occurs from October 15th to December 7th each year, unless they qualify for a Special Enrollment Period (SEP).
