What is the MA enrollment period (MA-OEP) when members can make a one-time election annually?

The MA enrollment period, known as the MA Open Enrollment Period (MA-OEP), allows members to make a one-time election annually to change their Medicare Advantage plan. This period specifically runs from January 1st to March 31st each year. During this time, beneficiaries can make changes such as switching plans or returning to Original Medicare.

The other options do not align with the established dates for the MA-OEP. Each proposed period either starts or ends outside the designated timeframe, making them incorrect. The January 1st to March 31st timeframe is a critical enrollment window for members to reassess their healthcare coverage at the beginning of the year, ensuring they have the opportunity to adjust their plans based on their needs. Thus, the correct answer reflects the precise timing when beneficiaries can exercise this option to alter their plan selections effectively.
