The Medicare Advantage Open Enrollment Period ended March 31, 2009; however certain Medicare beneficiaries are allowed to change their Medicare plan choice before November 15th. These include:
* All beneficiaries who receive Extra Help (even Partial Extra Help). They can change their Medicare Part D plan choice (including their MA-PD plan choice) at any time of the year, to be effective the first of the following month.
* ALL EPIC members are entitled to a one-time Special Enrollment Period (each year) to switch their Part D plan choice.
* Beneficiaries (over 65) who enrolled in a Medicare Advantage plan during their Initial Enrollment Period, or any beneficiary who dropped their Medigap plan to enroll in a Medicare Advantage plan for the first time, have a 12-month trial period in which they can return to Original Medicare (with or without a Part D plan).
