Mrs. Goodman, who enrolled in a Medicare Advantage Prescription Drug (MA-PD) plan during the Annual Election Period, can switch back to Original Medicare and enroll in a stand-alone prescription drug plan during the Medicare Advantage Open Enrollment Period (MA-OEP), which runs from January 1 to March 31 each year. During this period, she may disenroll from her MA-PD plan and return to Original Medicare. At the same time, she can enroll in a separate Medicare Part D prescription drug plan. This enrollment change will be effective the first day of the month following the plan’s receipt of her enrollment request. She only gets one such enrollment change during the MA- OEP, so she should consider her options carefully. It is also important to advise her to enroll in the stand-alone Part D plan as close as possible to the date she disenrolls from the MA-PD plan to avoid any gap in prescription drug coverage. Until the disenrollment is effective, she must continue to use providers in her current MA plan’s network to ensure coverage. In summary, Mrs. Goodman can make this switch during the MA Open Enrollment Period without waiting until the next Annual Election Period, and enrolling in a stand-alone Part D plan will automatically disenroll her from the MA-PD plan
