如果换地区要通知 moving out of your current plan‘s service area

No, you don't need to notify the old insurance company directly when you switch Medicare Advantage plans during a valid enrollment period

. Your new plan will handle the disenrollment from your old plan automatically when your new coverage becomes effective.

The only exception is if you are moving out of your current plan's service area, as they may need to be notified to prevent them from dropping you from coverage (which could lead to a loss of benefits), according to AARP.
