Do I need to enroll in a Medicare Advantage plan (Part C)?

You don’t need to. It’s your choice to decide if you’d like to be on Original Medicare or sign up for Medicare Advantage Plan (Part C) or Medicare Supplement (Medigap). Be mindful of the deductibles and copayments if you choose to stay on Original Medicare with no additional medicare insurance coverage. As well as the late enrollment penalty if you don’t have creditable prescription drug coverage.
