Blue Advantage is a Medicare-approved Medicare Advantage plan. Also known as Medicare Part C, Medicare Advantage plans like Blue Advantage provide members with their Medicare Part A and Part B coverage plus extra benefits, and generally feature lower copayments than Original Medicare does. Unlike Original Medicare, with a Blue Advantage plan, medical, hospital and prescription drug coverage is included. Instead of relying on Medicare Parts A and B to cover hospital and medical expenses, and a separate Part D plan for prescription drugs, everything is conveniently covered by one simple and effective plan.
