The way Medicare Claims are processed depends on the type of Medicare Service. In this post we will consider four Medicare Services: Original Medicare (Part A and B), the Medicare Advantage Plan (MA), the Part D Prescription Drug Plan, and Medicare Supplement (Medigap) Plan. Keep in mind that these are not exclusive and several options may coexist (e.g., Original Medicare, Part D, and Medigap).
