Medicare has four important parts when you begin your enrollment. It is important to understand the difference between Medicare Part A, Medicare Part B, Medicare Part C, and Medicare Part D. Medicare Part A and Medicare Part B benefits are the same across the board, but under Medicare Part C, things change based on whether you choose Original Medicare with a Medicare Supplement plan, or a Medicare advantage plan.

It is important to understand not only when to apply for medicare enrollment, but also know what your Medicare coverage entails.
