What is NOT a part of Original Medicare?

Original Medicare consists of two main components: Part A, which covers hospital insurance, and Part B, which provides medical insurance. Together, these parts form the foundation of Medicare coverage for eligible individuals aged 65 and older or certain younger people with disabilities.

Part C, known as Medicare Advantage, is not included in Original Medicare. Instead, it is an alternative way to receive Medicare benefits through private insurance companies that contract with Medicare. Medicare Advantage plans often provide additional benefits and include coverage for services not typically covered by Original Medicare.

Part D focuses on prescription drug coverage and is also separate from Original Medicare. While it can be added to the Original Medicare pair (Parts A and B), it does not form a part of it.

Therefore, the inclusion of Part C in the list signifies that it is the correct answer as it functions independently from Original Medicare, highlighting its distinction in the structure of Medicare options available to beneficiaries.
