What are the 4 parts of Medicare?
Medicare has four parts: A, B, C, and D. Original Medicare includes Medicare Part A (hospital care) and Part B (doctor visits).
Many people find they need more coverage than what Original Medicare provides, such as dental, vision, hearing, or prescription drug coverage. This is where Medicare Part C (Medicare Advantage) and Part D (prescription drug) plans come in.
After you enroll in Original Medicare, you can sign up for Part C and/or Part D through a private insurance company like Wellpoint.
