Medicare is a federal health insurance program primarily for individuals aged 65 and older. However, it also covers certain younger individuals with disabilities or specific medical conditions. Medicare is divided into four parts, each serving different needs.

Part A: Hospital Insurance

Medicare Part A helps cover inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care. Most people do not pay a premium for Part A if they (or their spouse) have worked and paid Medicare taxes for at least 10 years.

Part B: Medical Insurance

Medicare Part B covers outpatient care, doctor visits, preventive services, and certain home health services. Part B requires a monthly premium, which varies based on income. It helps beneficiaries with medically necessary services and supplies.

Part C: Medicare Advantage

Part C, also known as Medicare Advantage, is an alternative to Original Medicare (Parts A and B). Offered by private insurance companies approved by Medicare, it includes all Part A and Part B benefits, and may also include additional coverage such as dental and vision. Many Medicare Advantage plans also include Part D for prescription drug coverage.

Part D: Prescription Drug Coverage

Medicare Part D provides prescription drug coverage to those enrolled in Medicare. This part is also offered through private insurers and is designed to help lower the cost of prescription medications. Beneficiaries can join a standalone Part D plan or get drug coverage through a Medicare Advantage plan that includes it.
