What is Medicare?
Medicare is a federal health insurance program run by the federal government. It is intended to provide health coverage to people aged 65 and up and younger people with specified disabilities.
As one of the primary health insurance programs in the United States, Medicare covers various medical services, including prescription drug coverage, from hospital to medical insurance. Enrollees may pay monthly premiums to access Medicare Advantage plans, a form of health insurance that bundles the standard benefits with additional services.
Medicare parts
Medicare is divided into numerous segments, each controlled by a federal organization named the Centers for Medicare & Medicaid Services (CMS). Each targets a particular set of healthcare requirements and is partially funded by federal grants with cost-sharing provisions.
- Part A (hospital insurance): Covers inpatient hospital care, skilled nursing facility care, hospice, and some home health care. This core covering is critical for major medical events and illnesses.
- Part B (medical insurance): Provides coverage for doctor's services, outpatient care, medical supplies, and preventive services. This part requires a monthly premium and includes cost-sharing for services like physical therapy and durable medical equipment.
- Part C (medicare advantage): These plans, offered by private companies approved by Medicare, include all of the benefits of Parts A and B as well as many extra services, such as dental care, vision, and hearing aids, tailored to the participants' health and needs.
- Part D (prescription drug coverage): Helps cover prescription medications, including numerous required immunizations or vaccines. Medicare-approved private companies offer Part D coverage.
- Medicare supplement insurance (Medigap): Private firms sell this insurance, which helps pay for some of the healthcare costs that Original Medicare does not cover, such as copayments, coinsurance, and deductibles.
This arrangement enables Medicare to act as the major payer for many health services, ensuring all beneficiaries have access to critical medical care at predictable out-of-pocket expenses.
