Parts A and B together make up what is known as Original Medicare. Medicare Part A is hospital insurance. It typically covers inpatient care in a hospital, nursing home care, home health care, hospice care, and skilled nursing facility care.
Medicare Part B is medical insurance. It typically covers services that are deemed medically necessary as well as preventive and screening services.
Also known as Medigap, Medicare Supplements are health insurance plans that help fill the gaps in Original Medicare coverage (Medicare Part A and Medicare Part B). It’s sold by private companies and can help pay for health care costs like deductibles, coinsurance, and copayments.
