Medicare is a federal health insurance program in the United States primarily designed for individuals aged 65 and older, though it also provides coverage to certain younger individuals with disabilities or specific medical conditions, such as end-stage renal disease (ESRD). Medicare offers essential healthcare services, promoting access to affordable care for millions of Americans.

Medicare is divided into four parts:

• Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services.

• Part B covers outpatient care, preventive services, doctor visits, and medical supplies.

• Part C (Medicare Advantage) offers an alternative to Original Medicare by bundling Parts A and B, often with additional benefits like dental, vision, and prescription drug coverage.

• Part D provides prescription medication coverage to help reduce medication costs.

Medicare is funded through payroll taxes, premiums, and federal funding. Beneficiaries typically pay premiums, deductibles, and copayments based on their chosen plan.

This program ensures healthcare access and financial protection for seniors and qualifying individuals, supporting long-term health and financial stability during retirement and beyond.
