What is Medicare?
Medicare is a federal health insurance program primarily for individuals who are 65 years or older, as well as for some younger individuals with disabilities and people with end-stage renal disease. It is divided into parts, each covering different healthcare needs.
Medicare offers different parts: Part A, Part B, Part C (also known as Medicare Advantage), and Part D. These cover different healthcare needs like hospital insurance, medical insurance, prescription drug coverage, and more.
Medicare spending is funded through various sources, including general federal revenues, payroll taxes from employees and employers, premiums paid by Medicare beneficiaries, taxes on Social Security benefits, interest earned on trust fund investments, funds authorized by Congress, and payments from states.
These funds are allocated to different parts of Medicare, such as Part A, Part B, and Part D, each with its specific financing structure. The Centers for Medicare and Medicaid Services (CMS) administers the program, while the Social Security Administration handles enrollment.
