Medicare: U.S. Health Insurance Policy Overview
This paper examines Medicare, the federal social insurance program established in 1965 to provide health coverage to Americans aged 65 and older, as well as disabled individuals and those with end-stage renal disease. The paper traces Medicare's historical development, explains its four-part structure (Parts A, B, C, and D), describes financing mechanisms through payroll taxes and premiums, outlines eligibility requirements, and compares Medicare's cost efficiency to private insurance markets. Key topics include statutory benefit determination, risk pool management, and criticisms of the program's entitlement model.

- Provides concrete statistics (47 million beneficiaries in 2010, $182.7 billion in inpatient costs) that ground policy discussion in measurable outcomes.
- Traces policy evolution chronologically, showing how Medicare expanded from 1965 through 2013 to include new populations and services.
- Explains complex financing through layered detail: payroll tax rates, premium structures, income thresholds, and surtax changes.
- Clarifies the four-part program structure systematically, distinguishing Hospital Insurance (A), Medical Insurance (B), Prescription Drug (D), and Managed Care (C) alternatives.
Key academic technique demonstrated
The paper employs structured policy analysis: defining the program's scope, documenting historical milestones, systematizing financing mechanisms, establishing eligibility categories, and comparing performance against private insurance. This approach moves from foundational definition through operational complexity to evaluative critique, enabling readers to understand both how Medicare functions and why it matters in health care delivery.
Structure breakdown
The paper opens with a definitional overview anchored in establishment date and population served, then progresses through four middle sections that explain the policy machinery (history, financing, eligibility, structure), followed by a comparative section that positions Medicare against private markets. The final section addresses criticisms and summarizes the program's 40+ year trajectory. This architecture balances descriptive breadth with analytical depth, moving from policy architecture to critical evaluation.
Overview and Purpose of Medicare
Medicare in the United States was established in 1966 and is defined as a national social insurance program whose administration is vested in the federal government. The policy is dispensed through 30 private insurance organizations in the country. Medicare provides health insurance to Americans aged 65 years and older who have worked and paid into the national system (Nadeau, Belanger & Petry, 2014). The policy also provides health insurance benefits to younger people with amyotrophic lateral sclerosis, disabilities, and end-stage renal disease.
Medicare provided health insurance to close to 47 million residents in 2010. Of these, 40 million were aged 65 years and above, while 7 million were younger individuals with disabilities. The policy was the primary payment source for close to 15.4 million inpatient cases in 2011, accounting for $182.7 billion (47.2 percent) of aggregate inpatient costs in United States hospitals. Medicare was established to serve a larger population of disabled and elderly individuals. The average Medicare coverage represents close to 48.3 percent of all health care charges among enrolled individuals (Barr, 2011). Enrollees must cover the remainder of charges through supplemental insurance and alternative out-of-pocket coverage forms. Out-of-pocket charges vary according to the health care needs of a Medicare enrollee. The program does not cover hearing, dental, long-term care, and vision services, for which supplemental insurance is required (Nadeau, Belanger & Petry, 2014).
Historical Development and Policy Changes
In 1965, Medicare provisions expanded to include benefits for physical therapy, chiropractic therapy, and speech pathology. In 1972, Medicare introduced different payment options through health maintenance organizations, a structure that continued into the 1980s. In the 1990s, Congress expanded Medicare eligibility to include younger people with permanent disabilities who received Social Security Disability Insurance payments (Almgren, 2013). This category also includes people with end-stage renal diseases. Toward the end of the 1990s, the HMOs framework was formalized through President Clinton's health policy initiatives in 1997. In 2003, the Medicare program expanded to include prescription drug coverage, as authorized by President George W. Bush, with implementation beginning in 2006 (Nadeau, Belanger & Petry, 2014).
