The United States health care industry stands as one of the largest and most complex sectors in the global economy, reflecting substantial financial investment and ongoing growth over recent decades. As of recent estimates, total national health expenditures in the U.S. surpassed $4.9 trillion in 2023, accounting for approximately 18.3% of the gross domestic product (GDP). This fiscal magnitude underscores the critical importance of health care in economic planning and policy development. The growth in health care expenditures has been driven by multiple factors, including technological advancements, an aging population, increased prevalence of chronic diseases, and administrative costs. Historically, health expenditures have escalated at a rate exceeding general inflation, emphasizing the need for sustainable financing strategies (National Health Expenditure Data, 2023).

The U.S. health insurance landscape is characterized by three primary categories: voluntary health insurance, social health insurance, and welfare medicine. Voluntary health insurance operates predominantly through employer-sponsored plans and individual policies purchased by consumers. It accounts for a significant share of coverage but is often tied to employment status, which can lead to gaps in coverage during unemployment or among self-employed individuals (Kaiser Family Foundation, 2022). Social health insurance, although less prevalent in the U.S. compared to other countries, involves government-mandated schemes like Medicare and Medicaid that provide coverage to specific populations, such as seniors or low-income families. Welfare medicine encompasses government-funded programs that seek to promote health equity and access for vulnerable populations, primarily through Medicaid and other social safety-net initiatives.

Medicare, the federal health insurance program primarily serving individuals aged 65 and older, consists of four parts. Medicare Part A covers hospital insurance, including inpatient stays and skilled nursing facilities, funded mainly through payroll taxes. Part B provides outpatient services, physician visits, and preventive care, financed through premiums and general revenues. Medicare Part C, known as Medicare Advantage, offers managed care plans that provide Part A and B benefits through private insurers, often with additional benefits. Part D delivers prescription drug coverage, purchased via private plans that receive government subsidies (Kaiser Family Foundation, 2023).

The Medicaid program is a joint federal and state initiative designed to assist low-income individuals and families in accessing necessary health care services. Its scope and eligibility criteria vary significantly across states, but it generally covers services such as hospital care, physician visits, mental health, and long-term care. Medicaid is financed through federal and state contributions, with the federal government matching state expenditures based on per capita income levels. The program plays a vital role in reducing health disparities among socioeconomically disadvantaged groups.

Physician reimbursement methods in the U.S. include a variety of approaches, with fee-for-service (FFS) being the most traditional. Under FFS, physicians are compensated based on the volume and complexity of services provided, which can incentivize higher service rates but may also lead to unnecessary procedures. Alternative approaches like capitation pay physicians a set amount per patient regardless of services rendered, encouraging cost-effective care. The introduction of pay-for-performance models ties reimbursement to quality metrics, aiming to improve health outcomes and accountability. These methods reflect ongoing efforts to balance cost containment with quality care provision (Centers for Medicare & Medicaid Services, 2022).

The prospective payment system (PPS) represents a significant shift in hospital reimbursement, where payments are predetermined based on diagnoses, procedures, and patient characteristics, rather than actual charges. Implemented initially for Medicare inpatient hospital services under the Diagnosis-Related Group (DRG) system, PPS incentivizes hospitals to contain costs while maintaining quality. This model aims to promote efficiency by aligning hospital incentives with cost-effective care practices, reducing unnecessary expenditures, and simplifying reimbursement procedures (Medicare Payment Advisory Commission, 2021).
