The US Medicaid Program: Coverage, Financing, Reforms, and Implications for Health Equity.

Area of Science:

• Health Policy
• Health Equity
• Public Health Insurance

Background:

• Medicaid is the largest US health insurance program, covering diverse low-income populations.
• It plays a vital role in financing healthcare and addressing health disparities.
• The program faces challenges balancing its equity goals with fiscal and political pressures.

Purpose of the Study:

• To describe Medicaid's eligibility, enrollment, and spending.
• To examine key policy areas: managed care, payment, delivery system reforms, Medicaid expansion, and racial/ethnic health disparities.
• To assess opportunities for advancing health equity within Medicaid.

Main Methods:

• Analysis of publicly available data (2010-2022) on Medicaid enrollment and expenditures.
• Literature search of PubMed and reports from nonprofit/government organizations (2003-2022).
• Review of evidence on managed care, delivery reforms, expansion, and health disparities.

Main Results:

• Medicaid covered 80.6 million in 2022, representing 24.2% of the US population.
• It accounted for $671.2 billion in health spending (2020) and significant state/federal expenditures.
• While 38 states expanded Medicaid, disparities persist, with 56.4% of beneficiaries from minority groups facing access/quality inequities.

Conclusions:

• Medicaid's structure, financing, and reach have evolved through reforms and expansion.
• Significant policy reforms are essential to mitigate racial and ethnic health disparities.
• Focusing on equity in managed care and delivery reforms can advance health equity within Medicaid.
