BRIDGING THE MISSING MIDDLE: AN ADAPTIVE UNIVERSAL COVERAGE FRAMEWORK FOR ADVANCING HEALTH EQUITY AND CONTINUOUS ACCESS TO CARE: EVIDENCE FROM INDIA AND LESSONS FROM MEDICARE, MEDICAID, AND THE AFFORDABLE CARE ACT

Abstract

Background: India's Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (PM-JAY), the world's largest publicly financed health insurance program, has extended catastrophic-expenditure protection to over 500 million people. Yet a vast population of 300–400 million informal-sector workers, gig-economy labourers, and lower-middle-income households remains stranded between the poor covered by PM-JAY and the affluent insured through private markets. This structural exclusion, commonly termed the 'missing middle,' exposes a critical blind spot in India's architecture for Universal Health Coverage (UHC). Objective: This paper develops a theoretically grounded, comparative health policy framework to explain the structural persistence of the missing middle and to derive actionable design lessons from four major United States financing models, Medicare, Medicaid, the Affordable Care Act (ACA) marketplaces, and regulated private insurance, for a sustainable, equitable, and administratively feasible Indian health financing architecture. It also argues that the central limitation of PM-JAY is not simply incomplete insurance coverage, but the persistence of outpatient exclusion as a mechanism of stratified access, delayed treatment, and uneven therapeutic security across class, geography, and social position Methods: I employ a multi-layered comparative institutional analysis, integrating strategic purchasing theory, principal–agent frameworks, health economics, and equity frameworks (Andersen Behavioural Model; horizontal and vertical equity). Secondary data from official government sources, peer-reviewed literature, regulatory publications, and international organizations are triangulated across six analytical dimensions: target population, benefit design, financing, delivery model, financial protection outcomes, and system weaknesses. Findings: The missing middle persists because of the interaction of five structural forces: 1. labour market informality rendering contributory mechanisms infeasible; 2. the complete absence of an income-linked subsidy architecture; 3. fragmented risk pools driving adverse selection; 4. the exclusion of outpatient and pharmaceutical coverage from all public schemes, which accounts for ~60% of out-of-pocket expenditure; and 5. weak consumer protection and federal-state fiscal misalignment. A 2024 BMC Health Services Research study (Garg et al.) confirms that despite scale, PM-JAY has not measurably improved utilisation, quality, or financial protection after four years. The ACA reduced the US uninsured rate to a historic low of 7.7% by 2023, with 44 million enrolled in ACA-linked programmes by 2024. Medicaid expansion reduced racial disparities in infant and cardiovascular mortality. Medicare's prospective payment system introduced efficiency-aligned incentives that PM-JAY's administrative package-rate system conspicuously lacks. Proposed Framework: I introduce the Multi-Tiered Universal Health Coverage Architecture (MT-UHCA) for India, comprising four interlocking tiers: a tax-funded entitlement for the poor and elderly (anchored in PM-JAY); a subsidised 'Ayushman Marketplace' for the missing middle; regulated private insurance integrated through the National Health Claims Exchange (NHCX); and a cross-cutting outpatient and pharmaceutical benefit. The framework is operationalised through India's Ayushman Bharat Digital Mission (ABDM), which by 2026 has created over 90 crore ABHA health IDs, providing the digital public infrastructure to enable portability, risk adjustment, fraud control, and efficient subsidy delivery. Conclusions: Bridging the missing middle is simultaneously a moral imperative and a prerequisite for India achieving UHC. No single financing instrument,whether tax-funded, contributory, or market-based,can resolve this structural challenge in isolation. A hybrid model combining public financing, regulated private markets, income-linked subsidies, outpatient coverage, and digital infrastructure offers the most feasible pathway. This paper contributes a replicable conceptual and policy framework for other lower-middle-income countries grappling with analogous coverage-gap challenges. It also reframes outpatient exclusion as a health equity problem rather than a narrow issue of benefit incompleteness. It explains why insurance expansion does not automatically translate into equitable access when the most frequently used services remain outside effective protection. It develops a comparative access-centered argument showing that the most relevant international lessons for India concern benefit comprehensiveness, continuity of care, consumer protection, portability, and protection against underinsurance rather than payment architecture alone This paper argues that scale and financial protection are not synonymous. Despite covering over 500 million people, a 2024 peer-reviewed study found that PM-JAY has not significantly improved healthcare utilisation or financial protection. The paper identifies PM-JAY's principal limitation as the exclusion of outpatient and pharmaceutical services, which account for nearly 60% of household health expenditure. It therefore reframes the policy challenge from expanding enrolment to redesigning insurance benefits, offering a more realistic assessment of what the world's largest publicly funded health insurance programme has achieved and what reforms are needed.
