# GLP-1 access structure is inverted relative to clinical need because populations with highest obesity prevalence and cardiometabolic risk face the highest barriers creating an equity paradox where the most effective cardiovascular intervention will disproportionately benefit already-advantaged populations

The Lancet frames the GLP-1 equity problem as structural policy failure, not market failure. Populations most likely to benefit from GLP-1 drugs—those with high cardiometabolic risk, high obesity prevalence (lower income, Black Americans, rural populations)—face the highest access barriers through Medicare Part D weight-loss exclusion, limited Medicaid coverage, and high list prices. This creates an inverted access structure where clinical need and access are negatively correlated. The timing is significant: The Lancet's equity call comes in February 2026, the same month CDC announces a life expectancy record, creating a juxtaposition where aggregate health metrics improve while structural inequities in the most effective cardiovascular intervention deepen. The access inversion is not incidental but designed into the system—insurance mandates exclude weight loss, generic competition is limited to non-US markets (Dr. Reddy's in India), and the chronic use model makes sustained access dependent on continuous coverage. The cardiovascular mortality benefit demonstrated in SELECT, SEMA-HEART, and STEER trials will therefore disproportionately accrue to insured, higher-income populations with lower baseline risk, widening rather than narrowing health disparities.

## Extending Evidence

**Source:** KFF Medicaid GLP-1 analysis, January 2026

Nearly 4 in 10 adults and a quarter of children with Medicaid have obesity, representing tens of millions of potentially eligible beneficiaries. Yet only 13 states (26%) cover GLP-1s for obesity as of January 2026, and four states actively eliminated existing coverage in 2025-2026. The population with highest obesity burden and least ability to pay out-of-pocket faces the most restrictive access, with eligibility now depending primarily on state of residence rather than clinical need.


## Supporting Evidence

**Source:** KFF Medicaid GLP-1 Coverage Analysis, January 2026

The Medicaid population has the highest obesity burden (40% of adults, 25% of children) but only 26% of state programs provide coverage. Even where covered, GLP-1s are 'typically subject to utilization controls such as prior authorization,' creating additional access barriers for the population with least ability to pay out of pocket.


## Extending Evidence

**Source:** KFF analysis of Medicare GLP-1 Bridge program (April 2026)

The Medicare GLP-1 Bridge program provides concrete evidence that the access inversion operates through federal program architecture, not just market dynamics. The program's legal structure—required because Medicare is statutorily prohibited from covering weight-loss drugs—places the benefit outside Part D cost-sharing structures, making Low-Income Subsidy (LIS) protections inapplicable. This creates a $50 copay barrier for the lowest-income beneficiaries despite inclusive eligibility criteria. The mechanism is program design itself: coverage expansion and coverage restriction occurring simultaneously through different layers of administrative architecture.


## Supporting Evidence

**Source:** KFF 2025 national poll, N=1,309 adults

KFF national poll finds only 23% of obese/overweight adults currently taking GLP-1s, meaning 77% of the eligible population is not accessing treatment despite drug availability. Among current users, 56% report difficulty affording medications, and 27% of insured users paid full cost out-of-pocket. Cost-driven discontinuation (14%) rivals side effect discontinuation (13%), demonstrating affordability as a primary access barrier.


## Extending Evidence

**Source:** ICER White Paper April 2025

ICER's white paper explicitly focuses on 'payer sustainability strategies' rather than access expansion, and was criticized by the National Pharmaceutical Council for 'prioritizing payers over patients.' This institutional framing reveals that even rigorous health economics organizations are working on how to contain access, not expand it, because the cost trajectory threatens plan solvency.


## Supporting Evidence

**Source:** ITIF August 2025, cross-referenced with ICER/KFF data

ITIF's 74 million eligible obesity treatment population figure provides the denominator for the 23% access rate documented in KFF polling. The contrast between ITIF's expansive potential framing (133M users, 0.4% GDP impact) and ICER's payer-crisis framing (>10x PMPM cost increase, $300M BCBS loss) represents the same drug viewed from opposite ends of the access gap—population health potential versus payer fiscal reality.


## Supporting Evidence

**Source:** WHO Global Guideline on GLP-1 Medicines for Obesity Treatment, December 2025

WHO explicitly states that current global access and affordability for GLP-1s are 'far below population needs' and that GLP-1s 'should be incorporated into universal health coverage and primary care benefit packages' but acknowledges this is not yet reality anywhere in the developing world. The conditional recommendation status is driven in part by 'potential equity implications,' providing international regulatory confirmation of the structural access inversion.


## Supporting Evidence

**Source:** ICER Final Evidence Report, December 2025

ICER report documents the access inversion at policy level: California Medi-Cal (serving lowest-income population) eliminated coverage January 2026 despite 14-0 clinical evidence. Medicare coverage restricted to cardiovascular risk indication, excluding pure obesity. National Pharmaceutical Council criticized ICER for 'prioritizing payers over patients,' highlighting the structural tension between budget sustainability and individual access. The 14-0 clinical verdict combined with simultaneous coverage elimination is the clearest expression of structural misalignment.


## Supporting Evidence

**Source:** on/healthcare.tech coverage expansion analysis

Coverage expansion data shows 43% of 5,000+ employee firms now cover GLP-1s for weight loss (up from 28% in 2024), while state mandates are emerging (North Dakota January 2025, California/Connecticut/West Virginia introducing legislation). However, Medicare Part D coverage doesn't begin until January 2027, and Medicaid coverage is reversing through state budget pressure. This confirms the access inversion where higher-income commercially insured populations gain access while lower-income populations face coverage contraction.
