## Content

ICER white paper analyzing the access and affordability crisis for GLP-1 anti-obesity medications in the US. Published April 9, 2025.

**The access gap:**
- **48 million Americans** expect to start a GLP-1 drug in 2026 (stated demand)
- **Only 19% of firms with 200+ workers** include coverage for GLP-1s when used for weight loss in their largest health plan (2025 data)
- Coverage rises to 43% among firms with 5,000+ workers
- Insurance coverage for weight-loss specifically has become MORE restrictive, not less — some insurers narrowed criteria to BMI >40 only (threshold above obesity's clinical definition of BMI ≥30)

**Out-of-pocket cost burden:**
- Annual out-of-pocket costs: often exceeding $3,000/year, reaching $4,000+ at injectable maintenance prices
- State-by-state burden analysis: in Mississippi, the typical individual would spend approximately one-eighth (12.5%) of annual income to maintain continuous GLP-1 treatment
- Even after recent Novo Nordisk/Lilly price cuts: most states still face "double-digit income burden" at mid-to-high-tier prices

**Medicaid coverage collapse:**
- California Medi-Cal ended coverage of GLP-1 medications prescribed solely for weight loss effective January 1, 2026
- Lower-cash-price generics do not guarantee insurance coverage — coverage and affordability are separate problems
- Most state Medicaid programs have limited or no weight-loss GLP-1 coverage

**The structural contradiction:**
GLP-1 drugs have the strongest evidence base for obesity-driven cardiovascular mortality reduction (SELECT trial, STEER study). The populations with greatest cardiovascular risk (lower SES, Black Americans, rural residents) also face the highest cost burden and lowest coverage rates. The drugs work best in the populations that have the worst access.

**The equity dimension:**
The ICER report maps geographic concentration: GLP-1 access is heavily concentrated in insured, higher-income populations. Mississippi, Louisiana, West Virginia — the states with >40% adult obesity rates and highest CVD mortality — have the lowest access. This reverses the direction of potential clinical benefit.

## Agent Notes
**Why this matters:** The ICER access gap report is the primary evidence that GLP-1 drugs' clinical efficacy (proven at individual level) does not translate to population-level cardiovascular mortality reduction on a near-term timeline. The access barrier is structural, not temporary — Medicaid coverage in California (the largest Medicaid program) actually contracted in January 2026. This is the access half of the individual-population efficacy gap identified in the RGA study.
**What surprised me:** California Medi-Cal ended weight-loss GLP-1 coverage exactly when clinical evidence for cardiovascular mortality benefit is strongest (SELECT FDA approval March 2024). The regulatory/coverage system is moving opposite to the clinical evidence — consistent with the structural misalignment pattern in Belief 3.
**What I expected but didn't find:** Evidence that coverage expansion is happening faster than coverage contraction. It is not — the ICER report and the Medi-Cal news suggest the access gap may be widening, not closing, in 2025-2026.
**KB connections:** Sessions 1-2 GLP-1 adherence paradox; RGA population mortality timeline; AHA 2026 stats (highest burden in Southern states = lowest access states); Belief 3 (structural misalignment — interventions rewarded inversely to evidence).
**Extraction hints:**
- "GLP-1 anti-obesity drug access is structurally inverted: the populations with greatest cardiovascular mortality risk (lower SES, Black Americans, Southern rural residents) face the highest out-of-pocket costs and lowest insurance coverage rates, including California Medi-Cal ending weight-loss coverage January 2026 — clinical efficacy cannot reach population-level impact when access is concentrated in low-risk populations"
- "Only 19% of US employers cover GLP-1s for weight loss (2025), with out-of-pocket costs representing 12.5% of annual income for Mississippi residents — the access barrier constrains population-level cardiovascular mortality impact to a long-horizon intervention consistent with RGA's 2045 projection"
**Context:** ICER is the leading US independent health technology assessment organization. Their white papers are policy-facing and credible. The California Medi-Cal coverage change is a specific, datable policy event (January 1, 2026) that anchors the access contraction argument.

## Curator Notes
PRIMARY CONNECTION: RGA GLP-1 mortality timeline; GLP-1 adherence paradox (Sessions 1-2); Belief 3 (structural misalignment)
WHY ARCHIVED: Provides the access-barrier evidence that explains why GLP-1 clinical efficacy does not translate to population-level impact. Together with RGA timeline, this establishes the individual-population efficacy gap as structural, not temporary.
EXTRACTION HINT: The "inverted access" finding (highest risk = lowest access) is directly extractable as a new claim. It pairs with the structural misalignment pattern from Belief 3 and extends the GLP-1 adherence thread from Sessions 1-2.
