## Content

ICER (Institute for Clinical and Economic Review) white paper released April 9, 2025, in collaboration with Brown University. Synthesizes literature and stakeholder interviews (PBMs, manufacturers, patient advocacy groups, benefit consultants, state/Medicaid experts).

**The cost reality for payers:**
- Self-insured employers offering GLP-1 obesity coverage saw **>10x increase in per-member, per-month (PMPM) costs** from January 2023 to December 2024
- Blue Cross Blue Shield of Massachusetts ended 2024 with a **$400 million operating loss**; GLP-1 drugs were "the single largest driver," accounting for **>$300 million in 2024**
- These numbers explain WHY California, NH, PA, SC eliminated Medi-Cal coverage — the cost trajectory is existential for plan solvency

**Strategies examined by ICER:**
1. Enhanced evidence-based coverage criteria (prior authorization, stricter eligibility)
2. Formulary and provider network management
3. Carve-out programs for obesity management services
4. Aggressive drug price negotiation in Medicare
5. Temporary coverage denial
6. Innovative payment arrangements (outcomes-based contracts)

**Key tension:**
ICER was criticized by the National Pharmaceutical Council for "prioritizing payers over patients" — the white paper addresses payer sustainability rather than patient access expansion. This reflects the structural tension: the drug works clinically but is fiscally unsustainable for the systems that would deliver it.

**PMC version (published peer-reviewed):**
A peer-reviewed version was published: "Affordable access to GLP-1 obesity medications: strategies to guide market action and policy solutions in the US" — PMC12403326 — extending the analysis.

## Agent Notes

**Why this matters:** The BCBS Massachusetts datum ($300M GLP-1 cost → $400M operating loss) is the single most concrete illustration of Belief 1's "compounding failure" at the payer level. It's not abstract — it's an insurer operating at a $400M loss because the drug that works for their members is bankrupting the plan. This is the mechanism by which clinical efficacy creates structural access rollback: payer solvency → coverage elimination → access loss.

**What surprised me:** The >10x PMPM increase in 2023-2024 (just two years) is steeper than I expected. California's $85M → $680M projection over 4 years is a ~8x increase. But employer plan costs went up >10x in just 2 years. This is a more acute cost curve than the state Medicaid trajectory suggests.

**What I expected but didn't find:** An ICER endorsement of expanded access. ICER is focused on payer sustainability strategies — the white paper is designed to help payers manage costs, not to argue for expanded coverage. This framing reflects the structural tension: even the most rigorous health economics organization is working on how to contain access, not expand it.

**KB connections:**
- The BCBS MA datum is the strongest payer-level evidence for the "continuous treatment = continuous cost = structural rollback" mechanism from Sessions 22-25
- Directly supports Belief 3 (structural misalignment): a drug that demonstrably reduces CV mortality (SELECT trial) is causing plan insolvency — the incentive structure cannot accommodate this
- The "coverage denial as strategy" and "prior authorization" framing connects to existing structural barrier claims
- Informs the California Medi-Cal story: California's $680M projection is consistent with what BCBS MA actually experienced in employer plans

**Extraction hints:**
- CLAIM: "GLP-1 obesity coverage is fiscally unsustainable for current payer structures: employer plans saw >10x PMPM cost increases in 2023-2024 and major insurers reported GLP-1s as their single largest operating loss driver"
- This is a concrete, specific, arguable claim backed by real numbers
- Could enrich the existing GLP-1 access/coverage elimination claims with the payer-side mechanism

**Context:** ICER is the most rigorous independent health technology assessment organization in the US. The NPC criticism ("prioritizes payers over patients") is itself informative — it reveals the structural tension between cost-effectiveness and access equity that underlies the entire GLP-1 coverage debate.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: GLP-1 access/coverage elimination claims + Belief 1 compounding failure mechanism
WHY ARCHIVED: Provides the payer-side financial mechanism for coverage elimination. The BCBS MA datum ($300M cost → $400M operating loss) makes the California decision rational from a plan solvency perspective — not ideological or negligent, but structurally forced.
EXTRACTION HINT: The extractable claim is about payer-level fiscal unsustainability. The BCBS MA numbers are the spine. This is NOT a general "access is hard" claim — it's specifically about the mechanism by which clinical efficacy creates financial unsustainability at the plan level.
