# GLP-1 obesity coverage creates acute payer fiscal crisis with employer plans experiencing >10x PMPM cost increases in 2023-2024 and major insurers reporting operating losses driven primarily by GLP-1 expenditures

ICER's April 2025 white paper documents that self-insured employers offering GLP-1 obesity coverage experienced >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, with GLP-1 drugs identified as 'the single largest driver,' accounting for >$300 million in 2024 alone. This is a more acute cost curve than California's Medi-Cal trajectory ($85M → $680M projected over 4 years, ~8x increase), suggesting employer plan costs are escalating faster than state Medicaid programs. The BCBS MA datum provides the concrete mechanism for why states like California, New Hampshire, Pennsylvania, and South Carolina eliminated Medi-Cal coverage: the cost trajectory threatens plan solvency. This is not ideological opposition or negligent policy—it's structurally forced by fiscal reality. ICER's focus on 'payer sustainability strategies' rather than access expansion reflects the structural tension: even the most rigorous health economics organization is working on how to contain access, not expand it. The National Pharmaceutical Council criticized ICER for 'prioritizing payers over patients,' which itself reveals the zero-sum nature of the access-sustainability trade-off under current financing structures.


## Extending Evidence

**Source:** PHTI Employer GLP-1 Coverage Market Trend Report, December 2025

Employer response to GLP-1 cost pressure includes cost management strategies: step therapy, prior authorization, and lifestyle program requirements as coverage conditions. PHTI documents employers adopting 'scalable tech-enabled care with measurable outcomes' as the winning strategy in a 'high-pressure environment.' This shows payers are not simply cutting coverage but restructuring it around adherence and outcomes infrastructure to manage the fiscal burden.


## Extending Evidence

**Source:** on/healthcare.tech, Evernorth EncircleRx operational data

Evernorth EncircleRx reports ~$200 million saved since 2024 across 9 million enrolled lives through 15% cost cap or 3:1 savings guarantee structure. This represents early evidence that managed-access infrastructure can contain costs, though the $200M savings across 9M lives (~$22/member) is modest relative to the 10x PMPM increase that created the fiscal pressure.
