# GLP-1 behavioral support mandates tripled in one year (10% to 34%) signaling structural shift from drug-only formulary to managed-access operating systems

PHTI's December 2025 employer survey found that 34% of firms covering GLP-1s now require dietitian, case management, therapy, or lifestyle participation as a coverage condition, up from 10% the prior year—a 3.4x increase in 12 months. This is not incremental adoption but structural acceleration. Three major payers have operationalized this shift: Evernorth EncircleRx (9M lives, $200M saved since 2024), Optum Rx Weight Engage (coaching + specialist navigation), and UHC Total Weight Support (mandates Real Appeal Rx or WeightWatchers as coverage prerequisite). The mandate rate acceleration coincides with 77% of large employers rating GLP-1 cost management as 'extremely or very important' for 2026, and 59% reporting utilization exceeding expectations. The shift is driven by economic necessity: 36.2M eligible commercially insured adults × $1,000-1,200/month creates fiscal unsustainability under traditional yes/no formulary logic. Payers are building what PHTI calls 'managed-access operating systems' covering population qualification, channel routing, behavioral gates, subsidy levels, and discontinuation rules. This is infrastructure, not incremental policy adjustment.

The behavioral mandate acceleration (34% of employers requiring support, up from 10%) is occurring simultaneously with a 22% decline in total covered lives (3.6M to 2.8M), suggesting market bifurcation: large sophisticated employers add managed-access infrastructure while regional payers and mid-market employers drop coverage entirely. The two trends are compatible but create divergent access pathways.

**Source:** PHTI December 2025 Employer GLP-1 Approaches Report + Mercer 2026

PHTI December 2025 report confirms 34% of employers requiring behavioral support as GLP-1 coverage condition (up from 10% — 3.4x in one year). Critical scope qualification: this applies to LARGE employers (500+ employees or self-insured) who have already chosen to cover GLP-1s. Survey methodology covers employer-sponsored plans with sufficient scale to administer condition-based coverage. Mercer 2026 data shows 90% of large employers plan to continue GLP-1 coverage through 2026, 86% of mid-market employers continuing. The behavioral mandate represents cost management within continuing coverage, not coverage elimination.
