Analyst Notes
This projection model for Washington employers uses composite rate data derived from CMS Medical Loss Ratio (MLR) filings and MEPS-IC survey results. The fully insured baseline reflects Washington-specific community rating adjustments where applicable, while self-funded projections incorporate stop-loss premium estimates from the Self-Insurance Institute of America (SIIA) benchmarking data. PEO rates are modeled using aggregated large-group purchasing power discounts typically ranging from 8-22% depending on industry classification and claims history.
Rate trend assumptions for Washington are based on a blended index of KFF Employer Health Benefits Survey data, Milliman Medical Index growth rates, and state-specific regulatory filings. The captive insurance projections assume a minimum of 50 participants in a group captive structure with appropriate reinsurance attachment points. Employers with favorable loss ratios (under 65%) may see additional savings not fully captured in these directional estimates.
