Kaiser Permanente’s Northern and Southern California health plans have been named the highest-quality commercial plans in the state by the California Center for Data Insights and Innovation.
The center rates commercial health plans using a rating system on a 1 to 5 star scale. The rating is based on 2024 data reported in 2025, derived from HEDIS measures (45 clinical indicators across 9 health topics) calculated by reviewing randomly sampled members’ medical charts and billing records against national care standards, with measures equally weighted and averaged into a summary score.
