CMS Star Ratings

Overall rating
★★★★★
CMS’s composite of the three ratings below. California average: 3.2 stars.
Health inspection
★★★★☆
Based on the last three years of on-site inspections and complaint investigations — the rating CMS weights most heavily.
Staffing
★★★★★
Nurse and aide hours per resident per day, adjusted for how much care residents need, plus staff turnover.
Quality measures
★★★☆☆
Clinical outcomes CMS tracks, such as falls with injury, pressure ulcers and hospital readmissions.
The Tamalpais holds a 5-star overall rating, in the top tier CMS assigns. Its health-inspection rating is lower than its overall rating — the overall score is being lifted by staffing or quality-measure ratings, which draw partly on facility-reported data. None of this tells you whether a bed is open, whether your insurance is in network, or whether the facility will accept a given level of care — confirm those three directly with the facility before you commit.
