Data insights
Quality ratings
Rossmoor Post Acute holds a CMS overall quality rating of 5 out of 5 stars, based on the most recent Care Compare release (data as of April 2026). CMS breaks this into three sub-ratings: health inspection (5/5), staffing (3/5), and quality measures (5/5).
What each sub-rating measures

The facility is classified under for profit - limited liability company ownership, a designation that can influence staffing patterns, reinvestment decisions, and admissions policy. At roughly 95% occupancy, this facility is running near full capacity, worth confirming current bed availability directly before visiting.
Same-ownership peers

Cost figures are monthly medians, refreshed annually with each new CareScout release; quality ratings are refreshed quarterly from the CMS Provider Information File. Read these state and county medians as benchmarks, then verify current rates with individual providers and consult care managers before making placement decisions.
