California home health agencies — FAQ
- How many Medicare-certified home health agencies are in California?
- 3,147 Medicare-certified home health agencies operate in California as of the CMS Care Compare Home Health snapshot (2026-05-07). 1,947 carry a published CMS Quality of Patient Care star rating, averaging 3.16 of 5.
- What quality measures does California home health data include?
- This page aggregates the CMS Quality of Patient Care star rating — CMS's published composite of the underlying OASIS outcome and process measures — plus the share of agencies offering each service line. The individual OASIS measure rates and HHCAHPS patient-experience scores live in separate CMS companion files and are not part of this identity-and-rating snapshot.
- Why do some agencies have no star rating?
- CMS suppresses the Quality of Patient Care star rating when an agency has fewer than the minimum number of completed quality episodes in the measurement window. Those agencies still appear in the list but are excluded from the state average rather than counted as zero.
- Where does this home health data come from and how current is it?
- The displayed fields come from the CMS Care Compare Home Health Care Agencies file, source-modified 2026-03-05. Record-level provenance can be null; cross-check a consequential agency record at Medicare.gov.
