California home health care agencies: 3,147 Medicare-certified, source-cited quality data.

CMS Quality of Patient Care star rating, ownership type, and certification status for every Medicare-certified home health agency in California — with explicit suppression flags where CMS withholds quality measures because of low patient volume.

Editorial note: California has dense local journalism + AARP coverage of home-care services; Fonteum's contribution is the per-agency data layer, not editorial commentary.

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.

Integrated, with-data, and fresh-observation counts are separate. No platform-wide source-completeness count is published. Completeness is source-specific and must be evaluated against the named source's expected scope. State coverage is a separate jurisdiction measure.

Source authority is record-specific

Use the issuer named on the record.

Fonteum spans federal, state, and global public publishers. A source page or returned record identifies its issuer and dataset where that metadata is available. A platform registry count does not assign every page to one authority or establish loaded, fresh, or complete coverage.

Reproducible by design

Inspect the evidence each published figure actually supplies.

Source and date

Research pages expose the named public file and observation date where those fields are available. Source-file SHA-256 coverage is separate; facts do not currently link deterministically to signatures.

Available derivation

Studies with a retained release and committed derivation link the SQL or method used. Other studies state the evidence and reproduction limits they actually have.

Daily observations

Dated table row-count observations can detect local drift. They do not imply that an upstream publisher released or Fonteum ingested new data that day.
