The free grade on this page contains zero zReports judgment: it maps the state's own published licensing and enforcement verdicts through one fixed rule, applied identically to every dialysis center in America. Where the record and public reputation diverge, a highly reviewed facility with serious findings on file, the paid Consumer Intelligence Report™ surfaces it through the composite Consumer Z Score™ and our published ten point methodology. Facilities are never contacted and cannot pay to change a score. Read the full methodology →
Dialysis Centers in California are overseen by the Centers for Medicare & Medicaid Services (CMS), whose certification, inspection, and quality-reporting data is published on the public record. This page is computed from CMS Dialysis Facility Compare data, the government’s own filings, not reviews or advertising.
California has 737 active licensed dialysis centers on the state's public file, across 278 cities, with a combined licensed capacity of 15,400. Every one has a free records layer grade on zReports.
Los Angeles, with 37 licensed dialysis centers, followed by Sacramento (21) and San Jose (19).
The free records layer grade contains zero zReports judgment. It maps the government's own published verdicts, CMS Dialysis Facility Compare data, through one fixed rule, applied identically to every dialysis center in the country. The paid Consumer Intelligence Report™ adds the composite Consumer Z Score™, which audits the record against public reputation through our published ten point methodology.
Reviews and records are different surfaces. Reviews reflect what visitors chose to write, and can be managed by the business. Inspection and enforcement records are filed by the state, are mandatory, and cannot be edited by the facility. When the two diverge, the record is the surface worth checking. That divergence is exactly what zReports was built to surface.
Rankings refresh whenever California republishes its licensing data; facility pages carry the records-verified date for each provider. This page was generated from the current file as of October 2026.
No. Facilities are never contacted, never notified, and cannot pay to be listed, delisted, or re-scored. zReports has no business relationship with any facility it grades, independence is the product.
This report was generated from the zReports Consumer Records Database™, a continuously updated database that normalizes official government licensing, inspection, enforcement, ownership, and safety records across multiple federal and state agencies. Every statistic in this report is traceable to its originating public record. Facilities cannot pay to alter scores, rankings, or findings.
