Best Dialysis Centers in California
110 of California's 737 dialysis centers hold the top CMS rating of 5 stars. The ranking below uses only the official CMS Quality of Patient Care star rating — measured outcomes like patient survival, hospitalizations, and readmissions. We add no editorial opinions.
Top-rated dialysis centers in California
Centers with the same star rating are listed alphabetically — CMS does not rank within a star level. 50 California centers have no current rating (often newer or low-volume facilities) and are excluded here but listed on city pages.
How to use this list: shortlist 2–3 highly rated centers near you, then call to confirm chair availability, shift
times, and insurance. Star ratings summarize past measured outcomes — they're a strong signal, not a guarantee.
