7,557 Medicare-certified dialysis facilities — 5-star quality data, ownership transparency, and the documented chain-concentration story.
CMS-published 5-star ratings, profit-vs-nonprofit status, chain affiliation, and service offerings (in-center hemodialysis, peritoneal, home hemodialysis training) for every ESRD facility in the country, with explicit suppression flags for fewer-than-11-patient measure windows.
See the Audit Pack →90.2% of dialysis facilities are chain-owned in the current snapshot — concentrated under DaVita, Fresenius, and a handful of regional chains. 7,072 carry a CMS-published 5-star rating (mean 2.87 ★); the remaining 485 carry no public rating because of low patient volume in the measure window.
