Values and averages are published by CMS (July 2026 release); "—" means CMS publishes no average for that measure. Where CMS assigns a risk-adjusted category ("Better than", "As" or "Worse than Expected"), that category is shown — we never rank those measures ourselves. For the other measures, "Better than X%" is computed by DialysisCompare: the share of New York facilities with at least 25 patients in the measure that this center does better than; centers with fewer patients are not ranked. One measure never tells the whole story — how every figure is sourced and computed.
Questions to ask this center
