CMS Nursing Home Health Deficiencies
The Centers for Medicare & Medicaid Services inspects every certified nursing home in the country. When inspectors find violations of federal quality standards, those citations are published as health deficiencies. Each deficiency is scored on a scope/severity grid from A (isolated, minimal harm potential) to L (widespread, immediate jeopardy).
This is 419,000+ deficiency citations from the CMS Provider Data Catalog, covering the three most recent inspection cycles. Search it. Filter it. See the patterns.
What do the severity codes mean?
Each deficiency gets a single letter A–L encoding two dimensions: severity (4 tiers) and scope (3 levels).
Severity tiers: Potential for minimal harm (A–C) → Potential for more than minimal harm (D–F) → Actual harm (G–I) → Immediate jeopardy (J–L).
Scope levels: Isolated (A, D, G, J) → Pattern (B, E, H, K) → Widespread (C, F, I, L).
Citations coded J, K, or L represent the most serious findings: immediate jeopardy to resident health or safety.
