Across the 667 Medicare-certified nursing homes in Illinois, the average facility carries 26.9 total health-inspection deficiencies on its most recent CMS standard survey, compared with a national average of 9.2. A "deficiency" is a specific F-tag citation written by state surveyors during the annual federal inspection under 42 CFR §483, each citation maps to a scope-and-severity grid (A through L) that determines whether it is an isolated low-harm issue or a widespread immediate-jeopardy finding. The Illinois state-level average reflects the sum of all F-tag citations divided by the number of facilities; it does not distinguish between low-severity paperwork findings and high-severity resident-harm citations, which is why drilling into any facility's full survey report matters more than the headline count. This page uses 14,693 Medicare-certified nursing-home records from CMS Care Compare, with NPPES context where available. Every figure is traceable in the methodology.

The table below ranks up to the top 100 Illinois facilities by total deficiency count (highest first) - the goal is transparency, not a blacklist. Facilities appear with their deficiency total, complaint-based deficiencies (citations triggered by a formal complaint rather than the routine survey), fine dollar amounts, and CMS Health Inspection component rating. A high count can reflect a facility with genuine quality problems, a more aggressive state survey team, a larger bed count with more opportunities for citation, or a complaint spike in a single cycle, context matters. Conversely, a low count does not guarantee good care; facilities rarely surveyed, or recently surveyed with a favorable cycle, can look clean while problems accumulate between inspections. The state's benchmark of 26.9 deficiencies and the national benchmark of 9.2 (average score 82) are starting reference points.

Deficiencies are based on CMS Rating Cycle 1 (the most recent completed standard survey); prior cycles appear on each facility's detail page. Important: PlainDoctor presents CMS deficiency data exactly as published at data.cms.gov - we do not aggregate, re-rank, or editorialize. This table is a research tool, not medical advice, a consumer rating, or a legal conclusion about any facility. Selecting a nursing home for yourself or a loved one should include in-person visits, reading the underlying F-tag narratives in the full CMS-2567 survey reports, interviewing staff and current residents' families, and consulting licensed clinicians, hospital discharge planners, and elder-law advisors familiar with Illinois long-term care regulations.
