Federal inspection record
Immediate-jeopardy citations (CMS scope/severity J–L) are the most serious category federal inspectors issue — meaning a deficiency placed residents in immediate risk of serious harm. Ask the facility for the corrective-action plan filed with CMS, and consider contacting your state long-term care ombudsman for context.
