Health inspections

Federal rules call for a standard inspection at least every 15 months, plus a visit whenever a complaint is filed. Each mark below is one citation, colored by how serious inspectors rated it. How to read a citation.

Under each citation, the quoted text is the inspector's own summary from the federal statement of deficiencies (CMS form 2567), word for word apart from a privacy scrub; CMS removes residents' and staff names before it publishes the text. The full notes are on Medicare.gov.
