How we build this site

Where the data comes from

Everything comes from the nursing home datasets in the CMS Provider Data Catalog (data.cms.gov), which also feed Medicare's Care Compare: Provider Information, Health Deficiencies, Penalties, Survey Summary, Fire Safety Deficiencies, State and US Averages, and the Citation Code Look-up. The current files were processed by CMS on Sep 1, 2026; CMS lists the next update for Oct 28, 2026. We download the full public files each month, keep a dated copy, and rebuild the site.

The data covers nursing homes certified by Medicare or Medicaid. It does not cover assisted living or memory care communities that are licensed only by the state.

What we copy, and what we count

Inspection cycles and the star rating

CMS groups inspections into cycles: a standard inspection plus the complaint and infection-control inspections that go with it. Our counts cover the three most recent cycles in the data, the same window as the Health Deficiencies file. CMS's health inspection star rating uses a weighted score with different rules, so our counts and the stars will not always move together. We do not create our own rating.

"Immediate jeopardy" lists use CMS severity letters J, K and L. We separate citations from the 12 months before the data's processing date that are not recorded as past non-compliance, because past non-compliance means the home had already found and fixed the problem before inspectors arrived.
