Medicare Care Compare

Safely compare two to five hospitals for one exact CMS Timely and Effective Care measure and one exact reporting period. No comparison is returned when a facility is missing data or CMS rows are incompatible.

Find current official CMS home-health agencies by public agency name, CCN, or agency office geography, returning current quality-of-care stars, the latest HHCAHPS patient-survey stars, reporting periods, release dates, and source links. Geography identifies an office location, not a verified patient service area; never claim service coverage from this result.

Find current Medicare-participating hospitals by public name or geography. Use this first to resolve a hospital name or location into a CMS facility ID.

Find current official CMS nursing homes by public facility name, CCN, or geography, returning overall, health-inspection, staffing, and quality-measure star ratings with source links and release dates.

Retrieve current CMS details for one hospital facility ID returned by find_hospitals.

Retrieve or safely compare official CMS hospital outcomes. Choose complications/mortality, unplanned visits/readmissions, or healthcare-associated infections. Multi-hospital comparisons require one exact measure and reporting period and fail closed for missing or suppressed data.

Retrieve or safely compare official CMS HCAHPS patient-experience measures, including stars, answer percentages, survey counts, response rates, reporting periods, and CMS footnotes.

Retrieve dated CMS Timely and Effective Care measures for one hospital. Optionally narrow to one CMS measure ID and one exact reporting period.

The response states whether that measure has a supported official-source provider. When no period is supplied, return definitions only for represented dataset periods. Summarize each returned numerator and thresholds and show official_url.
