Frequently asked questions

What is the CMS overall star rating for Asem?
CMS has not published an overall star rating for Asem in the current Care Compare snapshot. A rating is assigned only when a hospital reports enough measures across the five CMS measure groups to be scored, so smaller or specialty facilities are often unrated.
Who owns Asem?
Asem is classified by CMS as "Government - State". Ownership type is reported by the hospital to CMS and published in the Hospital General Information dataset; it describes the controlling entity, not the quality of care, which Fonteum reports separately and traces to each source row.
How many CMS quality measures does Fonteum track for Asem?
Fonteum publishes 34 CMS quality measures for Asem across 1 groups — healthcare-associated infections. Every measure is a separate provenance claim signed to the CMS dataset, reporting period, and source row it was asserted from, and is hover-traceable on this page.
Where does Asem's quality data come from?
Asem's data is drawn directly from 2 primary CMS Care Compare datasets published on data.cms.gov, including patient survey, mortality, readmission, complication, infection, and timely-care files. Fonteum re-publishes each value with a chained 14-field provenance record rather than an aggregated score.
What does CMS Certification Number 400127 identify?
The CMS Certification Number (CCN) 400127 is the federal identifier Medicare assigns to Asem. It is unique, dated, and federally issued, and it links this hospital across every CMS dataset — cost reports, Care Compare quality files, and the Provider of Services file — which is how Fonteum joins Asem's records.
Does Asem provide emergency services?
Yes. CMS records that Asem provides emergency services, per the Hospital General Information dataset as of Q2 2026. Emergency-service status indicates the hospital operates an emergency department; it is reported by the hospital to CMS and chained to its source row on this page.
