Healthcare Cost and Utilization ProjectThe Healthcare Cost and Utilization Project (HCUP, pronounced "H-Cup") is a family of databases, software tools and related products developed through a Federal-State-Industry partnership and sponsored by AHRQ. HCUP databases are derived from administrative data and contain encounter-level, clinical and nonclinical information including all-listed diagnoses and procedures, discharge status, patient demographics, and charges for all patients, regardless of payer (e.g., Medicare, Medicaid, private insurance, uninsured), beginning in 1988.
