Submit Patient-Level Administrative Data
About Us
To meet California’s needs in making informed decisions and through partnerships with healthcare facility data providers, HCAI has been collecting quality, timely, secure, and comprehensive inpatient discharges since 1983 — and emergency department and ambulatory surgery encounters, from both hospital-based ambulatory surgery centers and licensed freestanding ambulatory surgery clinics, since 2005. Data are submitted via HCAI’s secure data collection system.
2023 Patient Data Reporting Regulations Approved!
The Department of Health Care Access and Information (HCAI) is pleased to announce that the Patient Data Section’s regulatory proposal was accepted and approved by the Office of Administrative Law on July 18, 2022. The new regulations require full patient address reporting, including a housing status indicator, in addition to the currently required ZIP Code. Several other data elements were updated to align them more closely with national standards. These changes are in effect for Inpatient discharges and Emergency Department and Ambulatory Surgery encounters occurring on or after January 1, 2023.
