Patient Origin/Market Share (Pivot Profile)–Inpatient, Emergency Department, and Ambulatory Surgery

Published by Department of Health Care Access and Information | State of California | Catalog Last Checked: July 31, 2026 at 08:46 PM | Dataset Last Updated: October 08, 2025 at 05:19 PM
This dataset contains annual Excel pivot tables that identify where a facility’s patients come from (Patient Origin) and where patients from a specific area go to (Market Share) for hospital inpatient, emergency department, and ambulatory surgery treatment. The Patient Origin Report shows the ZIP codes of origin (based on a selected facility or facility county) and the Market Share Report lists the destination facilities (based on a selected patient ZIP code or patient county). Note: Physician-owned ambulatory surgery clinics do not report their data to HCAI and, therefore, are not included here.
