Ambulatory Surgery - Diagnosis and External Cause Codes

Published by Department of Health Care Access and Information | State of California | Catalog Last Checked: October 24, 2026 at 08:45 PM | Dataset Last Updated: September 18, 2026 at 12:40 AM
This dataset contains statewide counts for every diagnosis, procedure, and external cause of injury/morbidity code reported on the ambulatory surgery data. Diagnosis codes are reported using ICD-9-CM or ICD-10-CM. External cause of injury/morbidity codes are reported using ICD-9-CM or ICD-10-CM. ICD-10 replaced ICD-9, effective October 1, 2015. Note: Physician-owned ambulatory surgery clinics do not report their data to HCAI and, therefore, are not included in the statewide frequencies.
