Coding Definitions of Selected Ambulatory Surgical Procedures This Appendix lists the coding definitions for each of the 12 ambulatory surgical procedures of interest in this study. The ambulatory surgical procedures were defined using either International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) or Current Procedural Terminology (CPT-4) procedure codes, depending upon the coding system in each of the Agency for Healthcare Research and Quality (AHRQ) Healthcare Cost and Utilization Project (HCUP) State Ambulatory Surgery Databases (SASD). The surgery was not required to be the first-listed or principal procedure. A CPT procedure code indicating that the patient received anesthesia was not considered sufficient evidence that the patient had the procedure. A code indicating that the procedure was performed was required for inclusion. Cancer was defined by an ICD-9-CM diagnosis code (principal or secondary) on any discharge record in the year and was not required to be reported on the day of surgery. eTable 1.
