Summary & Overview
HCPCS G8913: Patient Confirmed No Wrong-Site/Procedure/Implant Event
HCPCS Level II code G8913 documents that a patient was confirmed not to have experienced a wrong site, wrong side, wrong patient, wrong procedure, or wrong implant event. Nationally, standardized use of this code supports procedural safety reporting, quality measurement, and administrative records that a safety check was completed and no adverse “wrong” event occurred. The code is relevant across hospital inpatient and outpatient surgical settings, ambulatory surgical centers, and procedure suites.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what G8913 represents, where it is typically used, and why it matters for clinical documentation and quality programs. The publication covers expected use cases, common modifiers and coding context, and practical considerations for aligning documentation with payer requirements. It also outlines how G8913 fits into broader safety and reporting workflows and what benchmarks and policy updates to monitor for national program alignment.

Clinical & Coding Specifications
Clinical Context
A 62-year-old male is scheduled for an elective left total knee arthroplasty at an ambulatory surgical center. Preoperative time-out, site marking, and informed consent are completed. Immediately prior to incision the surgical team documents that a wrong site, wrong side, wrong patient, wrong procedure, and wrong implant event did not occur; this documentation is entered into the operative record and billing record to support use of the HCPCS Level II code G8913. Typical workflow includes preoperative verification by nursing and anesthesia, time-out led by the surgeon in the operating room, confirmation of implant and laterality, and postoperative documentation in the operative note and the anesthesia record. The service is typically reported by the facility (hospital outpatient department or ambulatory surgery center) to indicate that the safety check was completed and no wrong-site/side/patient/procedure/implant event occurred.
