About 0WHC0GZ
0WHC0GZ is the ICD-10-PCS code for a insertion procedure on the mediastinum using an open approach with defibrillator lead. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.
The same procedure with a different approach is coded 0WHC3GZ (percutaneous) and 0WHC4GZ (percutaneous endoscopic).
With a different device, use 0WHC01Z (radioactive element), 0WHC03Z (infusion device) and 0WHC0YZ (other device).
It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC), DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), DRG 265 (AICD Lead Procedures) and DRG 275 (Cardiac Defibrillator Implant with Cardiac Catheterization and MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “AICD Lead Procedures” and “Cardiac Defibrillator Implant with Cardiac Catheterization”.
It was added in FY2024, effective October 1, 2023.
