About 0WHC3GZ

0WHC3GZ is the ICD-10-PCS code for a insertion procedure on the mediastinum using a percutaneous 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 0WHC0GZ (open) and 0WHC4GZ (percutaneous endoscopic).

With a different device, use 0WHC31Z (radioactive element), 0WHC33Z (infusion device) and 0WHC3YZ (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.
