02HM3MZ ICD-10-PCS Code: Insertion of Cardiac Lead into Ventricular Septum, Percutaneous Approach (2027)

About 02HM3MZ

02HM3MZ is the ICD-10-PCS code for a insertion procedure on the ventricular septum using a percutaneous approach with cardiac 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.

For a different body part, codes include 02H43MZ (coronary vein), 02H63MZ (right atrium), 02H73MZ (left atrium), 02HK3MZ (right ventricle), 02HL3MZ (left ventricle) and 02HN3MZ (pericardium).

With a different device, use 02HM3JZ (cardiac lead, pacemaker), 02HM3KZ (cardiac lead, defibrillator), 02HM3NZ (intracardiac pacemaker) and 02HM3YZ (other device).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 210 (Cardiac Pacemaker Revision or Device Replacement with MCC), DRG 211 (Cardiac Pacemaker Revision or Device Replacement without MCC), DRG 242 (Permanent Cardiac Pacemaker Implant with MCC), DRG 243 (Permanent Cardiac Pacemaker Implant with CC), DRG 244 (Permanent Cardiac Pacemaker Implant without CC/MCC) and DRG 275 (Cardiac Defibrillator Implant with Cardiac Catheterization and MCC), under the surgical categories “Cardiac Pacemaker Revision or Device Replacement”, “Permanent Cardiac Pacemaker Implant” and “Cardiac Defibrillator Implant with Cardiac Catheterization”.

It was added in FY2027, effective October 1, 2026.
