About 02HM3NZ

02HM3NZ is the ICD-10-PCS code for a insertion procedure on the ventricular septum using a percutaneous approach with intracardiac pacemaker. 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 02H43NZ (coronary vein), 02H63NZ (right atrium), 02H73NZ (left atrium), 02HK3NZ (right ventricle) and 02HL3NZ (left ventricle).

With a different device, use 02HM3JZ (cardiac lead, pacemaker), 02HM3KZ (cardiac lead, defibrillator), 02HM3MZ (cardiac lead) and 02HM3YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC) and DRG 229 (Other Cardiothoracic Procedures without MCC), under the surgical category “Other Cardiothoracic Procedures”.

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