About 02HN3MZ

02HN3MZ is the ICD-10-PCS code for a insertion procedure on the pericardium 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.

In plain terms, this corresponds to insertion or replacement of epicardial lead [electrode] into epicardium, the ICD-9-CM procedure title it maps to (37.74).

For a different body part, codes include 02H43MZ (coronary vein), 02H63MZ (right atrium), 02H73MZ (left atrium), 02HK3MZ (right ventricle), 02HL3MZ (left ventricle) and 02HM3MZ (ventricular septum).

The same procedure with a different approach is coded 02HN0MZ (open) and 02HN4MZ (percutaneous endoscopic).

With a different device, use 02HN30Z (monitoring device, pressure sensor), 02HN32Z (monitoring device), 02HN3JZ (cardiac lead, pacemaker), 02HN3KZ (cardiac lead, defibrillator) and 02HN3YZ (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) and DRG 211 (Cardiac Pacemaker Revision or Device Replacement without MCC), under the surgical category “Cardiac Pacemaker Revision or Device Replacement”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
