About 02HL3MZ

02HL3MZ is the ICD-10-PCS code for a insertion procedure on the left ventricle 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 initial insertion of transvenous lead [electrode] into ventricle, the ICD-9-CM procedure title it maps to (37.71).

For a different body part, codes include 02H43MZ (coronary vein), 02H63MZ (right atrium), 02H73MZ (left atrium), 02HK3MZ (right ventricle), 02HM3MZ (ventricular septum) and 02HN3MZ (pericardium).

The same procedure with a different approach is coded 02HL0MZ (open) and 02HL4MZ (percutaneous endoscopic).

With a different device, use 02HL30Z (monitoring device, pressure sensor), 02HL32Z (monitoring device), 02HL33Z (infusion device), 02HL3DZ (intraluminal device), 02HL3JZ (cardiac lead, pacemaker), 02HL3KZ (cardiac lead, defibrillator) and 2 more.

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.
