About 02H63MZ

02H63MZ is the ICD-10-PCS code for a insertion procedure on the right atrium 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 replacement of transvenous atrial and/or ventricular lead(s) [electrode], the ICD-9-CM procedure title it maps to (37.76).

For a different body part, codes include 02H43MZ (coronary vein), 02H73MZ (left atrium), 02HK3MZ (right ventricle), 02HL3MZ (left ventricle), 02HM3MZ (ventricular septum) and 02HN3MZ (pericardium).

The same procedure with a different approach is coded 02H60MZ (open) and 02H64MZ (percutaneous endoscopic).

With a different device, use 02H630Z (monitoring device, pressure sensor), 02H632Z (monitoring device), 02H633Z (infusion device), 02H63DZ (intraluminal device), 02H63JZ (cardiac lead, pacemaker), 02H63KZ (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), DRG 211 (Cardiac Pacemaker Revision or Device Replacement without MCC) and DRG 275 (Cardiac Defibrillator Implant with Cardiac Catheterization and MCC), under the surgical categories “Cardiac Pacemaker Revision or Device Replacement” and “Cardiac Defibrillator Implant with Cardiac Catheterization”.

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