About 02H43KZ

02H43KZ is the ICD-10-PCS code for a insertion procedure on the coronary vein using a percutaneous approach with cardiac lead, defibrillator. 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 implantation or replacement of transvenous lead [electrode] into left ventricular coronary venous system, the ICD-9-CM procedure title it maps to (00.52).

For a different body part, codes include 02H63KZ (right atrium), 02H73KZ (left atrium), 02HK3KZ (right ventricle), 02HL3KZ (left ventricle), 02HM3KZ (ventricular septum) and 02HN3KZ (pericardium).

The same procedure with a different approach is coded 02H40KZ (open) and 02H44KZ (percutaneous endoscopic).

With a different device, use 02H430Z (monitoring device, pressure sensor), 02H432Z (monitoring device), 02H433Z (infusion device), 02H43DZ (intraluminal device), 02H43JZ (cardiac lead, pacemaker), 02H43MZ (cardiac lead) and 2 more.

It is an operating-room procedure in the MS-DRG logic for DRG 265 (AICD Lead Procedures), under the surgical category “AICD Lead Procedures”.

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