About 02H70KZ

02H70KZ is the ICD-10-PCS code for a insertion procedure on the left atrium using an open 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 of automatic cardioverter/defibrillator lead(s) only, the ICD-9-CM procedure title it maps to (37.95).

For a different body part, codes include 02H40KZ (coronary vein), 02H60KZ (right atrium), 02HK0KZ (right ventricle), 02HL0KZ (left ventricle) and 02HN0KZ (pericardium).

The same procedure with a different approach is coded 02H73KZ (percutaneous) and 02H74KZ (percutaneous endoscopic).

With a different device, use 02H700Z (monitoring device, pressure sensor), 02H702Z (monitoring device), 02H703Z (infusion device), 02H70DZ (intraluminal device), 02H70JZ (cardiac lead, pacemaker), 02H70MZ (cardiac lead) and 2 more.

It is an operating-room procedure in the MS-DRG logic for DRG 265 (AICD Lead Procedures) and DRG 275 (Cardiac Defibrillator Implant with Cardiac Catheterization and MCC), under the surgical categories “AICD Lead Procedures” and “Cardiac Defibrillator Implant with Cardiac Catheterization”.

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