About 02H643Z

02H643Z is the ICD-10-PCS code for a insertion procedure on the right atrium using a percutaneous endoscopic approach with infusion device. 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 Cardiotomy, the ICD-9-CM procedure title it maps to (37.11).

For a different body part, codes include 02H443Z (coronary vein), 02H743Z (left atrium), 02HK43Z (right ventricle), 02HL43Z (left ventricle), 02HP43Z (pulmonary trunk), 02HQ43Z (right pulmonary artery) and 6 more.

The same procedure with a different approach is coded 02H603Z (open) and 02H633Z (percutaneous).

With a different device, use 02H640Z (monitoring device, pressure sensor), 02H642Z (monitoring device), 02H64DZ (intraluminal device), 02H64JZ (cardiac lead, pacemaker), 02H64KZ (cardiac lead, defibrillator), 02H64MZ (cardiac lead) and 2 more.

It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC) and DRG 229 (Other Cardiothoracic Procedures without MCC), under the surgical category “Other Cardiothoracic Procedures”.

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