About 02H702Z

02H702Z is the ICD-10-PCS code for a insertion procedure on the left atrium using an open approach with monitoring 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 02H402Z (coronary vein), 02H602Z (right atrium), 02HK02Z (right ventricle), 02HL02Z (left ventricle), 02HN02Z (pericardium), 02HP02Z (pulmonary trunk) and 7 more.

The same procedure with a different approach is coded 02H732Z (percutaneous) and 02H742Z (percutaneous endoscopic).

With a different device, use 02H700Z (monitoring device, pressure sensor), 02H703Z (infusion device), 02H70DZ (intraluminal device), 02H70JZ (cardiac lead, pacemaker), 02H70KZ (cardiac lead, defibrillator), 02H70MZ (cardiac lead) and 2 more.

It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC), DRG 229 (Other Cardiothoracic Procedures without MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Other Cardiothoracic Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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