About 02H40NZ

02H40NZ is the ICD-10-PCS code for a insertion procedure on the coronary vein using an open approach with intracardiac pacemaker. 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.

For a different body part, codes include 02H60NZ (right atrium), 02H70NZ (left atrium), 02HK0NZ (right ventricle) and 02HL0NZ (left ventricle).

The same procedure with a different approach is coded 02H43NZ (percutaneous) and 02H44NZ (percutaneous endoscopic).

With a different device, use 02H400Z (monitoring device, pressure sensor), 02H402Z (monitoring device), 02H403Z (infusion device), 02H40DZ (intraluminal device), 02H40JZ (cardiac lead, pacemaker), 02H40KZ (cardiac lead, defibrillator) 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 was added in FY2017, effective October 1, 2016.
