About 02H442Z

02H442Z is the ICD-10-PCS code for a insertion procedure on the coronary vein using a percutaneous endoscopic 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 other operations on vessels of heart, the ICD-9-CM procedure title it maps to (36.99).

For a different body part, codes include 02H642Z (right atrium), 02H742Z (left atrium), 02HK42Z (right ventricle), 02HL42Z (left ventricle), 02HN42Z (pericardium), 02HP42Z (pulmonary trunk) and 7 more.

The same procedure with a different approach is coded 02H402Z (open) and 02H432Z (percutaneous).

With a different device, use 02H440Z (monitoring device, pressure sensor), 02H443Z (infusion device), 02H44DZ (intraluminal device), 02H44JZ (cardiac lead, pacemaker), 02H44KZ (cardiac lead, defibrillator), 02H44MZ (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.
