About 02HT42Z

02HT42Z is the ICD-10-PCS code for a insertion procedure on the left pulmonary 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 incision of vessel, other thoracic vessels, the ICD-9-CM procedure title it maps to (38.05).

For a different body part, codes include 02H442Z (coronary vein), 02H642Z (right atrium), 02H742Z (left atrium), 02HK42Z (right ventricle), 02HL42Z (left ventricle), 02HN42Z (pericardium) and 7 more.

The same procedure with a different approach is coded 02HT02Z (open) and 02HT32Z (percutaneous).

With a different device, use 02HT40Z (monitoring device, pressure sensor), 02HT43Z (infusion device), 02HT4DZ (intraluminal device) and 02HT4YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC) and DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), under the surgical category “Other Major Cardiovascular Procedures”.

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