About 02HW00Z

02HW00Z is the ICD-10-PCS code for a insertion procedure on the thoracic aorta, descending using an open approach with monitoring device, pressure sensor. 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 insertion of intra-aneurysm sac pressure monitoring device (intraoperative), the ICD-9-CM procedure title it maps to (00.58).

For a different body part, codes include 02H400Z (coronary vein), 02H600Z (right atrium), 02H700Z (left atrium), 02HK00Z (right ventricle), 02HL00Z (left ventricle), 02HN00Z (pericardium) and 7 more.

The same procedure with a different approach is coded 02HW30Z (percutaneous) and 02HW40Z (percutaneous endoscopic).

With a different device, use 02HW02Z (monitoring device), 02HW03Z (infusion device), 02HW0DZ (intraluminal device) and 02HW0YZ (other device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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