About 02HW40Z
02HW40Z is the ICD-10-PCS code for a insertion procedure on the thoracic aorta, descending using a percutaneous endoscopic 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 02H440Z (coronary vein), 02H640Z (right atrium), 02H740Z (left atrium), 02HK40Z (right ventricle), 02HL40Z (left ventricle), 02HN40Z (pericardium) and 7 more.
The same procedure with a different approach is coded 02HW00Z (open) and 02HW30Z (percutaneous).
With a different device, use 02HW42Z (monitoring device), 02HW43Z (infusion device), 02HW4DZ (intraluminal device) and 02HW4YZ (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.
