About 02HW32Z

02HW32Z is the ICD-10-PCS code for a insertion procedure on the thoracic aorta, descending using a percutaneous 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 arterial catheterization, the ICD-9-CM procedure title it maps to (38.91).

For a different body part, codes include 02H432Z (coronary vein), 02H632Z (right atrium), 02H732Z (left atrium), 02HK32Z (right ventricle), 02HL32Z (left ventricle), 02HN32Z (pericardium) and 7 more.

The same procedure with a different approach is coded 02HW02Z (open) and 02HW42Z (percutaneous endoscopic).

With a different device, use 02HW30Z (monitoring device, pressure sensor), 02HW33Z (infusion device), 02HW3DZ (intraluminal device), 02HW3RZ (short-term external heart assist system) and 02HW3YZ (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.
