About 02HW33Z
02HW33Z is the ICD-10-PCS code for a insertion procedure on the thoracic aorta, descending using a percutaneous approach with infusion 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 02H433Z (coronary vein), 02H633Z (right atrium), 02H733Z (left atrium), 02HK33Z (right ventricle), 02HL33Z (left ventricle), 02HP33Z (pulmonary trunk) and 6 more.
The same procedure with a different approach is coded 02HW03Z (open) and 02HW43Z (percutaneous endoscopic).
With a different device, use 02HW30Z (monitoring device, pressure sensor), 02HW32Z (monitoring 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.
