About 02HW3RZ

02HW3RZ is the ICD-10-PCS code for a insertion procedure on the thoracic aorta, descending using a percutaneous approach with short-term external heart assist system. 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.

For a different body part, codes include 02HA3RZ (heart).

With a different device, use 02HW30Z (monitoring device, pressure sensor), 02HW32Z (monitoring device), 02HW33Z (infusion device), 02HW3DZ (intraluminal device) and 02HW3YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 215 (Other Heart Assist System Implant), under the surgical category “Other Heart Assist System Implant”.
