About 02HA4RZ

02HA4RZ is the ICD-10-PCS code for a insertion procedure on the heart using a percutaneous endoscopic 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.

In plain terms, this corresponds to insertion of temporary non-implantable extracorporeal circulatory assist device and implant of single ventricular (extracorporeal) external heart assist system, the ICD-9-CM procedure titles it maps to (37.62 and 37.65).

The same procedure with a different approach is coded 02HA0RZ (open) and 02HA3RZ (percutaneous).

With a different device, use 02HA4QZ (implantable heart assist system) and 02HA4YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 215 (Other Heart Assist System Implant), DRG 001 (Heart Transplant or Implant of Heart Assist System with MCC) and DRG 002 (Heart Transplant or Implant of Heart Assist System without MCC), under the surgical categories “Other Heart Assist System Implant” and “Heart Transplant or Implant of Heart Assist System”.

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