About 02HA0RZ
02HA0RZ is the ICD-10-PCS code for a insertion procedure on the heart using an open 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 02HA3RZ (percutaneous) and 02HA4RZ (percutaneous endoscopic).
With a different device, use 02HA0QZ (implantable heart assist system) and 02HA0YZ (other device).
It is an operating-room procedure in the MS-DRG logic for 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 category “Heart Transplant or Implant of Heart Assist System”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
