37.65 — Implant of single ventricular (extracorporeal) external heart assist system
About ICD-9-CM 37.65
37.65 is an ICD-9-CM procedure code for implant of single ventricular (extracorporeal) external heart assist system. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.
The CMS General Equivalence Mappings translate it to 4 ICD-10-PCS codes, such as 02HA0RZ (Insertion of Short-term External Heart Assist System into Heart, Open Approach), 02HA4RZ (Insertion of Short-term External Heart Assist System into Heart, Percutaneous Endoscopic Approach) and 5A02116 (Assistance with Cardiac Output using Other Pump, Intermittent). All of these are approximate matches, so review the record to pick the right one. Some mappings are combinations: more than one ICD-10 code is needed to fully express the ICD-9 code.
