Answer: Begin with diagnosis code 780.2 (Syncope and collapse). The surgical code for implantation is 33282 (Implantation of patient-activated cardiac event recorder). This crosses to anesthesia code 00530 (Anesthesia for permanent transvenous catheter insertion). You'll also report 00530 for the follow-up procedure if the surgeon removes the recorder at a later date.
Before coding, remember that light sedation technically does not require an anesthesiologist's care. Be sure he administered a MAC anesthetic and you have appropriate documentation before you code the case.
