What 93618 covers
In an electrophysiology lab, a physician uses stimulation through intracardiac catheter electrodes to provoke an arrhythmia during diagnostic testing. The induced rhythm can help characterize an electrical abnormality in a patient being evaluated for a suspected arrhythmia. This code identifies induction by pacing, rather than pacing alone or recording electrical activity without induction.
Medicare assigns CPT 93618 physician fee schedule status C, or carrier priced: the Medicare Administrative Contractor sets payment for each claim. The diagnostic test has professional and technical components. Modifier 26 identifies the professional interpretation, modifier TC identifies the technical service, and reporting without either modifier represents the global service. The code has a 0-day global period, with same-day preoperative and postoperative care included.
