May code 93623 be reported for an isoproterenol study postablation following a single catheter electrophysiologic study with induction of arrhythymia, ablation of supraventricular tachycardia, and postablation injection of isoproterenol?
Answer:
Although it is extremely unusual to record and pace from only one or two sites within the heart, there
are still occasional circumstances for which singlecatheter studies for either recording and/or pacing
might be undertaken. Because code 93623, Programmed stimulation and pacing after intravenous drug infusion (List separately in addition to code for primary procedure), is reportable only in conjunction with 93619 and 93620, code 93624, Electrophysiologic follow-up study with pacing and recording to test effectiveness of therapy, including induction or attempted induction of arrhythmia, is reported to describe follow-up electrophysiologic study of the efficacy of any therapy undertaken, including any therapy initiated, whether pharmacologic, surgical, or catheter ablation, or device therapy.
Also reportable is code 93618, Induction of arrhythmia by electrical pacing, which is used to report insertion of a single catheter for the purpose of inducing an arrhythmia. This procedure is rarely performed in and of itself because, in most instances, further evaluative studies and mapping of the arrhythmia would also be performed. Code 93651, Intracardiac catheter ablation of arrhythmogenic focus; for
treatment of supraventricular tachycardia by ablation of fast or slow atrioventricular pathways, accessory atrioventricular connections or other atrial foci, singly or in combination, is reported to describe the catheter ablation procedure.
Modifier 51 should not be appended to 93600, 93618, 93621-93623, and 93631.
