What 93602 covers

An electrophysiology team uses an intracardiac catheter to record electrical signals from an atrium during testing for arrhythmias or abnormal cardiac conduction. The recording may help the electrophysiologist assess atrial activation and the timing of electrical events. It is performed in an electrophysiology laboratory, commonly in a hospital setting, as part of an invasive diagnostic study.

Medicare assigns status C under the Physician Fee Schedule: there is no national payment amount, and the Medicare Administrative Contractor determines payment for the claim. The service has professional and technical components; modifier 26 identifies interpretation, modifier TC identifies the equipment and staff portion, and no modifier represents the global service. The service has a 0-day global period, with same-day preoperative and postoperative care included. Report the recording performed, distinguishing it from recordings at other cardiac sites and from pacing procedures.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

93600His bundle recordingIntracardiac signal
Use 93602 for atrial electrical recording; 93600 identifies recording at the bundle of His.
93603Ventricular recordingRight ventricle
Use 93602 for an atrial recording and 93603 for a recording in the right ventricle.
93610Intracardiac pacingAtrial chamber
93602 captures atrial electrical signals. Code 93610 is for pacing in the atrium.
93615Esophageal recordingWithout pacing
93615 identifies esophageal recording, using an electrode in the esophagus; 93602 is for recording within an atrium.
