What 93600 covers
An electrode catheter records electrical activity from the His bundle, a conduction pathway between the atria and ventricles. Electrophysiologists use the recording to evaluate cardiac conduction and arrhythmias, usually during an invasive electrophysiology study in a hospital electrophysiology or cardiac catheterization lab. The code describes the His-bundle recording itself, rather than a comprehensive evaluation of multiple cardiac sites.
Medicare assigns status C under the physician fee schedule: there is no national payment, and the Medicare Administrative Contractor sets payment for each claim. This is a diagnostic test with professional and technical portions. Report modifier 26 for the interpretation, modifier TC for the equipment and staff, or no modifier for the global service. The procedure has a 0-day global period, which includes same-day preoperative and postoperative care.

93600 billing questions
When should I report this instead of 93602 or 93603?
Report 93600 for recording from the His bundle. Code 93602 identifies an intra-atrial recording, while 93603 identifies a right ventricular recording.
How does this differ from a comprehensive EP evaluation?
93600 describes a His-bundle recording. A comprehensive EP evaluation code, such as 93619, describes a broader electrophysiologic study.
Which modifier identifies the interpretation?
Use modifier 26 for the professional interpretation. Modifier TC identifies the technical portion; reporting without either modifier represents the global service.
Does Medicare publish a national payment for this code?
No. Medicare assigns status C, so the Medicare Administrative Contractor sets payment for each claim.
What global period applies?
The code has a 0-day global period. Same-day preoperative and postoperative care is included.
