Code EP Components in Rare Cases

Question: How should I bill for a ventricular stimulation and right ventricle recording with the induction of arrhythmia? I’m used to seeing comprehensive EP studies, so I don’t know if I should report individual components or use modifier 52 on a comprehensive code.

Answer: In cases where the cardiologist doesn’t perform a complete electrophysiology (EP) study, you should report codes for the individual components that the cardiologist performed rather than using modifier 52 (Reduced services) on a comprehensive code. In this case, you’ll report the following codes:

  • 93603, Right ventricular recording
  • 93612, Intraventricular pacing
  • 93618, Induction of arrhythmia by electrical pacing.

Assuming the cardiologist performed the services in a facility, you should append modifier 26 (Professional component) to each of the listed codes to indicate you’re reporting only the professional component.

Also note that the Medicare Physician Fee Schedule lists all of the above codes as carrier-priced, which means the MAC gets to decide whether to cover the code and how much to reimburse for it.
