Electrophysiologic Testing and Pacemaker Services (Summer 1994)
Summer 1994 pages 10-26 Electrophysiologic Testing and Pacemaker Services Figure 1 - Conduction System Figure 2 - Electrical Conduction of the Heart Background Information The practice of cardiac electrophysiology has rapidly evolved from a purely diagnostic tool to a significant new therapeutic modality for the treatment of patients with cardiac arrhythmias. This evolution is similar to that which occurred for cardiac catheterization which began simply as a method of imaging cardiac and coronary structures, and evolved to a fully therapeutic practice. Technologic advances in permanent pacing have also continued. Many of the CPT codes and descriptors used prior to...

Article Overview
This article reviews the 1994 CPT revisions for electrophysiology, pacing, ablation, and implantable defibrillator services. It is aimed at coders, billers, and clinicians who need a broad understanding of how the article organizes diagnostic testing, therapeutic procedures, device implantation, and follow-up analysis for cardiac rhythm management. The discussion covers general electrophysiology concepts, major service categories, and the related CPT descriptors in a way that helps readers determine whether the full article is relevant to their work.
Why This Topic Matters
Cardiac electrophysiology and device services changed substantially in this period, and the article summarizes the updated CPT structure used to report those services. It is useful for understanding how the article frames procedure categories, device management, and follow-up monitoring in relation to coding workflow and specialty practice.
