CPT code 93600 denotes a diagnostic electrophysiologic recording of the heart’s conduction system at the bundle of His. This specialized test documents the electrical signals responsible for coordinating heartbeats and supports evaluation of conduction abnormalities, syncope, or arrhythmias. Nationally, accurate coding for this procedure affects clinical workflow, episode-of-care documentation, and interactions with major payers.

Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what CPT code 93600 represents, the typical clinical and facility contexts where it is performed, and the payer landscape relevant to coverage and claims processing. The publication summarizes available benchmarks, notes recent policy or reimbursement considerations where applicable, and situates the procedure within broader cardiac electrophysiology practice.

This analysis is intended for clinicians, coding professionals, and health plan administrators seeking a clear, national-level understanding of the code’s clinical meaning, billing context, and payer relevance. Data not available in the input will be identified as such in the detailed sections.
