CPT code 93616 denotes placement of an esophageal catheter with a recording electrode tip to deliver pacing impulses and record esophageal atrial electrograms, with optional ventricular recording. This procedure supports cardiac electrophysiology assessment and can be used for diagnostic evaluation of arrhythmias, atrial conduction, and for temporary pacing during testing. Nationally, the code matters because it captures both professional and technical components of a specialized diagnostic service performed in procedural settings, affecting provider billing and resource planning for electrophysiology services.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of clinical context for esophageal electrogram placement, typical sites of service, and what the code represents for billing workflows. The publication outlines expected benchmarks where available, common modifier usage from the input, and policy or coverage considerations relevant to major national payers. It also summarizes implications for coding accuracy and documentation to support claims for combined technical and professional services.
