CPT code 01920 represents anesthesia services for patients undergoing coronary angiography and ventriculography when Swan–Ganz catheterization is not performed. This code captures the anesthesiologist’s role in providing peri-procedural sedation, airway and hemodynamic management, and anesthetic care specifically tied to invasive diagnostic cardiac imaging. Nationally, accurate use of this code affects clinical documentation, hospital billing, and payment for cardiac catheterization cases where anesthesia is required.

Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines payer coverage considerations and coding contexts relevant to these payers without presenting state-level variation.

Readers will find a concise clinical context for when 01920 is appropriate, comparisons to related anesthesia services, typical site-of-service considerations (hospital cath lab or cardiac interventional suite), common associated diagnoses encountered with these procedures, and related procedural codes to distinguish scope of service. The report also summarizes common modifiers and coding scenarios used with procedural anesthesia codes and highlights areas where documentation should align with the billed code. This information is intended to support accurate claim submission and coding consistency for anesthesia services tied to diagnostic coronary angiography and ventriculography.
