CPT 92978: Intravascular Imaging and Interpretation for Coronary Vessel
CPT code 92978 denotes an add-on intravascular imaging and interpretation procedure performed during coronary catheterization procedures. The code captures imaging of the initial coronary vessel or graft using intravascular ultrasound (IVUS) or optical coherence tomography (OCT) to assess lesion morphology, stent placement, or residual disease before or after therapeutic intervention. Nationally, accurate reporting of 92978 supports clinical documentation of coronary imaging adjuncts and informs payment for complex percutaneous coronary procedures.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coding intent and clinical context, payer coverage considerations, and benchmarking information where available. The publication summarizes common billing scenarios for intravascular imaging add-on reporting, highlights documentation elements tied to image acquisition and interpretation, and outlines areas where policy updates or insurer-specific guidance commonly affect claim adjudication.
This resource is designed for coding managers, interventional cardiology clinicians, and revenue cycle staff seeking a clear national-level reference for CPT code 92978, including operational implications for procedure reporting and claims processing.

Billing Code Overview
CPT code 92978 is an add-on intravascular imaging and interpretation procedure used when a provider advances a catheter into a coronary vessel or previously placed graft and uses intravascular ultrasound or optical coherence tomography to visualize the extent of a blockage, stent placement, or other coronary anatomy before or after therapeutic intervention. The provider interprets the acquired images and reports the findings. Use of CPT code 92978 reports imaging of the initial vessel.
Service type: Intravascular imaging and interpretation (diagnostic imaging adjunct to coronary interventions)
Typical site of service: Cardiac catheterization laboratory or interventional cardiology suite (inpatient or outpatient hospital setting; may also occur in ambulatory surgery centers where coronary interventions are performed)
