CPT code 92979 denotes an add-on intravascular imaging procedure performed during coronary interventions, using intravascular ultrasound (IVUS) or optical coherence tomography (OCT) to visualize additional coronary vessels or previously placed grafts and to interpret and report those images. This code matters nationally because intravascular imaging guides stent placement and therapeutic decision-making, affecting procedural quality, outcomes, and downstream resource use.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent and service context, a summary of common modifiers and administrative considerations, and linkage to related procedural and billing themes. The publication outlines benchmarks and coverage patterns where available, clarifies typical site-of-service coding (cardiac catheterization laboratory), and situates CPT code 92979 within intraprocedural imaging workflows.

This summary equips clinicians, billing professionals, and policy analysts with a clear understanding of what CPT code 92979 represents, why it is used during coronary interventions, and what topics to review next — including payer coverage nuances, coding relationships, and where to find additional clinical or policy guidance.
