CPT code 0944T represents an advanced imaging-based planning service that creates a 3D simulation for microwave ablation of one or more liver lesions. The service models lesion and surrounding tissue, calculates planned ablation volumes, overlays the plan on CT images, and compares volumes before and after the procedure to document treatment effectiveness. This code matters nationally as image-guided ablation and image-based planning become more common in interventional oncology, affecting coding, coverage, and payment for hospitals and ambulatory surgery centers.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical context for use of the code, typical sites of service, and what to expect in payer coverage patterns and billing workflows. The summary synthesizes benchmarks where available and highlights policy considerations such as documentation of simulation steps and imaging integration into the operative record.

The publication provides a concise reference for coding teams, interventional radiologists, and revenue cycle staff: it outlines the service components captured by 0944T, summarizes common payer approaches to advanced imaging and simulation services, and identifies practical documentation elements needed to support billing.
