CPT® Code 76940

Ultrasound guidance for parenchymal tissue ablation, as described by CPT® Code 76940, involves the use of ultrasound technology to assist in the precise targeting and monitoring of ablation procedures performed on parenchymal tissues, which are the functional tissues of organs or glands. This technique is particularly relevant in the context of microwave ablation (MVA) or radiofrequency ablation (RVA), where the goal is to destroy tumor cells or abnormal tissue within an organ. The ultrasound serves a dual purpose: first, it helps in mapping the treatment area to ensure accurate placement of the ablation instruments, and second, it allows for real-time monitoring of the ablation process. By visualizing the tissue and the ablation site, the physician can assess the effectiveness of the treatment and determine when sufficient ablation has occurred. The use of ultrasound in this context is critical for enhancing the safety and efficacy of the procedure, ensuring that the targeted tissue is adequately treated while minimizing damage to surrounding healthy structures. Code 76940 specifically captures the ultrasound guidance utilized during these separately reportable tissue ablation procedures.
