CPT® Code 77280

Therapeutic radiology simulation-aided field setting is a crucial procedure in the field of radiation oncology, aimed at accurately identifying both normal and abnormal anatomical structures within the targeted treatment area. This process involves the acquisition of images and data that are essential for planning effective radiation therapy. During the simulation, a radiation oncologist or a qualified healthcare professional employs specialized simulation equipment, which may include dedicated simulators, radiation treatment units, or diagnostic X-ray machines. The primary goal of this procedure is to establish the optimal treatment position for the patient, ensuring that the radiation is delivered precisely to the intended area while minimizing exposure to surrounding healthy tissues.

In the course of the simulation, several key steps are undertaken. These include the design of immobilization devices, if necessary, to keep the patient in a stable position throughout the treatment. Localization lasers are utilized to align the patient accurately, and the skin is marked with targeting markers or tattoos to provide visual references for the radiation delivery. The oncologist visualizes the treatment ports or fields in relation to anatomical landmarks, which is critical for effective treatment planning. Additionally, all parameters recorded during the simulation are meticulously documented to ensure that the treatment plan is based on accurate and comprehensive data. The specific CPT® code 77280 is designated for reporting the simulation of a single area of interest, which may involve a single port or simple parallel opposed ports with minimal or no blocking, distinguishing it from more complex simulation procedures that are reported with other codes.
