The CPT® Code 77413 refers to a specific type of radiation treatment delivery that involves the administration of radiation to three or more separate treatment areas within the body. This procedure is designed to target and destroy tumors effectively by utilizing a radiation beam with an energy level ranging from 6 to 10 megavolts (MeV). The use of custom blocking, tangential ports, wedges, rotational beams, and compensators are integral components of this treatment, allowing for precise targeting of the affected areas while minimizing exposure to surrounding healthy tissues. The application of electron beams in this context further enhances the treatment's effectiveness, particularly for certain types of tumors. It is important to note that different codes are designated for varying energy levels of radiation beams, with Code 77414 applicable for beams ranging from 11 to 19 MeV, and Code 77416 for beams of 20 MeV or higher. This structured approach to radiation therapy is crucial for optimizing patient outcomes and ensuring that the treatment is tailored to the specific needs of each individual patient.
