CPT® Code 77432

Stereotactic radiation treatment management is a specialized procedure aimed at addressing cranial lesions through a highly focused application of radiation. This treatment is characterized by its precision, targeting specific areas within the cranial cavity while minimizing exposure to surrounding healthy tissues. The complete course of treatment, as defined by CPT® Code 77432, consists of a single session, which is often sufficient for certain medical conditions. Conditions that may benefit from this approach include both benign and malignant intracranial tumors, such as primary tumors and metastatic lesions, as well as specific disorders like acoustic neuromas, meningiomas, pituitary adenomas, arteriovenous malformations, and trigeminal neuralgia that have not responded to other therapeutic interventions. The procedure utilizes advanced technology to deliver a high dose of ionizing radiation, which can be generated by gamma rays or linear accelerators, ensuring maximum effectiveness in ablating the targeted tissue. The management of this treatment involves comprehensive professional oversight, including the review of various imaging modalities—such as X-rays, angiography, CT scans, MRI, and PET scans—to accurately localize the lesion. Additionally, the process includes patient positioning stabilization, meticulous treatment planning that considers the number of isocenters, the configuration of arcs or angles, and the specifics of beam delivery, including their number, size, and weight. The isodose distribution is carefully prescribed and calculated, followed by setup and accuracy verification testing, and simulation of the prescribed treatment arcs or fixed portals. It is important to note that CPT® Code 77432 is billed only once for the entire course of treatment, reflecting the comprehensive nature of this single-session approach.
