Stereotactic localization, including burr hole(s), with insertion of catheter(s) or probe(s) for placement of radiation source

Stereotactic localization, as described by CPT® Code 61770, is a precise medical procedure that involves the use of advanced imaging techniques to accurately locate and treat brain tumors. This procedure is characterized by the application of a stereotactic head frame, which stabilizes the patient's head and ensures accurate targeting of the lesion. The process begins with stereotactic computed tomography (CT) imaging, often enhanced with contrast, to visualize the tumor's location and size, allowing for optimal planning of the intervention. Following imaging, a surgical incision is made to expose the skull, where one or more burr holes are drilled. These burr holes serve as access points for the insertion of catheters or probes, which are essential for delivering radiation therapy directly to the tumor site. The procedure involves creating tracks in the brain tissue, which are carefully dilated to accommodate the probes or catheters. Once positioned, the radiation source delivery system is attached to the head frame, and radiation monitors are utilized to ensure accurate dosing during treatment. After the prescribed radiation dose is administered, the catheters or probes are removed, and the incision is sutured closed. This meticulous approach allows for targeted treatment of brain tumors while minimizing damage to surrounding healthy tissue.
