Stereotactic radiosurgery (particle beam, gamma ray, or linear accelerator); each additional spinal lesion (List separately in addition to code for primary procedure)

Stereotactic radiosurgery (SRS) is a non-invasive medical procedure that utilizes advanced technology to deliver high doses of radiation precisely to targeted areas within the body, specifically for treating spinal lesions. This technique employs various forms of radiation, including particle beams, gamma rays, or linear accelerators, to achieve its therapeutic effects. The primary goal of SRS is to destroy or shrink tumors while minimizing damage to surrounding healthy tissues. In the context of spinal lesions, SRS is particularly beneficial as it allows for the treatment of lesions located in challenging anatomical areas, where traditional surgical approaches may pose significant risks. The procedure is characterized by its ability to focus multiple intersecting beams of radiation on a single lesion, ensuring that the maximum dose is delivered directly to the tumor while sparing adjacent structures. This method is often performed in conjunction with advanced imaging techniques, such as three-dimensional MRI or CT scans, to accurately visualize the lesion and plan the treatment. The use of immobilization devices and fiducial markers further enhances the precision of the procedure, making it a preferred option for patients with specific spinal conditions.
