2007 ICD-9-CM Procedure 92.3 Stereotactic radiosurgery (STAIR-ee-o-TAK-tik...) A radiation therapy technique involving a rigid head frame that is attached to the skull; high-dose radiation is administered through openings in the head frame to the tumor while decreasing the amount of radiation given to normal brain tissue. This procedure does not involve surgery. A stereotactic neurosurgery in which the usual rigid needles or probes are replaced with beams of ionizing radiation directed toward an intracranial target so as to achieve local tissue destruction. No skin incision or skull opening is required. It is performed with the "gamma knife", a self-contained unit with 201 cobalt-60 sources or with an isocentric linear accelerator (linac).
