    CPT 77372: Stereotactic Radiosurgery, Technical Component

    Medicare pays $978 on average nationally for this procedure.

    CPT code 77372 describes the technical component of stereotactic radiosurgery using a linear accelerator to deliver precisely targeted, externally generated ionizing radiation to small intracranial lesions; the service type is stereotactic radiosurgery technical component and the typical site of service is an outpatient radiation oncology department or hospital-based radiation facility where a three-dimensional coordinate system is used to localize and treat brain targets.

    For related coverage guidance, see recent payer policy updates: Clinical Review Criteria Intraoperative Neurophysiological Monitoring (IONM), Remote Electrical Neuromodulation for Migraines (i.e., Nerivio®), Lumbar Microdiscectomy.

    Clinical & Coding Specifications

    Clinical Context

    A 62-year-old patient with a solitary intracranial metastasis from non-small cell lung cancer presents with a 1.8 cm enhancing lesion in the right frontal lobe on MRI. The multidisciplinary tumor board recommends stereotactic radiosurgery (SRS) using a linear accelerator to deliver a single high-dose, highly conformal treatment to the target while sparing surrounding brain. The clinical workflow includes: pretreatment consultation and review of prior imaging; immobilization and stereotactic localization using a three-dimensional coordinate system; high-resolution treatment planning with fused diagnostic MRI and planning CT; dosimetric review and quality assurance checks; delivery of the stereotactic radiosurgery treatment (technical component billed under 77372); and post-treatment follow-up with repeat MRI at 6–12 weeks and clinical surveillance. Typical site of service is an outpatient radiation oncology department or hospital radiation therapy suite equipped for stereotactic radiosurgery.
