Stereotactic radiosurgery
About 61797: Additional simple cranial radiosurgery lesion
Reports treatment of each additional simple cranial target during stereotactic radiosurgery, alongside the primary code for a simple lesion.
Code 61797 represents stereotactic radiosurgery directed at an additional simple intracranial lesion during a treatment session. SRS delivers focused radiation to a cranial target without open surgical removal; clinical targets may include brain metastases or other intracranial lesions selected for radiosurgical treatment. Neurosurgeons and radiation oncologists commonly participate in planning and treatment, often in a hospital or specialized radiosurgery setting.
Report 61797 for each additional simple lesion treated, with 61796 as the primary procedure for the simple-lesion treatment. The record should identify the lesions treated, support their classification as simple, and document the radiosurgery plan and delivered treatment. This is an add-on code: it is not billed alone, and Medicare payment falls within the primary procedure’s global period.
