What 61798 covers
This code represents single-session stereotactic radiosurgery directed at a complex intracranial lesion. Neurosurgeons and radiation oncologists commonly participate in treating brain metastases, meningiomas, and vestibular schwannomas with focused radiation using stereotactic localization and treatment planning. The service is typically delivered in a hospital or radiation-treatment setting without open removal of the lesion.
Report 61798 for the first complex lesion in the session; report 61799 for each additional complex lesion. Choose the complex rather than simple sequence based on the documented lesion classification, not lesion count or laterality alone. Records should identify the treated target or targets, support their complex classification, and document stereotactic planning and treatment. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care for 90 days. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate, including when targets are on both sides of the brain.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

61798 billing questions
How is 61798 distinguished from 61796?
61798 is for a complex cranial lesion; 61796 is the corresponding simple-lesion code. Use the documented CPT complexity classification rather than assuming that lesion size, location, or count alone determines the level.
How are multiple complex lesions reported?
Report 61798 for the first complex lesion treated in the session and 61799 for each additional complex lesion. Document the targets and which lesions are additional.
Should modifier 50 be used for lesions on both sides?
No. Bilateral adjustment is not appropriate for this code; report applicable additional-lesion services using the complex-lesion sequence.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after the procedure.
Can an assistant or co-surgeon be reported?
CMS permits assistant-at-surgery payment for this code. Co-surgeons and team surgery are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
