Functional neurosurgery

About 61735: Stereotactic intracranial lesioning for movement disorder

Reports unilateral stereotactic radiofrequency lesioning of intracranial neural tissue to treat a movement disorder, such as tremor or Parkinson disease.

This service is stereotactic radiofrequency lesioning of a deep intracranial target to manage a movement disorder. A functional neurosurgeon typically performs it in an operating room, using stereotactic equipment to guide treatment. Clinical contexts may include selected patients with tremor, Parkinson disease, or dystonia when an ablative approach is chosen. The code represents a unilateral procedure; document the treated side and target, the movement disorder being addressed, and the operative technique.

Report this code when the surgeon performs the described intracranial lesioning, rather than implanting stimulation electrodes or using focused ultrasound. It has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is barred; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

61735 billing questions

How does this differ from MR-guided focused ultrasound?

This code is for stereotactic intracranial radiofrequency lesioning. Use 61715 for the distinct MR-guided focused ultrasound ablation approach.

Is this a deep brain stimulation electrode implantation code?

No. This code describes lesioning neural tissue; 61863 and 61867 describe implantation of neurostimulator electrodes.

Can modifier 50 be used for bilateral treatment?

No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 is not appropriate.

What documentation supports reporting the service?

Document the movement disorder, intracranial target, treated side, stereotactic approach, and radiofrequency lesioning performed.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is barred. Co-surgeon payment is available only with supporting documentation; team surgery is not permitted.
