Neurosurgery
About 61737: Intracranial laser thermal ablation, complex
Reports intracranial laser interstitial thermal therapy involving multiple trajectories or multiple or complex lesions, performed to thermally ablate selected brain lesions.
A neurosurgeon uses stereotactic planning to guide laser probes through one or more small cranial openings and heat targeted intracranial tissue. The technique may be used for selected brain tumors or epileptogenic lesions when thermal ablation is the planned treatment. This code represents the more involved LITT service, such as treatment requiring multiple trajectories or addressing multiple or complex lesions; it is not the single-trajectory, single-simple-lesion service.
Select the code from the operative plan and report: documentation should identify the lesion or lesions treated, their relevant complexity, the trajectories used, and the ablation performed. The stereotactic work integral to the LITT service is not separately reported as another portion of this procedure. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For a qualifying bilateral procedure, modifier 50 applies and Medicare pays at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

61737 billing questions
How does this code differ from 61736?
61736 is for LITT using one trajectory to treat one simple lesion. Report 61737 when the service involves multiple trajectories or multiple or complex lesions.
Can stereotactic guidance be billed separately?
The stereotactic work integral to the LITT service is included in this procedure. Do not separately report that same work as a distinct service.
What documentation supports choosing 61737?
The operative report should describe the treated lesion or lesions, the reason the treatment is multiple or complex, the trajectories used, and the laser ablation performed.
How is a bilateral procedure reported?
For a qualifying bilateral procedure, report modifier 50; CMS pays the bilateral service at 150%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is allowed only when medical necessity is documented. 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 indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
