What 61736 covers
Code 61736 represents intracranial laser interstitial thermal therapy for one simple lesion reached along a single trajectory. A neurosurgeon places a laser probe stereotactically, when needed, and uses MRI guidance and thermometry to heat and ablate the target tissue. It is used in selected cases such as focal epilepsy or an intracranial tumor when LITT is the chosen treatment, typically in a hospital operating room with MRI-capable equipment.
Choose the code based on the documented lesion characteristics and trajectory, not simply the diagnosis: multiple trajectories or multiple or complex lesions point to 61737. Record the target, lesion details, number of trajectories, probe placement, and MRI-guided treatment. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. An assistant at surgery is not paid; co-surgeons and team surgery are not permitted.
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.

61736 billing questions
When should 61737 be used instead?
Use 61737 when the treatment involves multiple trajectories or multiple or complex lesions. Code 61736 describes one simple lesion treated along a single trajectory.
Is MRI guidance included in 61736?
Yes. The code accounts for MRI guidance used during the intracranial laser treatment, including MRI monitoring of the thermal ablation.
Should modifier 50 be appended for bilateral treatment?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not use modifier 50 to report bilateral treatment.
Can an assistant surgeon be paid for this procedure?
No. CMS lists a statutory restriction on assistant-at-surgery payment for 61736.
What documentation supports reporting 61736?
Document the lesion treated, why it fits the simple-lesion selection, the single trajectory, probe placement when performed, and MRI-guided ablation.
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.
