Pain management
About 64635: Lumbar or sacral facet nerve ablation
Reports image-guided ablation of nerves supplying the first lumbar or sacral facet joint treated during a session for facet-mediated spinal pain.
An interventional pain physician typically uses a radiofrequency probe to create a lesion in nerves supplying a lumbar or sacral facet joint. Fluoroscopy or CT guides probe placement. The procedure is commonly considered for persistent axial low-back pain attributed to facet joints, often after diagnostic medial branch blocks. The target is the nerve supply to the joint, not the joint tissue itself.
Report 64635 for the first lumbar or sacral facet joint treated in the session; report 64636 for each additional joint. Document the spinal levels and sides treated, the image-guided technique, and the ablation performed. Imaging guidance is part of the service. CMS assigns a 10-day global period, so related postoperative visits in that period are included. For bilateral treatment, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery is not paid; co-surgeon and team-surgery billing are not permitted.

64635 billing questions
When do I report 64635 instead of 64636?
Use 64635 for the first lumbar or sacral facet joint treated in the session. Use 64636 for each additional joint.
Does the code count nerves, lesions, or facet joints?
The reporting unit is the facet joint treated, not each nerve or lesion. Document the treated levels and laterality to support the unit count.
Can fluoroscopy or CT guidance be billed separately?
Imaging guidance is included in the ablation service described by this code. Do not report separate guidance for the same procedure.
How is bilateral treatment reported?
CMS identifies this as a bilateral procedure; modifier 50 is paid at 150%. Document treatment on both sides.
What happens when another procedure is performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the others at 50%. Related postoperative visits are included during the 10-day global period.
Can an assistant or co-surgeon be billed?
CMS does not pay an assistant at surgery for this code. Co-surgeon and team-surgery billing are not permitted.
