About 64634: Additional cervical/thoracic facet nerve ablation
Reports neurolytic treatment of each additional cervical or thoracic facet joint after the primary joint is treated during the same session.
This add-on describes neurolytic treatment of an additional cervical or thoracic facet joint, commonly by radiofrequency ablation of the medial branch nerves that supply the joint. Pain-management physicians typically perform the procedure for selected patients with facet-mediated neck or upper-back pain. Imaging guidance with fluoroscopy or CT is part of the service. The unit is the additional facet joint treated, not each nerve or lesion made.
Report 64634 with the primary cervical or thoracic facet-joint ablation code 64633; it cannot stand alone. The record should identify the treated spinal region and the additional joint or joints addressed, supporting the reported count. CMS treats this as an add-on paid within the primary procedure’s global period. For a bilateral procedure, modifier 50 is paid at 150%.

64634 billing questions
When is 64634 reported instead of 64633?
64633 reports the primary cervical or thoracic facet joint treated. Report 64634 for each additional facet joint treated in the same session.
Can 64634 be billed by itself?
No. It is an add-on code and must be reported with the primary procedure, 64633.
Is imaging guidance separately reported?
Fluoroscopic or CT guidance is included in the facet ablation service described by this code; do not separately report guidance for the same treatment.
What supports the number of units?
Document the cervical or thoracic region and each additional facet joint treated. Units represent additional joints, not the number of nerves lesioned.
How is bilateral treatment reported?
For a bilateral procedure, report modifier 50; CMS pays the bilateral procedure at 150%.
Where these rates come from
