What 64634 covers
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%.
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.

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
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.
