Interventional pain
About 64633: Cervical or thoracic facet radiofrequency ablation
Reports radiofrequency lesioning of nerves supplying one cervical or thoracic facet joint to treat pain attributed to that joint.
The physician uses a needle electrode to create a thermal lesion in the nerves supplying a cervical or thoracic facet joint, commonly for persistent axial neck or upper-back pain attributed to facet joints. Pain medicine physicians, anesthesiologists, and other appropriately trained specialists typically perform the procedure in an office procedure room or outpatient facility. Imaging guidance is part of the service, rather than a separately reported guidance service.
Report this code for the first treated cervical or thoracic facet joint; use 64634 for each additional joint in that region. Documentation should identify the treated levels and side, nerves targeted, imaging guidance, and the lesioning performed. The procedure has a 10-day global period, so related postoperative visits during 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 is paid in full and others at 50%. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

64633 billing questions
When should 64634 be reported with 64633?
Use 64633 for the first treated cervical or thoracic facet joint and 64634 for each additional joint in that region. The additional-joint code is not for another nerve or lesion at the same joint.
Does the code include imaging guidance?
Yes. Imaging guidance is included in the facet nerve lesioning service and is not separately reported as guidance for that procedure.
How is bilateral treatment reported?
For bilateral treatment, report modifier 50; CMS pays the bilateral procedure at 150%.
Does 64633 describe a diagnostic medial branch block?
No. It describes nerve lesioning. A diagnostic block, such as the cervical or thoracic facet nerve injection reported with 64490, is a different service.
What documentation supports reporting 64633?
Document the cervical or thoracic levels and side treated, the nerves targeted, imaging guidance, and the lesioning performed. Identify the first treated joint separately from any additional joints reported with 64634.
Are postoperative visits included?
Related postoperative visits during the 10-day global period are included in the procedure payment.
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.
