What 64635 covers

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.

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.

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?

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.
