About 64636: Additional lumbar or sacral facet nerve ablation
Reports neurolytic treatment of each additional lumbar or sacral facet joint, typically during radiofrequency ablation for facet-mediated low back pain.
This add-on code represents neurolytic treatment of another lumbar or sacral facet joint after the first joint is treated. In a common radiofrequency procedure, an interventional pain physician uses imaging to guide treatment of the medial branch nerves that supply the targeted facet joint. The procedure is used for selected patients with chronic axial low back pain attributed to lumbar or sacral facet joints, often after diagnostic medial branch blocks. Imaging guidance is included in the procedure.
Report 64636 for each additional lumbar or sacral facet joint treated, alongside 64635 for the first joint. The procedure note should identify the treated joint levels, laterality, nerves targeted, and imaging guidance. CMS classifies 64636 as an add-on code: it must be billed with its primary procedure and is paid within that procedure's global period. For a bilateral procedure reported with modifier 50, CMS pays 150% of the applicable amount.

64636 billing questions
When should 64636 be reported instead of 64635?
Use 64635 for the first lumbar or sacral facet joint treated. Report 64636 for each additional joint treated in the same procedure.
Is 64636 reported per nerve or per facet joint?
It is reported for each additional facet joint, not for each individual medial branch nerve treated to reach that joint.
Can 64636 be billed by itself?
No. It is an add-on code and must be billed with the primary procedure, 64635, for the first lumbar or sacral facet joint.
Can imaging guidance be billed separately?
Imaging guidance for the facet nerve destruction procedure is included in the code. The documentation should identify the guidance used.
How is bilateral treatment reported?
For a bilateral procedure reported with modifier 50, CMS pays 150% of the applicable amount.
What documentation supports multiple units of 64636?
Document each additional lumbar or sacral facet joint treated, its laterality, the nerves targeted, and the imaging guidance used.
