What 64636 covers

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.
