What 64629 covers
This add-on captures treatment of an additional lumbar or sacral vertebral body during intraosseous basivertebral nerve ablation. Interventional pain physicians and spine specialists typically perform the procedure for selected patients with vertebrogenic low back pain. Imaging guidance used to perform the ablation is included in the service.
Report 64629 with the primary code 64628, which covers treatment of the first two vertebral bodies. Assign one unit for each additional body treated and document the treated vertebral levels, the clinical indication, and the procedure performed. CMS classifies 64629 as an add-on code: it is billed only with a primary procedure and paid within that procedure's global period.
