What 64492 covers
This service covers the third or a further cervical or thoracic paravertebral facet-joint level treated with diagnostic or therapeutic medication, or a block of the nerve supplying that joint. An interventional pain physician, anesthesiologist, or other qualified clinician typically performs it with fluoroscopic or CT guidance for evaluation or treatment of axial neck or upper-back pain. The code is for facet joints or their innervating nerves, not an epidural injection.
Report 64492 only as an add-on in the cervical/thoracic level series: 64490 identifies the first level, 64491 the second, and 64492 the third or further level. Document the spinal region, each treated level, side, target, indication, and image-guided technique. CMS pays this add-on within the primary procedure’s global period; it is not submitted alone. For bilateral procedures, CMS pays modifier 50 at 150%.
