(A 58-year-old patient undergoes diagnostic facet joint injections.

Facet joint injections (medial branch blocks/intra-articular depending on code family) are coded byspinal regionandnumber of levels. Thoracic facet injections use64490for thefirst level,64491for thesecond level, and64492for thethird and each additional level(within the thoracic region). This case includesthree thoracic levels: T2–T3 (1st), T3–T4 (2nd), and T4–T5 (3rd). Because the injections arebilateral, you applymodifier -50to each of the level codes per the answer set’s style. Fluoroscopic guidance isbuilt intothese injection codes under current CPT rules, so you donotseparately report a fluoroscopy code (such as 76000). Options B and C are forlumbar/sacralfacet injection families, not thoracic. Option A incorrectly doubles units rather than using the correct third-level add-on coding structure. Therefore,64490-50, 64491-50, 64492-50is correct.
