What 64462 covers
This add-on represents an additional thoracic paravertebral injection site using anesthetic and/or steroid, beyond the first site. Anesthesiologists and pain specialists commonly perform these blocks for perioperative pain control in thoracic surgery or for chest-wall analgesia. The service may be performed in an operating room, procedure suite, or other setting where regional anesthesia is provided.
Report 64462 only with the primary single-site thoracic paravertebral injection code, 64461; it is not a standalone service. Documentation should identify the thoracic paravertebral block, the additional injection site or sites, and the clinical purpose. CMS pays this add-on within the primary procedure’s global period. When the service is reported as bilateral with modifier 50, CMS pays it at 150%.
