About 64463: Thoracic paravertebral catheter infusion block
Reports a thoracic paravertebral block using a catheter for continuous anesthetic infusion, commonly to provide perioperative pain control after chest or breast surgery.
Code 64463 reports a thoracic paravertebral block performed with a catheter for continuous anesthetic infusion. The catheter delivers medication near the thoracic spinal nerves beside the vertebral column. Anesthesiologists and pain medicine physicians commonly perform the block for perioperative analgesia, including after thoracotomy or breast surgery, in an operating room or other procedural setting. Imaging guidance, when used for the block, is included.
Select this code for the continuous catheter technique rather than a single-injection thoracic block. Document the thoracic site, laterality, catheter technique, and plan for continuous infusion. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
