About 64489: Bilateral TAP block with continuous infusion
Reports a bilateral transversus abdominis plane block with continuous catheter infusion for abdominal wall analgesia, commonly around abdominal surgery.
A transversus abdominis plane (TAP) block places local anesthetic in the fascial plane of the abdominal wall to provide analgesia. This code describes the block on both sides with continuous infusion through catheters; catheter insertion is included when performed. Anesthesia professionals commonly place these blocks around abdominal operations to support postoperative pain control, often in a hospital or surgical facility.
Choose this code when the service is bilateral and uses continuous catheter infusion, rather than a single injection. Document the block sites, bilateral service, catheter placement when performed, and the infusion plan. CMS assigns the code a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction. The code is priced as bilateral, so modifier 50 does not increase payment. CMS does not pay an assistant at surgery and does not permit co-surgeon or team-surgery payment for this code.
