What 64446 covers

This service covers delivery of anesthetic through a catheter placed at the sciatic nerve for continuous regional analgesia. Anesthesiologists and pain physicians commonly provide it around lower-extremity surgery, such as procedures involving the foot, ankle, or lower leg. Imaging guidance, when used, is included in the service. The catheter allows medication delivery to continue beyond a single injection.

Choose this code for a continuous sciatic catheter service rather than a single-injection sciatic block. Documentation should identify the nerve and side, catheter placement, the continuous infusion plan, and any imaging used. CMS assigns 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 others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
