What 64445 covers
This service is a single-injection block targeting the sciatic nerve, using an anesthetic agent and/or steroid. Anesthesiologists and pain physicians commonly perform it for perioperative anesthesia or postoperative pain relief, including for procedures involving the lower extremity. It may be performed in a facility or office setting. Image guidance, when used, is included in the service.
Select this code for a single injection at the sciatic nerve; use the continuous-infusion catheter code when that is the service performed. Document the indication, nerve targeted, laterality, medication, technique, and whether a catheter was placed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures 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.
