Peripheral nerve block
About 64449: Lumbar plexus anesthetic injection
Reports injection of anesthetic and/or steroid at the lumbar plexus for regional anesthesia, perioperative analgesia, or selected pain treatment.
This service places anesthetic and/or steroid near the lumbar plexus to interrupt nerve signals from the lower extremity. Anesthesiologists and pain physicians commonly perform it in an operating room, procedure suite, or other setting where regional blocks are provided. A lumbar plexus block may support anesthesia or postoperative pain control for hip or femur procedures, or be used in selected pain-treatment plans.
Report the code when the documented target is the lumbar plexus, rather than an individual femoral or sciatic nerve. The record should identify the indication, laterality, target, and medication injected. This is a minor procedure with a 0-day global period, so same-day preoperative and postoperative care is included. When performed in the same session with other procedures, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. For bilateral service, modifier 50 is paid at 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.

Use this code when the documented injection targets the lumbar plexus. A block directed at the femoral nerve is reported with the femoral nerve code instead.
Does the code include same-day preoperative and postoperative care?
Yes. It has a 0-day global period, and same-day preoperative and postoperative care is included.
How is bilateral lumbar plexus injection reported?
Report bilateral service with modifier 50. CMS pays the bilateral procedure at 150%.
What happens when this is performed with another procedure in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
Can an assistant or co-surgeon be reported for this procedure?
Assistant-at-surgery services are not paid. Co-surgeons and team surgery are not permitted.
