Nerve block
About 64447: Single-injection femoral nerve block
Report this code for a single-injection femoral nerve block, with imaging guidance included when performed, for perioperative or other targeted analgesia.
This service is a single-injection block of the femoral nerve, commonly performed by an anesthesiologist or other qualified clinician for pain control around lower-extremity surgery, such as knee procedures. It may be performed in a preoperative area, procedure room, or facility operating setting. Imaging guidance, when used to place the injection, is included in the service. A catheter placed for continuous infusion is distinguished from this single-injection service.
Report the code when the documented target is the femoral nerve and the block is a single-injection technique. The record should identify the indication, side, nerve target, technique, and whether imaging was used. The CMS global period is zero days, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

64447 billing questions
When should 64447 be selected instead of 64448?
Use 64447 for a single-injection femoral nerve block. Use 64448 when a catheter is placed for continuous femoral nerve infusion.
Is imaging guidance separately reported?
Imaging guidance used to perform the femoral block is included in 64447. Do not report a separate guidance service for that work.
How is a bilateral femoral block reported?
Report the bilateral procedure with modifier 50. CMS pays the bilateral service at 150%.
Can a sciatic nerve block be reported on the same date?
A sciatic block may be reported separately when it is performed to address the sciatic nerve territory as well as the femoral nerve territory. The documentation should support each distinct nerve block.
What same-session payment reduction applies?
When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and applies the standard 50% reduction to the others.
Can an assistant or co-surgeon be reported for this service?
CMS does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
