Regional anesthesia
About 64448: Continuous femoral nerve catheter block
Reports a femoral nerve block delivered through a catheter for continuous infusion, commonly used to provide postoperative analgesia after knee or lower-extremity surgery.
This service places a catheter by the femoral nerve and delivers anesthetic continuously for regional pain control. Anesthesiologists and pain physicians commonly perform it around knee or other lower-extremity surgery, often in a hospital or ambulatory surgery setting. The service differs from a one-time femoral nerve injection because the catheter supports ongoing infusion; imaging guidance is included in the code when performed.
Report the service when the record supports femoral nerve targeting, catheter placement, and a continuous infusion plan. Document the indication, laterality, procedure details, and infusion regimen. The code has 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%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.

How does the 0-day global period affect same-day care?

What happens when other procedures are performed in the same session?
The highest-valued procedure is paid in full, and the other procedures are paid at 50% under the standard multiple procedure reduction.
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.
