What 64448 covers
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.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

64448 billing questions
How does this differ from 64447?
64448 is for a femoral nerve catheter with continuous infusion. 64447 is the corresponding femoral nerve service for a single injection rather than a continuous catheter infusion.
Is catheter placement separately reported?
Catheter placement is part of this service. The documentation should show placement and the plan for continuous infusion.
Can modifier 50 be used for bilateral treatment?
CMS identifies this as a bilateral procedure; modifier 50 is paid at 150%. Document treatment on both sides.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the 0-day global period.
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 indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
