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.

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.

64445 billing questions

How does 64445 differ from 64446?

Is imaging guidance separately reportable?

Imaging guidance, when performed for this block, is included in 64445. Do not separately report guidance for the same block.

CMS identifies 64445 as a bilateral procedure; modifier 50 is paid at 150%. Document the block on each side.

What happens when 64445 is performed with another procedure?

When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and the others at 50%.

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for 64445. 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 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.
