CPT code 64474: Fascial plane block, unilateral continuous infusion2026 Medicare rate & RVUs

Medicare pays $266.21 for 64474 nationally in the office and $68.14 in a hospital or facility. Local office rates run $234.62–$361.25.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 64474 covers

This code describes a lower-extremity fascial plane block on one side that delivers anesthetic through a catheter for continuous infusion. Anesthesiologists and pain specialists may use this approach for regional analgesia around hip or thigh procedures; examples of fascial plane techniques in this area include fascia iliaca and PENG blocks. The record should identify the side and block site, document catheter placement and the continuous infusion approach, and explain the clinical purpose. Document imaging guidance when used.

Choose this code for the continuous-infusion service, rather than the unilateral injection service represented by 64473. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 identifies bilateral performance and payment is at 150%. Medicare does not pay an assistant at surgery for this procedure; co-surgeons and team surgery are not permitted.
