What 64473 covers
This service covers a one-time injection of anesthetic medication, with or without steroid, into a fascial plane in the lower extremity to provide regional pain relief. Anesthesiologists, pain physicians, and other clinicians performing regional blocks may use it for perioperative analgesia or acute pain, such as pain associated with a hip fracture. Imaging guidance, when performed, is included in the block service.
Report 64473 for a unilateral, single-injection block; use the documented body site, side, medication, and technique to support the service. A catheter-based continuous infusion is a different service, not another unit of this injection code. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral performance, modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
