About 24331: Elbow flexor-plasty with advancement
Reports advancement of the elbow flexor-pronator origin to improve elbow flexion, commonly for patients with substantial weakness of elbow flexion.
In this operation, the surgeon advances the flexor-pronator muscle origin on the upper arm to increase its leverage for elbow flexion. A classic use is a Steindler-type procedure for significant elbow-flexion weakness, including weakness after brachial plexus injury or polio. An orthopedic or hand surgeon typically performs the procedure in an operating room. The operative report should make clear that the flexor origin was advanced, rather than merely lengthened, released, or transferred to another site.
Report this code when the documented procedure includes advancement of the elbow flexor origin; the non-advancement flexor-plasty is a distinct sibling code. Documentation should identify the operative side, indication, structures advanced, and the work performed. CMS assigns a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be allowed; co-surgeon and team-surgery payment are not permitted.
