What 24330 covers

Elbow flexor-plasty surgically repositions or reshapes the flexor mechanism to improve the patient’s ability to bend the elbow. A classic example is the Steindler procedure, used for substantial loss of active elbow flexion, including weakness following a brachial plexus injury. An orthopedic or hand surgeon typically performs the operation in a surgical setting. The operative technique distinguishes this procedure from flexor-plasty that includes advancement.

Report 24330 when the documented operation is elbow flexor-plasty without the advancement specified by its sibling code 24331. The operative report should identify the procedure and the structures addressed; the clinical record should support the functional deficit and surgical indication. The day-before preoperative visit and 90 days of related postoperative care are included in the 90-day global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeons and team surgery are not permitted.

How to choose

24331Elbow flexor-plasty
Both describe elbow flexor-plasty. Use 24331 when advancement is part of the operation; 24330 describes flexor-plasty without that advancement.
24301Tendon transfer
24301 describes a muscle or tendon transfer in the upper arm or elbow. Choose 24330 for an elbow flexor-plasty, such as a Steindler procedure.
24305Tendon lengthening
24305 reports tendon lengthening at the upper arm or elbow. It is not the code for a flexor-plasty intended to improve elbow flexion.
