Orthopedic Coding Alert

Question: One of our physicians performed a coracoclavicular ligamentous reconstruction (i.e., Weaver-Dunn procedure). I have been unable to locate a specific code for this procedure. Would the use of 23929 (unlisted procedure, shoulder) be appropriate?

Answer: Unfortunately, trying to locate the right CPT code by its eponym can be extremely frustrating because the CPT index only recognizes and includes a small number of them. For this reason, an orthopedic terminology manual can be the coders best friend. A Weaver and Dunn reconstruction is performed for a separation of the acromioclavicular joint. In this procedure, the coracoacromial ligament is transferred to the distal clavicle. Drill holes are made in the coracoid, and the distal clavicle and Mersilene tape is passed through the drill holes. The acromioclavicular joint is then reduced, and the tapes are tied in place. The coracoacromial ligament is then passed over the top of the distal clavicle and sutured in place, completing the reconstruction.

To find the correct CPT code, forget about the Weaver-Dunn eponym and remember what the surgeon is actually doingreducing a separation of the acromioclavicular joint. This will lead you to 23550 (open treatment of acromioclavicular joint, acute or chronic).
