READER QUESTIONS:

Classify AC Joint as Intermediate

Question: If our surgeon injects a patient's AC joint, should we report 20610? We consider it a large joint because it's in the shoulder, but we aren't sure if that's accurate.

Answer: When the surgeon performs an injection to the AC (acromioclavicular) joint, you should report 20605 (Arthrocentesis, aspiration and/or injection; intermediate joint or bursa [e.g., temporomandibular, acromioclavicular, wrist, elbow or ankle, olecranon bursa]).

Many coders mistakenly believe that they should report 20610 (... major joint or bursa [e.g., shoulder, hip, knee joint, subacromial bursa]) for this type of injection, because the AC joint is between the shoulder and the clavicle, and the descriptor for 20610 references the shoulder. But 20605 specifically describes the acromioclavicular joint, so you should always report 20605 for AC joint injections.
