Orthopedic Coding Alert

Question: Which code should we report for a reverse total shoulder arthroplasty?

Indiana Subscriber Answer: You should report 23472 (Arthroplasty, glenohumeral joint; total shoulder [glenoid and proximal humeral replacement (e.g., total shoulder)]) for the reverse total shoulder arthroplasty.
 
If the surgeon can provide sufficient supporting documentation and thinks his work on the arthroplasty went over and above what the total shoulder replacement normally requires, ask him whether he thinks modifier 22 (Unusual procedural services) is warranted. If so, you can report 23472-22 to denote the additional work the surgeon performed.
 
Include the operative report and a letter with   your claim, in which the surgeon should explain that  he performed advanced rotator cuff arthroplasty  using a reverse total shoulder replacement.
 
Have the physician explain the patient's condition and discuss why the procedure was more complicated than a standard arthroplasty.
