Using the CPT manual, select the appropriate CPT code for the following procedure.
Diagnosis: Nonunion of fracture of scaphoid carpal bone
Procedure: Repair with radial styloidectomy
Step 1: In the index, locate main term scaphoid, and under that locate sub term nonunion repair.
Step 2: Even when only one code is listed, always turn to the tabular list and review the description of the code and re-review the case to assure accuracy.
Step 3: The procedure was performed on the scaphoid carpal bone; the human body has two scaphoid carpal bones. However, the documentation above does not indicate which scaphoid carpal bone so a modifier for laterality cannot be appended. Do not assign a modifier for this case.
