Arthroscopic Excision of Distal Ulna

Question:

Our surgeon performed an arthroscopic excision of the distal ulna and wants to report the open procedure code. I am telling him that we must use an unlisted arthroscopic code. Can you advise us?

Answer:

You are correct. There is no CPT code for the arthroscopic excision of the distal ulna. He can use the open code as a comparable code for setting the fees and obtaining precertification or preauthorization. It would be considered incorrect to code to use anything other than an unlisted arthroscopy code.
