Bundle Biopsy Into Arthrotomy

Question: Encounter notes indicate that the orthopedic surgeon performed a right shoulder arthrotomy with biopsy. What code(s) represent this surgery? Can I report the biopsy separately from the arthrotomy?

Answer: No, you cannot report the biopsy separately. CPT® code descriptors for this procedure all read “including biopsy” or “with or without biopsy,” so there’s no opportunity to code biopsy separately. You will, however, need some more information on the arthrotomy specifics.

Do this: Go back and check the notes, and try to find out which joint the surgeon treated: glenohumeral, acromioclavicular, or sternoclavicular. Then, choose from one of the following codes for the arthrotomy:

  • 23100 (Arthrotomy, glenohumeral joint, including biopsy)
  • 23101 (Arthrotomy, acromioclavicular joint or sternoclavicular joint, including biopsy and/or excision of torn cartilage)
  • 23105 (Arthrotomy; glenohumeral joint, with synovectomy, with or without biopsy)
  •  23106 (Arthrotomy; sternoclavicular joint, with synovectomy, with or without biopsy)

Also, append modifier RT (Right side) to the arthrotomy code to indicate laterality.
