Nondisp commnt fx shaft of ulna, r arm, 7thM

This code signifies a comminuted fracture of the shaft of the right ulna that has not displaced, meaning the bone fragments remain in their anatomical alignment. The fracture is an open type I or II, indicating a break in the skin with minimal to moderate soft tissue damage, and it has progressed to a nonunion, where the bone has failed to heal after a reasonable period.

This code is appropriate for follow-up encounters for a patient with a previously diagnosed right ulnar shaft fracture that was initially open (type I or II) and is now complicated by nonunion. It would be used when the patient is receiving ongoing treatment for this specific nonunion, such as surgical intervention, bone grafting, or other management strategies.

• Ensure documentation clearly specifies "nondisplaced" and "comminuted" for the ulnar shaft fracture.
• Verify the original fracture was an "open type I or II" and that "nonunion" is explicitly documented as the current healing status.
• This code is for subsequent encounters; an initial encounter for this specific nonunion would use a different seventh character.
