Oth fx upr end r ulna, subs for opn fx type I/2 w delay heal

This code signifies a fracture of the upper portion of the right ulna, excluding the olecranon or coronoid process, that was initially an open fracture classified as Type I or II. The patient is currently in a phase of delayed healing, meaning the fracture is not progressing to union at the expected rate.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed open Type I or II fracture of the upper right ulna (excluding olecranon/coronoid) is experiencing delayed healing. It would be used when the physician documents the fracture's delayed progression towards union.

• Ensure documentation explicitly states "delayed healing" for the fracture.
• Verify the initial fracture was an open Type I or II and located in the upper ulna (excluding olecranon/coronoid).
• This code is for subsequent encounters, not the initial treatment of the fracture.
