Disp fx of coronoid pro of l ulna, 7thC

This code signifies a break in the coronoid process, a small projection on the ulna bone in the forearm, where the bone fragments are no longer in their normal alignment. This specific injury involves an open wound, indicating that the bone has broken through the skin, and is classified as a severe open fracture (Type IIIA, IIIB, or IIIC).

Apply this code for initial encounters with patients presenting with a displaced coronoid process fracture of the left ulna that is openly exposed to the environment. This is appropriate for traumatic injuries where the skin integrity has been compromised, and the fracture is severe.

• Ensure documentation clearly specifies "displaced" and "left ulna" for accurate laterality and displacement.
• Verify the open fracture type (IIIA, IIIB, or IIIC) is explicitly stated in the medical record to support this specific code.
• This code is for the initial encounter; subsequent care will require different encounter codes.
