Displ commnt fx shaft of ulna, unsp arm, 7thJ

This code signifies a comminuted fracture of the ulna shaft that is displaced and involves an open wound classified as Type IIIA, IIIB, or IIIC. The patient is in a subsequent phase of care, specifically experiencing delayed healing of this complex injury.

This code is appropriate for documenting follow-up encounters for patients with a previously diagnosed displaced, comminuted, open ulna shaft fracture (Type IIIA, IIIB, or IIIC) who are exhibiting delayed healing. It should be used when the patient is still under active treatment for the fracture and its complications, but not for the initial acute injury.

• Ensure documentation clearly specifies "delayed healing" for this subsequent encounter.
• Verify the fracture is indeed comminuted and displaced, and the open wound type (IIIA, IIIB, or IIIC) is documented.
• Do not use for initial treatment or for nonunion/malunion, as those have separate codes.
