Unsp fx upper end unsp ulna, subs for clos fx w delay heal

This code signifies a fracture of the upper portion of the ulna where the specific location (e.g., olecranon, coronoid process) is not documented. It indicates that the patient is in a subsequent phase of care for a closed fracture that is experiencing delayed healing.

Apply this code when a patient presents for follow-up care of an ulnar fracture, and the documentation specifies delayed healing of a closed fracture, but lacks detail regarding the precise anatomical site of the fracture within the upper ulna. This is appropriate when the initial injury was not an open fracture.

• Ensure documentation clearly states "delayed healing" for a closed fracture.
• Only use this code when the specific part of the upper ulna fractured is not identified.
• Verify that the encounter is for follow-up care, not the initial treatment.
