Disp fx of olecran pro w intartic extn unsp ulna, 7thQ

This code describes a malunion of a previously treated open fracture (Type I or II) of the olecranon process, where the fracture extended into the elbow joint. The olecranon, the bony tip of the elbow, was displaced at the time of the initial injury, and the specific ulna (right or left) is not documented.

Use this code for a patient presenting with complications related to a healed or healing open olecranon fracture that has united in an unsatisfactory position, resulting in functional impairment or pain. This applies to follow-up encounters after the initial treatment of the open fracture, specifically when malunion is identified and being addressed.

• Ensure documentation clearly specifies "malunion" and a prior "open fracture type I or II" of the olecranon.
• Verify the fracture had intraarticular extension and was displaced initially.
• Do not use for nonunion, delayed union, or routine follow-up without malunion.
