Nondisp fx of olecran pro w/o intartic extn l ulna, 7thR

This code describes a specific type of fracture involving the olecranon process of the left ulna. It indicates that the fracture is nondisplaced and does not extend into the joint space. Crucially, this code is used for a subsequent encounter where the initial injury was an open fracture (Type IIIA, IIIB, or IIIC) that has since developed malunion.

Use this code when documenting follow-up care for a patient who previously sustained a severe open fracture of the left olecranon, and the fracture has healed in an anatomically incorrect position (malunion). This would apply to encounters for ongoing management, assessment of the malunion, or planning for corrective procedures.

• Ensure the documentation clearly specifies "left ulna" and "olecranon process."
• Verify that the initial fracture was indeed an open fracture (Type IIIA, IIIB, or IIIC) and that malunion is explicitly documented.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
