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

This code signifies a previously treated fracture of the olecranon process of the ulna that extended into the elbow joint, which has now healed improperly (malunion). The fracture was displaced, meaning the bone fragments were out of alignment, and the specific ulna (left or right) is not documented.

Use this code for follow-up encounters where a patient is being managed for a malunion of a closed intraarticular olecranon fracture of an unspecified ulna. This applies when the initial fracture treatment has concluded, and the current focus is on addressing the suboptimal healing.

• Ensure documentation clearly states "malunion" and specifies a "subsequent encounter."
• Verify that the fracture was intraarticular and involved the olecranon process.
• If the laterality (left or right ulna) is documented, a more specific code should be used.
