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

This code signifies a displaced fracture of the olecranon process of the ulna, extending into the elbow joint, that has not healed properly (nonunion). This specific instance involves an open fracture, classified as Type I or II, and is being addressed in a subsequent encounter after initial treatment.

This code is appropriate for documenting follow-up care for a patient with a previously treated open olecranon fracture (Type I or II) where the fracture fragments are displaced, the fracture line enters the joint, and there is evidence of nonunion. This would apply when the patient is returning for further management of the nonunion, such as surgical intervention or continued conservative treatment.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for an open fracture Type I or II.
• Verify the fracture extends into the joint (intraarticular extension).
• Confirm the fracture is of the olecranon process of the ulna.
