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

This code signifies a displaced fracture of the olecranon process of the ulna that extends into the elbow joint. It specifically indicates a subsequent encounter for an open fracture (Type IIIA, IIIB, or IIIC) that has failed to heal properly, resulting in nonunion.

Use this code for follow-up care of a patient with a previously treated open olecranon fracture that has not united and involves displacement and intraarticular extension. This would apply to situations such as ongoing management, surgical intervention for nonunion, or evaluation of the nonunion status.

• Ensure documentation clearly specifies "subsequent encounter" and "nonunion" for an open fracture.
• Verify the fracture involves the olecranon process and has intraarticular extension.
• Confirm the original open fracture was classified as Type IIIA, IIIB, or IIIC.
