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

This code describes a displaced fracture of the olecranon process, which is the bony prominence at the tip of the elbow, without the fracture extending into the joint. It specifically indicates that the patient is in a subsequent phase of care for a severe open fracture (Type IIIA, IIIB, or IIIC) that has failed to heal properly, resulting in a nonunion.

Use this code for a patient presenting with a previously diagnosed severe open olecranon fracture that is not healing as expected, and the fracture is displaced but does not involve the joint. This code is appropriate when documentation confirms a nonunion of an unspecified ulna's olecranon process following an initial open fracture of a significant nature.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for the fracture.
• Verify the fracture is of the olecranon process and explicitly states "without intraarticular extension."
• Confirm the original open fracture was classified as Type IIIA, IIIB, or IIIC.
