Nondisp fx of olecran pro w intartic extn l ulna, 7thN

This code describes a specific type of left elbow fracture involving the olecranon process, which extends into the joint but is not displaced. The "N" suffix indicates that this is 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 encounters where a patient is being treated for a previously sustained open, intra-articular olecranon fracture of the left ulna that has not united. This would apply when the patient is undergoing ongoing management for the nonunion, such as further surgical intervention, casting, or other conservative treatments aimed at promoting healing.

• Ensure the fracture is specifically of the left ulna's olecranon process with intra-articular extension.
• Verify that the original injury was an open fracture classified as Type IIIA, IIIB, or IIIC.
• Confirm that the current encounter addresses the nonunion of this specific fracture.
