Disp fx of olecran pro w/o intartic extn l ulna, 7thM

This code describes a specific type of fracture involving the olecranon process of the left ulna, which is displaced but does not extend into the elbow joint. The fracture was initially an open fracture (Type I or II) and is now in a subsequent phase of treatment where the bone has failed to heal properly (nonunion).

This code is used when documenting follow-up care for a patient with a previously treated open olecranon fracture of the left ulna that has not united. This includes situations where the patient is undergoing further evaluation, conservative management, or surgical intervention for the nonunion.

• Ensure documentation specifies "left" ulna and "displaced" olecranon fracture without intraarticular extension.
• Confirm the initial injury was an "open fracture type I or II" and that "nonunion" is explicitly stated for the subsequent encounter.
• Do not use this code for initial encounters, malunion, or closed fractures.
