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

This code describes a non-healing fracture of the olecranon process of the left ulna, which extends into the elbow joint. The fracture was initially an open fracture of Gustilo-Anderson type I or II, and the patient is now in a subsequent phase of care for this nonunion.

Apply this code when documenting ongoing treatment for a left olecranon nonunion that previously presented as an open fracture (Type I or II) and involves the articular surface. This is appropriate for follow-up visits, cast changes, or further surgical interventions addressing the nonunion.

• Ensure documentation specifies "nonunion" and a prior "open fracture type I or II" for the olecranon.
• Verify laterality (left ulna) and intraarticular extension are clearly documented.
• This code is for subsequent encounters, not the initial treatment of the acute fracture.
