Nondisp fx of ant wall of l acetab, subs for fx w nonunion

This code signifies a fracture of the front part of the left hip socket that has not shifted from its original position. The patient is in a later stage of care for this fracture, and the bone fragments have failed to heal together properly.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed nondisplaced anterior acetabular fracture that has developed into a nonunion. This would include scenarios such as ongoing management, evaluation for surgical intervention for the nonunion, or conservative treatment of the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the anterior wall of the left acetabulum.
• Verify the fracture was initially nondisplaced; if displaced, a different code would be required.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
