Disp fx of med wall of unsp acetab, subs for fx w nonunion

This code signifies a fracture of the inner wall of the hip socket that has shifted out of alignment and is not healing properly. This specific code is used when the patient is seen for follow-up care related to this non-healing fracture.

Apply this code for patients presenting for ongoing management of a previously diagnosed, displaced medial acetabular fracture that has failed to unite. This includes encounters for evaluation, treatment planning, or interventions for the nonunion, such as bone grafting or revision surgery.

• Requires a seventh character "K" indicating subsequent encounter for fracture with nonunion.
• Ensure documentation clearly specifies "displaced" and "medial wall" of the acetabulum.
• Do not use for initial encounters or for fractures that are healing normally.
