Disp fx of ant wall of right acetab, subs for fx w nonunion

This code signifies a right acetabular fracture involving the anterior wall that is displaced from its normal anatomical position. The patient is in a subsequent phase of care, and the fracture has failed to heal properly, indicating a nonunion.

This code is appropriate for documenting ongoing treatment of a right anterior acetabular wall fracture that has not united. It should be used when a patient presents for follow-up care, surgical intervention for nonunion, or conservative management of a known nonunion after the initial acute treatment phase.

• Always confirm laterality (right) and the specific acetabular wall involved (anterior).
• Ensure documentation clearly states "nonunion" and that this is a subsequent encounter.
• Pair with external cause codes (V, W, X, Y) if the cause of the fracture is known and documented.
