Nondisp fx of med wl of unsp acetab, subs for fx w nonunion

This code signifies a previously diagnosed fracture of the inner wall of the hip socket that was initially in good alignment but has failed to heal properly. The patient is presenting for ongoing treatment of this unhealed fracture.

Use this code when documenting a patient encounter for a non-displaced medial acetabular wall fracture that has not united, and the patient is receiving follow-up care, such as cast changes, physical therapy, or preparation for revision surgery. This applies after the initial treatment phase.

• Ensure documentation clearly states "nonunion" and specifies the "medial wall" of the acetabulum.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Confirm the fracture was initially non-displaced to align with this specific code.
