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

This code signifies a fracture of the inner wall of the left hip socket that has not shifted out of alignment. Importantly, the fracture has failed to heal properly, and the patient is presenting for follow-up care related to this nonunion.

This code is appropriate for documenting a patient encounter where the primary focus is the ongoing management of a previously diagnosed, nondisplaced fracture of the medial wall of the left acetabulum that has progressed to nonunion. This would include visits for evaluation, treatment planning, or monitoring of the nonunion.

• Ensure documentation clearly states "nondisplaced" and specifies the "medial wall" of the acetabulum.
• Confirm the encounter is for a "subsequent encounter" and explicitly mentions "nonunion" of the fracture.
• Always sequence this code after any acute injury codes if the patient is still being treated for the initial injury alongside the nonunion.
