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

This code describes a fracture of the inner wall of the right hip socket that has shifted out of its normal alignment. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

This code is appropriate for subsequent encounters when a patient is receiving treatment for a previously diagnosed displaced fracture of the medial wall of the right acetabulum that has developed a nonunion. This includes situations where the patient is undergoing further evaluation, conservative management, or surgical intervention for the nonunion.

• Ensure documentation clearly specifies "displaced" and "nonunion" for the medial wall of the right acetabulum.
• Verify that the encounter is for follow-up care of the fracture, not the initial treatment.
• Always sequence this code after any acute fracture codes if the nonunion is a complication of a recently treated fracture.
