Disp fx of post wl of unsp acetab, subs for fx w routn heal

This code signifies a displaced fracture of the posterior wall of the acetabulum, the socket portion of the hip joint. It specifically indicates that the patient is in a subsequent encounter phase, and the fracture is healing routinely without complications.

This code is appropriate for follow-up visits where a patient is recovering from a posterior acetabular wall fracture and the physician notes normal healing progression. It applies when the fracture is displaced and the encounter is not for initial treatment or for a nonunion/malunion.

• Ensure the documentation specifies "subsequent encounter" and "routine healing."
• Verify the fracture location is the posterior wall of the acetabulum.
• Confirm the fracture is described as "displaced."
