Disp fx of post column of unsp acetab, 7thG

This code signifies a displaced fracture affecting the posterior column of the acetabulum, specifically the ilioischial portion, where the patient is in a subsequent phase of care and experiencing delayed healing. The fracture involves the weight-bearing dome and posterior wall of the hip socket, indicating a significant injury to the acetabulum.

This code is appropriate for encounters where a patient is receiving ongoing treatment for a previously diagnosed displaced posterior column acetabular fracture, and the healing process is not progressing as expected. It should be used when documentation explicitly states delayed union or delayed healing of this specific fracture type.

• Ensure documentation clearly specifies "displaced" and "posterior column [ilioischial]" for accurate code assignment.
• Verify that the encounter is for "subsequent care" and that "delayed healing" is explicitly noted by the provider.
• Do not use this code for initial encounters, routine follow-up without healing complications, or non-displaced fractures.
