Disp fx of post column of r acetab, subs for fx w delay heal

This code signifies a fracture affecting the posterior column of the right acetabulum, specifically the ilioischial portion, which has become displaced. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed displaced posterior column acetabular fracture on the right side, and the healing process is not progressing as expected. This includes situations where the provider documents delayed union or nonunion of the fracture.

• Ensure documentation clearly specifies "displaced" and "posterior column [ilioischial]" of the right acetabulum.
• Verify the encounter is for subsequent care and that delayed healing is explicitly documented.
• Do not use for initial encounters or for fractures that are healing normally.
