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

This code signifies a fracture of the posterior column of the left acetabulum, specifically the ilioischial portion, where the bone fragments are not in their normal anatomical alignment. The "G" suffix indicates that this is a subsequent encounter for the fracture, and the healing process is progressing slower than expected.

Use this code for a patient who has previously been treated for a displaced posterior column acetabular fracture on the left side, and during a follow-up visit, the physician documents delayed healing. This would apply to scenarios such as delayed union or nonunion, but the fracture is still actively being managed.

• Ensure documentation clearly specifies "displaced" and "posterior column [ilioischial]" of the left acetabulum.
• The "G" suffix is crucial and indicates delayed healing, not routine follow-up or initial treatment.
• Verify laterality (left) is explicitly stated in the medical record.
