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

This code signifies a fracture of the posterior wall of the left acetabulum that is displaced, meaning the bone fragments are not properly aligned. 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 when a patient presents for follow-up care of a previously diagnosed displaced posterior acetabular wall fracture on the left side, and the physician documents delayed healing. This would apply to scenarios such as repeat imaging showing incomplete callus formation or persistent pain beyond the typical healing timeframe for such a fracture.

• Ensure documentation specifies "left" acetabulum and "posterior wall."
• Confirm the fracture is explicitly described as "displaced."
• The "G" suffix requires documentation of delayed healing, not just routine follow-up.
