Disp fx of ant wall of unsp acetab, subs for fx w nonunion

This code signifies a displaced fracture of the anterior wall of the acetabulum that has not healed properly, specifically in a nonunion state. It indicates a subsequent encounter for ongoing management of this specific type of pelvic fracture complication. The "unspecified acetabulum" implies the laterality (left or right) is not documented.

Utilize this code for patients presenting for follow-up care of a previously diagnosed displaced anterior acetabular wall fracture where imaging confirms nonunion. This is appropriate when the patient is actively receiving treatment or monitoring for the nonunion, such as prior to revision surgery or during conservative management.

• Ensure documentation clearly specifies "nonunion" for the fracture healing status.
• Verify the fracture is of the anterior wall of the acetabulum; other acetabular fracture types have different codes.
• Confirm this is a subsequent encounter, not an initial treatment for the nonunion.
