Displaced transverse fx right acetab, subs for fx w nonunion

This code signifies a fracture of the right acetabulum, specifically involving the transverse portion, which has shifted out of its normal alignment. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

Use this code for patients presenting for subsequent treatment or evaluation of a previously diagnosed displaced transverse fracture of the right acetabulum that has not united. This includes situations where the patient is undergoing further surgical intervention, conservative management, or assessment for the nonunion.

• Ensure documentation clearly states "nonunion" for the transverse acetabular fracture.
• Verify the laterality is "right" and the fracture is explicitly described as "displaced" and "transverse."
• Confirm this is a "subsequent encounter" for the fracture, not the initial treatment.
