Displaced avulsion fx left ilium, subs for fx w delay heal

This code signifies a fracture where a piece of the left ilium has been pulled away from the main bone by a tendon or ligament, and the fractured fragments are no longer in their normal anatomical alignment. This specific code is used when the patient is receiving follow-up care for this injury and the healing process is taking longer than expected.

Apply this code for patients presenting for subsequent treatment of a displaced avulsion fracture of the left ilium that is exhibiting delayed union. This includes follow-up appointments for cast changes, physical therapy, or imaging to monitor the slow healing of the fracture. It would not be used for the initial treatment of the fracture or if the fracture is healing normally.

• Ensure documentation clearly states "delayed healing" or "delayed union" for the specified fracture.
• Verify the fracture is specifically an "avulsion" type and located in the "left ilium."
• Confirm this is a "subsequent encounter" and not the initial treatment for the injury.
