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

This code signifies a fracture where a piece of bone has been pulled away from the main bone by a tendon or ligament, specifically affecting an unspecified part of the ilium. The fracture is displaced, meaning the bone fragments are not in their normal alignment. This particular code is used during the healing phase when the fracture is not progressing as expected.

Apply this code for follow-up encounters with patients who have a previously diagnosed displaced avulsion fracture of an unspecified ilium, and the physician documents that the healing process is delayed. This would be appropriate when the patient is still receiving active treatment for the fracture, but the expected timeline for union has been exceeded.

• Ensure documentation explicitly states "delayed healing" for this subsequent encounter.
• Confirm the fracture is specifically an avulsion type and is displaced.
• Do not use for initial encounters or for fractures that are healing normally.
