Displaced avulsion fracture of unsp ilium, init for clos fx

This code signifies a fracture where a fragment of bone has been pulled away from the main bone structure of the ilium due to the forceful contraction of a muscle or ligament. The fracture is displaced, meaning the bone fragments are not in their normal alignment, and the specific location on the ilium is not documented.

Apply this code for initial encounters with patients presenting with a newly diagnosed, displaced avulsion fracture of an unspecified part of the ilium. This is appropriate when the medical record clearly indicates an avulsion mechanism and displacement, but the precise anatomical location on the ilium (e.g., anterior superior iliac spine, anterior inferior iliac spine) is not specified.

• Ensure documentation explicitly states "avulsion fracture" and "displaced."
• Only use this code when the specific site of the avulsion on the ilium is not documented; otherwise, a more specific code should be chosen.
• The "A" suffix indicates an initial encounter for active treatment of the fracture.
