Displaced avulsion fracture of unsp ischium, init for opn fx

This code signifies a fracture where a fragment of the ischium has been pulled away from the main bone by a tendon or ligament, and the fractured pieces are not in their normal anatomical alignment. It specifically indicates that the injury involves an open wound, exposing the bone to the outside environment.

This code is appropriate for the initial treatment of an avulsion fracture of an unspecified ischium that presents as an open fracture. This would include scenarios such as a patient presenting to the emergency department after a traumatic event where the ischium is avulsed and there is an associated open wound requiring surgical debridement and fracture management.

• Ensure documentation clearly specifies "open fracture" and "displaced" for accurate code assignment.
• Confirm this is the initial encounter for treatment of the fracture; subsequent encounters will require different seventh characters.
• If the specific ischium (e.g., right or left) is documented, a more specific code should be chosen.
