Displaced avulsion fracture of unspecified ischium, sequela

This code signifies a fracture where a piece of bone has been pulled away by a tendon or ligament, specifically affecting the ischium, one of the three bones that form the pelvis. The term "displaced" indicates that the bone fragments are not in their normal alignment, and "sequela" denotes that this is a late effect or complication of an earlier injury, not an acute fracture.

Apply this code for patients presenting with a chronic or healed avulsion fracture of the ischium that is still causing symptoms or requiring ongoing treatment. This is appropriate when the initial injury has passed the acute phase and the current encounter addresses long-term effects. It is used when documentation clearly specifies displacement and the avulsion nature of the fracture.

• Ensure documentation explicitly states "sequela" or indicates a healed/chronic fracture with ongoing issues.
• Verify the fracture is specifically of the ischium and described as an avulsion type.
• Confirm the displacement of the fracture fragments is noted in the clinical record.
