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

This code signifies a fracture where a piece of the left ischium (part of the pelvic bone) has been pulled away by a tendon or ligament, and the fractured fragment is no longer in its normal anatomical position. This specific code is used when the patient is receiving follow-up care for this injury, and the fracture is not healing at the expected rate.

Apply this code for patients presenting for ongoing treatment of a displaced avulsion fracture of the left ischium, such as cast changes, physical therapy, or follow-up imaging, when the healing process is prolonged. This indicates that the initial treatment has been rendered, but the fracture has not yet fully united.

• Ensure documentation clearly states "delayed healing" for the left ischium avulsion fracture.
• Verify the fracture is explicitly described as "displaced" and an "avulsion" type.
• Confirm this is a subsequent encounter for the fracture, not the initial treatment or a sequela.
