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

This code signifies a fracture where a fragment of bone has been pulled away by a tendon or ligament from an unspecified ischium, and the fracture fragments are not in their normal anatomical alignment. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing, meaning it is taking longer than expected to unite.

This code is appropriate for documenting follow-up encounters for patients with an avulsion fracture of the ischium that is not healing at the anticipated rate. It should be used when the physician specifically notes delayed union of the displaced avulsion fracture.

• Ensure documentation explicitly states "delayed healing" or "delayed union" for this specific fracture.
• Verify the fracture is indeed an avulsion type and that displacement is noted.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
