Displaced avulsion fx right ilium, subs for fx w nonunion

This code describes a situation where a piece of bone has been pulled away from the right ilium (the largest part of the hip bone) due to a strong ligament or tendon, and the fractured pieces are not in their normal alignment. Furthermore, this specific code indicates that the patient is receiving ongoing treatment for this fracture because it has failed to heal properly.

This code is appropriate for follow-up encounters when a patient with a previously diagnosed displaced avulsion fracture of the right ilium is being treated for a nonunion. This includes visits for continued conservative management, surgical planning for nonunion repair, or post-operative care related to the nonunion. It should be used after the initial treatment phase has concluded and the fracture has not united.

• Ensure documentation clearly specifies "nonunion" and "subsequent encounter" for this specific fracture.
• Always verify laterality (right ilium) is documented.
• Do not use this code for initial treatment of the fracture or for routine follow-up of a healing fracture.
