Displ avulsion fx right ischium, subs for fx w routn heal

This code describes a follow-up visit for a patient who sustained a fracture where a piece of bone was pulled away by a tendon or ligament from the right ischium. The fracture fragment is not in its anatomical position, and the bone is currently healing as expected without complications.

Use this code for subsequent encounters when a patient with a previously diagnosed displaced avulsion fracture of the right ischium is undergoing routine follow-up care. This applies when the fracture is progressing through its normal healing stages and no complications or delayed healing are noted.

• Ensure documentation specifies "subsequent encounter" and "routine healing."
• Confirm the fracture is of the right ischium and is explicitly described as "displaced" and an "avulsion" type.
• Do not use for initial treatment or if delayed healing, nonunion, or malunion are present.
