Nondisp avulsion fx right ilium, subs for fx w delay heal

This code signifies a fracture where a small piece of bone has been pulled away from the main bone by a tendon or ligament, specifically in the right ilium, without displacement of the bone fragment. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing, meaning it is not mending at the expected rate.

Apply this code when documenting follow-up care for a patient with a previously diagnosed avulsion fracture of the right ilium that was nondisplaced, and the physician notes indicate that the healing process is prolonged or slower than anticipated. This would be used after the initial treatment phase, during ongoing management of the fracture.

• Ensure documentation clearly specifies "nondisplaced" and "avulsion fracture" of the right ilium.
• Confirm the encounter is for subsequent care and the physician explicitly states "delayed healing."
• Do not use for initial encounters or for fractures that are healing normally.
