Nondisplaced avulsion fracture of unspecified ilium, sequela

This code describes a healed or residual effect of a nondisplaced avulsion fracture of an unspecified part of the ilium. An avulsion fracture occurs when a tendon or ligament pulls a small piece of bone away from the main bone. "Nondisplaced" indicates the bone fragments remain in their anatomical position, and "sequela" signifies a late effect or complication of the initial injury.

Use this code when documenting a patient presenting with ongoing symptoms or conditions directly attributable to a previously sustained, nondisplaced avulsion fracture of the ilium, where the acute phase of the injury has passed. This is appropriate for follow-up encounters addressing chronic pain, limited range of motion, or other long-term issues stemming from the original fracture.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic pain, malunion).
• Ensure documentation clearly links the current condition to the previous ilium avulsion fracture.
• Verify the fracture was indeed nondisplaced and that the encounter is for a sequela, not the initial acute injury or active healing phase.
