Displaced avulsion fracture of left ilium, sequela

This code signifies a long-term complication or late effect stemming from a prior avulsion fracture of the left ilium, where the fractured bone fragment remains displaced. An avulsion fracture occurs when a tendon or ligament pulls a small piece of bone away from the main bone. The "sequela" indicates that the current encounter is for a problem directly resulting from the original injury, rather than the initial acute fracture.

This code is appropriate for encounters where a patient is being treated for ongoing issues, pain, or functional limitations directly attributable to a previously sustained and healed (or healing) displaced avulsion fracture of the left ilium. Examples include chronic pain, nonunion, malunion, or nerve impingement related to the displaced fragment. It should be used after the initial healing phase of the acute injury.

• Always use this code as a secondary diagnosis, with a primary code describing the specific sequela (e.g., chronic pain, nonunion).
• Ensure documentation clearly links the current condition to the prior avulsion fracture of the left ilium.
• Do not use this code for the initial treatment of an acute avulsion fracture; specific acute fracture codes would apply then.
