Displaced avulsion fracture of left ilium, init for opn fx

This code signifies a fracture where a fragment of bone has been pulled away from the main bone mass of the left ilium due to a strong ligament or tendon attachment. The fracture is displaced, meaning the bone fragments are not in their normal alignment, and it is an open fracture, indicating a break in the skin over the fracture site.

Apply this code for initial encounters when documenting an avulsion fracture of the left ilium that is clearly displaced and presents as an open fracture. This typically occurs following significant trauma where muscle contraction or ligamentous pull has detached a bone fragment.

• Ensure documentation specifies "left" ilium and "displaced" to support this specific code.
• The "B" in the seventh character indicates an initial encounter for an open fracture; verify the encounter type.
• Always code associated external cause codes (e.g., V00-Y99) to describe the circumstances of the injury.
