Disp fx of posterior wall of left acetabulum, init

This code signifies a break in the back portion of the left hip socket (acetabulum) where the bone fragments are no longer in their normal alignment. It specifically indicates that this is the first time the fracture is being treated and the skin over the fracture site remains intact.

Apply this code for patients presenting with a newly diagnosed, non-surgical (closed) fracture of the posterior wall of the left acetabulum that shows displacement on imaging. This is appropriate for the initial hospital stay or outpatient visit where the fracture is first evaluated and managed.

• Ensure documentation clearly specifies "left" acetabulum and "posterior wall" involvement.
• Verify imaging reports confirm displacement of the fracture fragments.
• Confirm the encounter is for the initial treatment of a closed fracture; subsequent encounters will require different seventh characters.
