Disp fx of posterior wall of left acetab, init for opn fx

This code signifies a break in the posterior wall of the left hip socket (acetabulum) where the bone fragments are no longer in their normal alignment. This specific injury is an open fracture, meaning there is a break in the skin communicating with the fracture site, and it is the initial treatment encounter.

Apply this code for patients presenting with a newly diagnosed, displaced, open fracture of the posterior wall of the left acetabulum. This is typically seen following high-impact trauma, such as motor vehicle accidents or falls from significant heights. It should be used for the initial surgical or non-surgical management of the fracture.

• Ensure documentation clearly specifies "displaced" and "posterior wall" for the left acetabulum.
• Verify the fracture is explicitly documented as "open" to differentiate from closed fractures.
• This "B" seventh character indicates the initial encounter for active treatment of the fracture.
