Nondisp fx of posterior column of unsp acetabulum, init

This code signifies a fracture of the posterior column of the acetabulum (hip socket) that has not shifted out of alignment. The fracture specifically involves the ilioischial portion of the posterior column, indicating a break in the bone that forms the back part of the hip joint. This is an initial encounter for a closed fracture, meaning the skin is intact over the injury.

Use this code for patients presenting with a newly diagnosed, non-displaced fracture of the posterior column of the acetabulum, specifically involving the ilioischial part. This applies to initial treatment or evaluation of the injury. It is appropriate when imaging confirms the fracture's location and the absence of displacement.

• Ensure documentation specifies "nondisplaced" and "posterior column [ilioischial]" of the acetabulum.
• Verify this is the "initial encounter" for the fracture; subsequent care will use different encounter codes.
• Confirm the fracture is "closed" (no open wound communicating with the fracture site).
