Nondisp fx of posterior wall of unsp acetabulum, init

This code signifies a break in the posterior wall of the acetabulum, the socket portion of the hip joint, where the bone fragments remain in their normal anatomical alignment. The injury affects an unspecified side of the body and is being treated for the first time, without an open wound communicating with the fracture site.

Use this code for a patient presenting with a newly diagnosed, non-displaced fracture of the posterior acetabular wall, documented as a closed fracture. This is appropriate for the initial treatment encounter, such as emergency department visits or initial orthopedic consultations.

• Confirm documentation explicitly states "nondisplaced" and "posterior wall of acetabulum."
• Ensure the encounter is for the initial treatment of the fracture and that it is a closed fracture.
• If the side (left or right) is specified in the documentation, a more specific code should be used.
