Nondisp fx of posterior wall of left acetabulum, init

This code signifies a break in the posterior (back) portion of the left acetabulum, the socket of the hip joint, where the bone fragments remain in their normal anatomical position. It indicates that the injury is new and the fracture has not broken through the skin.

Apply this code for patients presenting with a newly diagnosed, stable fracture of the posterior wall of the left acetabulum, confirmed by imaging, where the skin remains intact. This is appropriate for the initial treatment phase of such an injury.

• Ensure documentation specifies "nondisplaced" and "posterior wall" of the left acetabulum.
• Verify "initial encounter" for the treatment of a closed fracture.
• Distinguish from displaced fractures or those involving other acetabular walls.
