Nondisp fx of post wall of r acetab, subs for fx w nonunion

This code signifies a fracture located on the posterior wall of the right acetabulum that has not shifted from its original position. The patient is in a later stage of care, and the fracture has failed to heal properly, indicating a nonunion.

This code is appropriate for documenting follow-up encounters for patients with a previously diagnosed nondisplaced posterior wall acetabular fracture on the right side. It specifically applies when imaging or clinical assessment confirms that the fracture fragments have not united.

• Ensure documentation clearly states "nondisplaced" and specifies the "posterior wall" of the right acetabulum.
• Verify that the encounter is for follow-up care and that nonunion of the fracture is explicitly documented.
• Do not use this code for initial encounters or for fractures that are healing normally.
