Disp fx of posterior wall of left acetabulum, sequela

This code signifies a long-term complication or residual effect stemming from a previously sustained fracture of the posterior wall of the left acetabulum. This could include chronic pain, nonunion, malunion, post-traumatic arthritis, or persistent functional impairment directly attributable to the original injury. The "sequela" designation indicates that the acute phase of the fracture has passed, and the patient is now experiencing a consequence of that past event.

Use this code when documenting a patient presenting with ongoing issues directly related to a prior displaced fracture of the posterior wall of the left acetabulum. This is appropriate for follow-up visits addressing chronic pain, limited range of motion, or other persistent problems after the initial fracture has healed or stabilized. It should be applied when the current encounter is for the management of the residual condition, not the initial injury.

• Always link this sequela code with an external cause code (V00-Y99) if the original injury's cause is known and relevant to the current encounter.
• Ensure documentation clearly states the connection between the current condition and the past acetabular fracture.
• Do not use this code for acute or active treatment of the initial fracture; use an acute fracture code (e.g., S32.422A, S32.422D, S32.422G, S32.422K, S32.422P) for those phases of care.
