Disp fx of posterior column of left acetabulum, sequela

This code signifies a healed or residual condition resulting from a displaced fracture of the posterior column of the left acetabulum. Specifically, it points to the ilioischial portion, indicating the fracture involved the weight-bearing dome and posterior wall of the hip socket. The "sequela" designation means the acute injury has resolved, but the patient continues to experience long-term effects or complications.

Use this code for patients presenting with ongoing symptoms, functional limitations, or anatomical changes directly attributable to a previously sustained and healed displaced posterior column acetabular fracture on the left side. This is appropriate for follow-up visits addressing chronic pain, arthritis, or instability stemming from the original injury, rather than the acute fracture itself.

• Always pair with an external cause code if the original injury mechanism is relevant for the sequela.
• Ensure documentation clearly supports the "sequela" designation, indicating the acute phase has passed.
• Do not use for the initial treatment of an acute fracture; this code is for long-term effects.
