Disp fx of posterior column of right acetabulum, sequela

This code signifies a long-term complication or late effect stemming from a previously sustained displaced fracture of the posterior column of the right acetabulum. The posterior column, also known as the ilioischial column, is a critical weight-bearing structure of the hip joint. The "sequela" indicates that the initial acute injury has resolved, but the patient continues to experience residual effects directly attributable to that fracture.

This code is appropriate when a patient presents with ongoing symptoms or conditions (e.g., chronic pain, functional limitation, degenerative changes) that are a direct consequence of a healed or resolving displaced posterior column fracture of the right acetabulum. It should be used after the initial healing phase of the acute fracture has passed, and the patient is being treated for the lasting impact of the injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., M16.11 for unilateral primary osteoarthritis of the right hip).
• Ensure documentation clearly links the current condition to the previous acetabular fracture.
• Do not use this code for the initial acute fracture treatment; use the appropriate acute fracture code for that phase of care.
