Nondisp fx of posterior wall of unsp acetabulum, sequela

This code describes a long-term complication or late effect stemming from a fracture of the posterior wall of the acetabulum that was not displaced. The acetabulum is the socket of the hip joint, and a posterior wall fracture typically results from a direct blow to the knee with the hip flexed. The "sequela" indicates that the original fracture has healed, but the patient is still experiencing residual problems or conditions directly related to that past injury.

Use this code when documenting a patient presenting with ongoing issues, such as chronic pain, stiffness, or functional limitations, that are directly attributable to a previously sustained and healed nondisplaced posterior acetabular wall fracture. This code is appropriate for follow-up encounters addressing these persistent problems, not for the initial acute injury.

• Always use this code as a secondary diagnosis, following a code that describes the specific sequela (e.g., chronic pain, osteoarthritis).
• Ensure documentation clearly links the current condition to the past acetabular fracture.
• Verify that the fracture was explicitly documented as "nondisplaced" and involved the "posterior wall" of the acetabulum.
