Displaced associated transv/post fx left acetabulum, sequela

This code signifies a chronic or late effect of a fracture involving the left acetabulum, specifically a displaced fracture pattern affecting both the transverse and posterior columns. The "sequela" indicator denotes that this code is used for complications or conditions arising as a direct result of the initial injury, even after the acute phase has passed.

This code is appropriate for documenting long-term complications such as malunion, nonunion, chronic pain, post-traumatic arthritis, or functional impairment directly attributable to a previously sustained displaced transverse-posterior fracture of the left acetabulum. It should be used when the patient is no longer in the active healing phase of the initial fracture.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., M16.4 for post-traumatic osteoarthritis).
• Ensure documentation clearly links the current condition to the prior acetabular fracture.
• Verify laterality (left) and the specific fracture pattern (displaced associated transverse-posterior) are explicitly stated in the medical record.
