Displaced transverse fracture of right acetabulum, sequela

This code signifies a long-term complication or late effect stemming from a previously sustained displaced fracture of the transverse portion of the right acetabulum. It indicates that the initial injury has healed, but the patient is now experiencing residual issues directly attributable to that specific fracture.

This code is appropriate when documenting conditions such as chronic pain, nonunion, malunion, post-traumatic arthritis, or functional limitations that are a direct consequence of a healed displaced transverse fracture of the right acetabulum. It should be used for encounters where the primary focus is the management of these sequelae, not the initial acute injury.

• Always use 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 previous acetabular fracture.
• Do not use this code for the initial treatment of the acute fracture or for follow-up care during the healing phase.
