Displaced transverse fracture of unsp acetabulum, sequela

This code signifies a long-term complication or late effect stemming from a previously displaced fracture of the transverse portion of the acetabulum, where the specific side (left or right) is not documented. It indicates that the initial injury has healed, but the patient is still experiencing residual problems directly attributable to that fracture.

Apply this code when a patient presents with ongoing issues such as chronic pain, malunion, nonunion, degenerative changes, or functional limitations that are a direct consequence of a past displaced transverse acetabular fracture. This code is appropriate when the initial fracture treatment is complete, and the current encounter addresses the sequelae.

• Requires a seventh character "S" to denote sequela, indicating a late effect.
• Always sequence this code after the code(s) describing the specific nature of the sequela (e.g., M84.28 for nonunion, M16.x for osteoarthritis).
• Ensure documentation clearly links the current condition to the previous displaced transverse acetabular fracture, and that the side is unspecified.
