Unspecified fracture of unspecified acetabulum, sequela

This code signifies a long-term complication or late effect resulting from an unspecified fracture of the acetabulum, the socket of the hip bone. It indicates that the specific type of acetabular fracture is not documented, and the sequela is currently being addressed.

Apply this code when a patient presents with a current condition or symptom that is a direct consequence of a previously sustained, but unspecified, acetabular fracture. This is appropriate for follow-up encounters addressing chronic pain, nonunion, malunion, or degenerative changes directly attributable to the past injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M16.1 for unilateral primary osteoarthritis of hip).
• Ensure documentation clearly links the current condition to a past acetabular fracture, even if the original fracture details are vague.
• Avoid using this code if the original acetabular fracture is still in the active healing phase; instead, use an acute fracture code with the appropriate seventh character.
