Pathological fracture, pelvis, sequela

This code signifies a bone fracture in the pelvis that occurred due to a pre-existing disease or condition, rather than significant trauma. It specifically indicates that the fracture is a long-term consequence or late effect of the underlying pathology.

Apply this code when documentation clearly states a pathological fracture of the pelvis and specifies that the encounter is for the sequela of this fracture. This is typically used for follow-up care, management of complications, or treatment of residual effects long after the initial fracture event.

• Always code the underlying disease responsible for the pathological fracture first, followed by this sequela code.
• Ensure documentation explicitly states "sequela" or "late effect" to justify the 7th character 'S'.
• Distinguish from acute pathological fractures (7th character A, D, G, K, P) or nonunion/malunion (7th character N, Q).
