Pathological fracture, other site, sequela

This code signifies a pathological fracture occurring in an anatomical location other than those specifically classified elsewhere, where the fracture is a late effect or complication of a previous injury or disease. It indicates that the fracture is not acute but rather a residual condition.

Apply this code when documentation clearly states a pathological fracture at an unspecified or "other" site, and explicitly identifies it as a sequela. This is appropriate for conditions like non-union, malunion, or chronic pain directly attributable to a past pathological fracture. Documentation should specify the "other site" if known, and confirm the sequela status.

• Ensure the documentation explicitly states "sequela" or "late effect" to justify the seventh character 'S'.
• Do not use for acute pathological fractures; those require the appropriate seventh character for initial, subsequent, or routine healing.
• Always attempt to identify a more specific anatomical site code if available, as "other site" should be a last resort.
