Pathological fracture, unspecified ulna and radius, sequela

This code signifies a bone fracture of both the ulna and radius that occurred due to an underlying disease process, rather than trauma, and is now a long-term complication or late effect. It indicates that the specific bone involved (ulna or radius) was not further specified in the documentation.

Apply this code for patients presenting with a current problem or condition that is a direct result of a previously healed pathological fracture of the unspecified ulna and radius. Documentation should clearly link the current issue (e.g., chronic pain, nonunion, malunion, functional limitation) to the prior pathological fracture.

• Requires a seventh character of 'S' for sequela, indicating a complication or late effect of the fracture.
• Always sequence this code after the code(s) describing the specific sequela being treated (e.g., M96.0 for pseudarthrosis).
• Ensure documentation specifies "pathological fracture" and not a traumatic fracture, and that the current encounter addresses a residual effect.
