Path fx in oth disease, r radius, subs for fx w nonunion

This code signifies a right radius fracture that occurred due to an underlying medical condition, not from typical trauma. The fracture has failed to heal properly (nonunion), and the patient is receiving ongoing treatment for this complication. This indicates a chronic healing issue requiring continued medical intervention.

Apply this code when documentation specifies a right radius pathological fracture with nonunion, and the patient is presenting for follow-up care, cast changes, or ongoing management of the nonunion. Supporting documentation should clearly state the pathological nature of the fracture, the specific bone involved, and the nonunion status.

• Ensure documentation explicitly states "pathological fracture" and identifies the underlying disease if known (though not coded here).
• Verify the encounter type is "subsequent" for ongoing care, not initial treatment or sequela.
• Always sequence this code after the underlying disease causing the pathological fracture, if applicable and still active.
