Oth extrartic fx low end l rad, subs for clos fx w nonunion

This code signifies a fracture of the lower end of the left radius, located outside the joint capsule, that has failed to heal properly. The patient is in a subsequent phase of care for this non-union, and the fracture remains closed (skin intact).

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed extraarticular fracture of the distal left radius that has not united. This includes situations where further interventions, such as bone grafting or revision surgery, are being considered or performed due to the nonunion. It would also be used for ongoing management and monitoring of the nonunion.

• Always confirm the fracture location is extraarticular and on the left radius.
• Ensure documentation clearly states "nonunion" and that the encounter is subsequent to the initial treatment.
• Verify the fracture is closed; open fractures would require a different seventh character.
