Unsp fx the lower end unsp rad, subs for clos fx w nonunion

This code signifies a fracture of the lower end of the radius, where the specific location within the lower end is not documented, and the side (left or right) is also unspecified. The fracture is closed, meaning the skin is intact, and it has failed to heal properly, requiring further treatment after the initial encounter.

Apply this code when a patient presents for follow-up care of a previously diagnosed, non-displaced or unspecified closed distal radial fracture that is demonstrating nonunion. This is appropriate for subsequent visits where the focus is on managing the ongoing healing complications of the fracture.

• Ensure documentation clearly states "nonunion" for a closed distal radial fracture.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
• Avoid using this code if the specific location or side of the fracture is documented; more specific codes exist.
