Unsp fx shaft of unsp radius, subs for clos fx w nonunion

This code signifies a fracture of the main part of the radius bone in the forearm, where the specific location of the break is not documented. It indicates that the fracture has not healed properly (nonunion) and the patient is presenting for follow-up care after initial treatment, with the skin over the fracture remaining intact.

Apply this code when a patient is seen for ongoing management of a previously treated, closed radial shaft fracture that has failed to unite. This would include scenarios where surgical intervention for nonunion is being planned or conservative management for nonunion is continuing, and the documentation does not specify the exact part of the radial shaft involved.

• Ensure documentation clearly states "nonunion" and that it's a subsequent encounter for a closed fracture.
• Only use this code when the specific site on the radial shaft (e.g., proximal, midshaft, distal) is not documented.
• Always check for more specific codes if the laterality (left/right) or a more precise location of the fracture is known.
