Oth fx upper end of unsp radius, subs for clos fx w nonunion

This code signifies a follow-up encounter for a patient with a closed fracture in the upper part of the radius bone, where the fracture has failed to heal properly (nonunion). The specific location within the upper radius is not precisely documented, and the skin over the fracture remains intact.

Use this code when documenting ongoing management, such as cast changes, physical therapy, or surgical planning, for a previously diagnosed closed upper radial fracture that has not united. This applies to situations where the patient is still receiving active treatment for the nonunion.

• Ensure documentation clearly states "nonunion" and that the fracture is closed.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the fracture is located in the "upper end" of the radius, even if the exact anatomical site (e.g., radial head, neck) is unspecified.
