Unsp fx upper end left radius, subs for clos fx w nonunion

This code signifies a non-healing fracture located at the upper portion of the left radius, which was initially a closed injury. The patient is presenting for follow-up care or treatment related to this persistent fracture, indicating that the bone fragments have not united after a typical healing period.

Use this code for a patient presenting with a previously diagnosed closed fracture of the proximal left radius that has failed to heal. This would apply during subsequent visits for ongoing management, such as cast changes, physical therapy, or evaluation for surgical intervention due to the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the "left radius" and "upper end."
• Verify the initial fracture was closed; if open, a different code would be appropriate.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
