Disp fx of head of left radius, subs for clos fx w nonunion

This code signifies a fracture of the radial head on the left arm that is no longer in its anatomical alignment. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care or treatment of this ongoing issue.

Apply this code when a patient with a previously diagnosed displaced left radial head fracture presents for management of a confirmed nonunion. This includes visits for cast changes, physical therapy, or surgical planning related to the nonunion, after initial treatment has been rendered.

• Ensure documentation clearly specifies "displaced" and "left radius head" for accurate laterality and fracture type.
• The "K" seventh character indicates a subsequent encounter for a closed fracture with nonunion, meaning initial treatment has concluded but healing is incomplete.
• Confirm the fracture is indeed a nonunion, not just delayed healing, as these have different seventh characters.
