Nondisp fx of lateral end l clavicle, subs for fx w nonunion

This code signifies a fracture of the outer portion of the left collarbone that has not shifted from its normal anatomical position. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and the "nonunion" specifies that the bone fragments have failed to heal together after a reasonable period.

Apply this code when documenting ongoing treatment for a patient whose left lateral clavicle fracture has not united. This would include scenarios such as surgical intervention for nonunion, casting or bracing adjustments, or physical therapy aimed at promoting healing in a nonunion.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the fracture is specifically of the "lateral end" and on the "left" side.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
