Disp fx of lateral end unsp clavicle, subs for fx w nonunion

This code signifies a fracture of the outer portion of the collarbone, where the bone fragments are no longer in their normal alignment. Crucially, this specific code indicates that the fracture has failed to heal properly after an initial treatment, and the patient is presenting for ongoing management of this nonunion.

Use this code for follow-up encounters with a patient who has a previously diagnosed and treated displaced fracture of the lateral clavicle, and imaging or clinical assessment confirms that the fracture has not united. This applies when the patient is receiving continued care, such as further surgical intervention planning, cast changes, or physical therapy specifically addressing the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the "lateral end" of the clavicle.
• Verify that the encounter is for subsequent care of the nonunion, not the initial treatment or routine follow-up of a healing fracture.
• Always code laterality if specified in the documentation; "unspecified" should only be used when laterality is truly unknown.
