Anterior disp fx of sternal end of unsp clavicle, init

This code signifies a break at the sternal (medial) end of the collarbone, where the fractured bone segment has shifted forward. The specific side (left or right) of the clavicle is not documented, and the injury is being treated for the first time as a closed fracture, meaning the skin is intact.

This code is appropriate for patients presenting with a newly diagnosed, non-displaced fracture of the medial clavicle where the laterality is not specified in the medical record. It applies to initial treatment encounters for such injuries that do not involve an open wound communicating with the fracture site.

• Ensure documentation clearly states "anterior displacement" and "sternal end" of the clavicle.
• If laterality (left or right) is specified, a more specific code should be chosen (e.g., S42.011A or S42.012A).
• Verify the encounter is for initial treatment and that the fracture is indeed closed.
