Anterior subluxation of left sternoclavicular joint, init

This code signifies a partial dislocation of the left sternoclavicular (SC) joint, where the clavicle has moved forward relative to the sternum. The joint surfaces are still in partial contact, but their alignment is disrupted. This injury typically results from trauma to the shoulder or upper chest.

This code is appropriate for the initial encounter of a patient presenting with a newly diagnosed anterior subluxation of the left sternoclavicular joint. This includes the first visit for evaluation, diagnosis, and initiation of treatment for this specific injury.

• Ensure documentation specifies "anterior" subluxation and "left" side.
• Confirm this is the patient's initial visit for this specific injury, not a follow-up.
• Distinguish from a complete dislocation (luxation) or a posterior subluxation.
