Posterior dislocation of left sternoclavicular joint, init

This code signifies a backward displacement of the left sternoclavicular joint, which is the articulation between the sternum (breastbone) and the clavicle (collarbone). This type of dislocation is considered a serious injury due to its proximity to vital structures in the chest.

Use this code for the initial treatment of a patient presenting with a newly diagnosed posterior dislocation of the left sternoclavicular joint. This includes emergency department visits, initial consultations, and the first surgical repair or reduction of the dislocation.

• Always confirm the laterality (left) and the specific type of dislocation (posterior) from the physician's documentation.
• Ensure the encounter is indeed the "initial encounter" for this specific injury; subsequent care would use a different seventh character.
• Look for documentation of the mechanism of injury and any associated injuries, which may require additional codes.
