Posterior dislocation of unsp sternoclavicular joint, init

This code signifies a posterior displacement of the sternoclavicular joint, where the clavicle is dislocated backward relative to the sternum. This injury affects the joint connecting the collarbone to the breastbone, and the specific side (left or right) is not documented.

Apply this code for the initial treatment of a newly diagnosed posterior sternoclavicular joint dislocation when the laterality is not specified in the medical record. This typically occurs following trauma, such as a direct blow to the shoulder or a fall.

• Ensure the documentation clearly states "posterior dislocation" and that the encounter is for the initial treatment of the injury.
• If the laterality (left or right) is specified, a more specific code should be used.
• Do not use this code for anterior dislocations or for follow-up encounters.
