Posterior dislocation of right acromioclavicular joint, init

This code signifies a posterior displacement of the acromial end of the clavicle from its articulation with the acromion of the scapula, specifically affecting the right shoulder. This injury involves the disruption of the ligaments supporting the acromioclavicular joint, with the clavicle positioned behind the acromion.

Apply this code for a patient presenting with a newly diagnosed posterior dislocation of the right acromioclavicular joint. This includes initial evaluations, emergency department visits, or the first encounter for treatment of this specific injury. It is appropriate when the patient has not received definitive treatment for this dislocation previously.

• Ensure documentation specifies "posterior" dislocation and "right" side.
• Confirm this is the initial encounter for this specific injury, not a subsequent visit or sequela.
• Distinguish from anterior or superior dislocations, as those have different codes.
