Dislocation of l acromioclav jt, 100%-200% displacmnt, init

This code signifies a complete separation of the left acromioclavicular (AC) joint, where the clavicle is displaced upward by 100% to 200% relative to the acromion. This severe injury often involves significant ligamentous disruption and instability of the shoulder girdle.

This code is appropriate for the initial encounter of a patient presenting with a high-grade AC joint dislocation on the left side, typically resulting from a direct blow to the shoulder or a fall onto the outstretched arm. It is used when imaging confirms a complete superior displacement of the clavicle between 100% and 200%.

• Ensure documentation specifies "left" side and "100%-200% displacement" for accurate code assignment.
• Verify that this is the patient's initial encounter for this specific injury; subsequent care would use a different seventh character.
• Distinguish from less severe AC joint sprains or dislocations with less than 100% displacement.
