Dislocation of l acromioclav jt, > 200% displacmnt, init

This code signifies a severe separation of the left acromioclavicular (AC) joint, where the clavicle is displaced upward by more than twice its normal anatomical position relative to the acromion. This injury typically involves complete disruption of the AC ligaments and often the coracoclavicular ligaments, indicating a high-grade AC joint sprain or dislocation.

Apply this code for initial encounters with patients presenting with a left AC joint dislocation confirmed by imaging (e.g., X-ray, MRI) to have greater than 200% displacement. This typically corresponds to a Rockwood Type V or VI injury. Use this code when the patient is receiving active treatment for the injury.

• Ensure documentation clearly specifies "left" side and "greater than 200% displacement" for accurate code assignment.
• Verify this is the initial encounter for the specific injury; subsequent encounters will require a different seventh character.
• Distinguish from less severe AC joint separations (e.g., those with less displacement or subluxation) which are coded differently.
