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

This code signifies a severe dislocation of the acromioclavicular (AC) joint where the clavicle is displaced upward from the acromion by more than double its normal alignment. This indicates a complete disruption of all AC and coracoclavicular ligaments, often referred to as a Type V AC joint injury. It represents a significant traumatic injury to the shoulder girdle.

Apply this code for patients presenting with an acute, high-energy injury to the shoulder resulting in a grossly unstable AC joint with superior clavicular displacement exceeding 200%. This is typically diagnosed via X-ray or other imaging studies confirming the extent of the displacement. It is appropriate for the initial encounter for treatment of this specific injury.

• Ensure documentation clearly specifies "greater than 200% displacement" or "Type V" AC joint injury.
• Verify laterality if specified in the clinical notes; this code is for an unspecified side.
• Confirm this is the patient's initial encounter for this specific injury to use the "A" seventh character.
