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

This code signifies a complete or near-complete separation of the right acromioclavicular (AC) joint, where the clavicle is displaced upward relative to the acromion by 100% to 200% of its normal anatomical position. This represents a severe injury, often involving rupture of both the acromioclavicular and coracoclavicular ligaments.

This code is appropriate for initial encounters with patients presenting with a high-grade right AC joint dislocation, typically a Type III or IV injury according to Rockwood classification, confirmed by imaging. It should be used when the displacement is clearly documented as 100% to 200%.

• Ensure documentation specifies "right" side and the "initial encounter" for treatment of this injury.
• Verify the percentage of displacement is explicitly stated or clearly inferable from imaging reports to be within the 100%-200% range.
• Distinguish from lesser degrees of AC joint separation or dislocations of other shoulder joints.
