Dislocation of r acromioclav jt, > 200% displacmnt, subs

This code signifies a severe, previously diagnosed dislocation of the right acromioclavicular (AC) joint where the clavicle is displaced upward by more than twice its normal width relative to the acromion. This indicates a highly unstable injury, often involving complete rupture of both the acromioclavicular and coracoclavicular ligaments.

This code is appropriate for follow-up encounters, such as post-operative visits, physical therapy sessions, or subsequent clinic evaluations, for a patient who has already received initial treatment for this specific type of severe right AC joint dislocation. It should be used when monitoring healing, assessing complications, or managing ongoing care after the initial injury.

• Ensure the documentation clearly specifies "greater than 200% displacement" for the right AC joint.
• Verify that this is a subsequent encounter, not the initial treatment for the injury.
• Pair with external cause codes (e.g., W00-Y38) if the cause of the initial injury is relevant and documented.
