Disloc of unsp acromioclav jt, > 200% displacmnt, sequela

This code describes a chronic or late effect of a severe acromioclavicular (AC) joint dislocation where the clavicle is displaced significantly (over 200%) relative to the acromion. This indicates a persistent instability or deformity of the AC joint resulting from a past injury, rather than an acute event. The "unspecified" nature refers to the laterality (left or right) of the affected joint.

Use this code for documentation indicating a healed or chronic AC joint injury with persistent, severe displacement (greater than 200%) that is causing ongoing symptoms or requiring treatment. This applies when the initial injury occurred in the past and the patient is now presenting for management of the residual effects. This code is appropriate when the specific side of the body is not documented.

• Ensure documentation clearly states "greater than 200% displacement" and indicates a sequela or chronic condition.
• Do not use for acute dislocations; look for codes without the "S" seventh character.
• If laterality (left or right) is specified, choose a more specific code (S43.131S or S43.132S).
