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

This code describes a chronic or late effect of a severe dislocation of the left acromioclavicular (AC) joint, specifically one involving more than 200% displacement of the clavicle relative to the acromion. This indicates a persistent issue or complication arising from a past injury to the AC joint, rather than an acute event.

This code is appropriate for documenting long-term complications, residual pain, instability, or functional limitations stemming from a previously sustained, highly displaced left AC joint dislocation. It should be used when the patient is presenting for treatment of these ongoing sequelae, not for the initial injury.

• Always sequence this code after the primary diagnosis describing the specific sequela (e.g., chronic pain, instability).
• Ensure documentation clearly indicates the "sequela" nature of the encounter and the history of a severe left AC joint dislocation.
• Verify that the displacement percentage (greater than 200%) is explicitly stated or clearly implied in the patient's medical record.
