Unsp dislocation of left acromioclavicular joint, sequela

This code signifies a long-term or late effect resulting from a dislocation of the acromioclavicular joint in the left shoulder, where the specific type of dislocation was not documented at the time of the initial injury. It indicates that the patient is experiencing residual problems or complications directly attributable to this past injury.

This code is appropriate for encounters where a patient presents with chronic pain, instability, limited range of motion, or other persistent issues in the left shoulder that are documented as a direct consequence of a previously sustained, but unspecified, acromioclavicular joint dislocation. It should be used when the acute phase of the injury has passed and the patient is being treated for the lasting effects.

• Always assign a "sequela" code (7th character S) when the patient is being treated for a complication or residual effect of an old injury.
• Ensure documentation clearly links the current condition to the prior unspecified left acromioclavicular dislocation.
• Do not use this code for initial or subsequent encounters for the acute injury itself; those require different 7th characters.
