Unsp dislocation of unsp acromioclavicular joint, sequela

This code signifies a long-term complication or late effect stemming from a dislocation of the acromioclavicular (AC) joint, where the specific side (left or right) and the exact type of dislocation are not documented. Sequelae can include chronic pain, instability, limited range of motion, or degenerative changes that manifest after the initial injury has healed.

Apply this code when a patient presents with a current condition or symptom directly attributable to a past, unspecified AC joint dislocation, and the initial injury itself is no longer acute. This is appropriate for follow-up encounters addressing residual problems from the dislocation.

• This "S" code indicates a sequela, meaning the initial injury has resolved, and the current encounter addresses a residual condition.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic pain, osteoarthritis).
• Avoid using this code for acute or initial dislocations; those require codes from the initial encounter or subsequent encounter categories.
