Subluxation of right acromioclavicular joint, init encntr

This code signifies a partial dislocation of the right acromioclavicular (AC) joint, where the clavicle (collarbone) and the acromion (part of the shoulder blade) have separated but are still in contact. This injury typically results in pain, swelling, and limited range of motion in the shoulder.

Apply this code for the initial treatment of a patient presenting with a right AC joint subluxation, such as after a fall directly onto the shoulder or a direct blow. It is appropriate for the first encounter for this specific injury, regardless of whether definitive treatment has begun.

• Ensure documentation clearly specifies "subluxation" versus a complete "dislocation" of the AC joint.
• Verify the laterality is explicitly stated as "right" in the medical record.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
