Subluxation of unsp acromioclavicular joint, init encntr

This code signifies a partial dislocation of the joint connecting the collarbone (clavicle) and the shoulder blade (scapula) at the acromion, where the specific side (left or right) is not documented. This injury typically results in pain, swelling, and limited shoulder movement.

Apply this code when documentation indicates an acromioclavicular joint subluxation without specifying laterality, and the patient is receiving initial active treatment for the injury. This is appropriate for new injuries or exacerbations of existing conditions that require new treatment.

• Only use this code when the medical record explicitly lacks documentation of laterality (left or right).
• Ensure the "A" seventh character is appropriate for the initial phase of care for this specific injury.
• If laterality is documented, select a more specific code (S43.111A or S43.112A).
