Posterior dislocation of right acromioclavicular joint, subs

This code signifies a posterior displacement of the acromioclavicular (AC) joint in the right shoulder, occurring during the healing or recovery phase of the injury. This type of dislocation involves the clavicle shifting backward relative to the acromion.

Utilize this code for follow-up visits where a patient is receiving ongoing care for a previously diagnosed posterior dislocation of the right AC joint. This includes encounters for cast changes, physical therapy, medication management, or wound care related to the initial injury. It is appropriate when the patient is no longer in the initial active treatment phase but still under care for the sequelae of the dislocation.

• Ensure documentation clearly specifies "posterior" dislocation and "right" side.
• Confirm the encounter is for follow-up care, not the initial treatment of the injury.
• Pair with external cause codes (V, W, X, Y) if the cause of the original injury is known and relevant to the current encounter.
