Inferior dislocation of unsp acromioclavicular joint, subs

This code signifies a downward displacement of the acromion from the clavicle at the acromioclavicular (AC) joint, where the specific side (left or right) of the body is not documented. This is a follow-up encounter for a previously diagnosed injury, indicating ongoing care, healing, or complications.

Apply this code for subsequent visits related to an inferior AC joint dislocation when the laterality is unspecified. This includes scenarios such as follow-up appointments for cast changes, physical therapy, monitoring healing progress, or addressing persistent symptoms after initial treatment.

• Ensure documentation clearly indicates an "inferior" dislocation and that the encounter is not the initial treatment.
• Only use this code when the medical record does not specify whether the dislocation is on the left or right side.
• Pair with external cause codes (V, W, X, Y) to describe the circumstances of the injury, if applicable and known.
