Inferior dislocation of left acromioclavicular joint, init

This diagnosis code signifies a downward displacement of the left acromioclavicular (AC) joint, where the clavicle separates from the acromion. This injury typically involves significant ligamentous disruption, leading to instability and often a visible deformity.

Apply this code for a patient presenting with a newly diagnosed inferior dislocation of the left AC joint, such as following a fall directly onto the shoulder or a direct impact. This code is appropriate for the initial treatment phase, including evaluation, surgical repair, or initial non-operative management.

• Ensure documentation clearly specifies "inferior" dislocation and laterality (left).
• Confirm this is the patient's first encounter for this specific injury; subsequent encounters will require a different seventh character.
• Distinguish from superior or posterior dislocations, which have different codes.
