Sprain of left coracohumeral (ligament), initial encounter

This code signifies a sprain or tear of the coracohumeral ligament in the left shoulder. This ligament plays a crucial role in stabilizing the glenohumeral joint and can be injured through various mechanisms, often involving forceful external rotation or abduction of the arm.

Apply this code when a patient presents with a newly diagnosed sprain of the left coracohumeral ligament. This includes initial evaluations, diagnostic workups, and the beginning of treatment for the injury. It is appropriate for acute injuries where the patient is first seeking medical attention.

• Ensure documentation clearly specifies the left side and identifies the coracohumeral ligament as the injured structure.
• The "A" in the seventh character indicates an initial encounter for this specific injury, meaning the patient is receiving active treatment.
• Differentiate from other shoulder ligamentous injuries; this code is highly specific to the coracohumeral ligament.
