Coracoclavicular (ligament) sprain

This code signifies a sprain or tear of the coracoclavicular ligament, which connects the coracoid process of the scapula to the clavicle. This injury typically results from trauma to the shoulder, often involving a fall directly onto the shoulder or a direct blow. It is a key component of the acromioclavicular (AC) joint complex.

Use this code when documentation explicitly states a sprain or tear of the coracoclavicular ligament. This often occurs in conjunction with AC joint separations, particularly Rockwood Type III or higher. Supporting documentation includes physician notes detailing the mechanism of injury, physical examination findings (e.g., tenderness over the coracoclavicular ligaments, "step-off" deformity), and imaging reports (e.g., X-rays, MRI) confirming ligamentous injury.

• Differentiate from other shoulder sprains; ensure the documentation specifically mentions the coracoclavicular ligament.
• Frequently co-occurs with AC joint sprains (840.0, 840.6); sequence the more severe injury first if applicable.
• Avoid using for general shoulder pain or unspecified ligamentous injuries; precise anatomical documentation is crucial.
