Coracohumeral (ligament) sprain

This code represents a sprain or tear of the coracohumeral ligament, a key stabilizing structure of the shoulder joint. This injury typically results from trauma or overuse, leading to pain, swelling, and restricted range of motion in the shoulder. It specifically refers to damage to the ligament itself, not other surrounding soft tissues.

Use this code when documentation clearly indicates a sprain of the coracohumeral ligament, often diagnosed following a specific injury event such as a fall or sudden twisting motion of the arm. Supporting documentation should include a physician's diagnosis, physical examination findings consistent with a ligamentous injury, and potentially imaging results ruling out fractures or other significant shoulder pathology.

• Ensure the documentation explicitly states "coracohumeral ligament" to differentiate from other shoulder ligament sprains.
• Do not use this code for general shoulder pain or unspecified shoulder sprains; a more specific code would be required.
• Consider sequencing this code after any acute injury codes (e.g., fracture) if the sprain is a secondary diagnosis.
