Injury to diaphragm, with open wound into cavity

This code signifies a traumatic injury to the diaphragm that involves an open wound extending into either the thoracic or abdominal cavity. Such an injury typically results in a direct communication between the external environment and an internal body cavity, potentially leading to complications like pneumothorax, hemothorax, or organ herniation.

This code is appropriate for cases of penetrating trauma (e.g., stab wounds, gunshot wounds) where the diaphragm is lacerated and the wound tract communicates with the pleural or peritoneal space. Documentation should clearly state the diaphragm injury and explicitly mention the presence of an open wound extending into a body cavity.

• Differentiate from blunt diaphragmatic rupture, which does not involve an open wound into a cavity.
• Ensure documentation specifies the "open wound into cavity" aspect; simple diaphragmatic laceration without this detail may require a different code.
• Sequence this code as a primary diagnosis when it is the main reason for the encounter, followed by codes for associated injuries or complications.
