Injury to diaphragm, without mention of open wound into cavity

This code signifies a non-penetrating injury to the diaphragm, such as a rupture, tear, or contusion, resulting from blunt force trauma. It specifically excludes cases where there is an open wound extending into the thoracic or abdominal cavity. The injury compromises the integrity or function of the diaphragm without an external opening.

Use this code for diagnoses of diaphragmatic injury documented as blunt trauma, such as from motor vehicle accidents, falls, or direct blows to the torso, where no open wound is present. Documentation should clearly state the diaphragm as the injured structure and confirm the absence of an open wound communicating with the body cavities.

• Ensure documentation explicitly states "without open wound" or implies blunt trauma without penetration.
• Distinguish from penetrating diaphragmatic injuries, which would involve an open wound.
• Always sequence this code after the primary injury or external cause code, if applicable.
