Injury to multiple and unspecified intrathoracic organs, without mention of open wound into cavity

This code signifies trauma affecting several internal organs within the chest cavity, or when the specific intrathoracic organs injured are not clearly documented. It specifically applies when there is no associated open wound penetrating the chest wall. This typically results from blunt force trauma.

Use this code for patients presenting with multiple internal chest injuries, such as a combination of lung contusion, cardiac contusion, and/or diaphragmatic injury, without a penetrating chest wound. Documentation should clearly indicate multiple intrathoracic organ involvement or an unspecified intrathoracic injury following blunt trauma.

• Ensure documentation specifies "without mention of open wound into cavity" to differentiate from penetrating injuries.
• Avoid using this code if specific intrathoracic organs are clearly identified and can be coded individually; this code is for multiple or unspecified injuries.
• Always sequence this code after the primary external cause of injury (E-code) if applicable.
