Unspecified injury of oth intrathoracic organs, init encntr

This code signifies an injury to an intrathoracic organ not specifically listed elsewhere, where the precise nature of the injury is unknown or not documented. It covers damage to organs within the chest cavity, excluding the heart and lungs, when the specific type of trauma (e.g., laceration, contusion) is not identified.

This code is appropriate when diagnostic imaging or surgical exploration reveals an injury to an intrathoracic organ such as the esophagus, trachea, or diaphragm, but the exact pathology of the injury remains undiagnosed. It is used for the initial treatment of such an injury, prior to definitive diagnosis or resolution.

• Only use this code when the specific intrathoracic organ is known, but the type of injury is not.
• Avoid this code if a more specific injury or organ code is available.
• Ensure the "A" seventh character is used only for the initial encounter for care.
