Injury to unspecified blood vessel of thorax

This code signifies a traumatic injury to a blood vessel within the chest cavity when the specific vessel (e.g., aorta, subclavian artery, vena cava) is not identified in the medical record. It indicates damage such as a laceration, contusion, or rupture affecting a thoracic blood vessel due to external force or penetration.

Use this code when documentation clearly states a blood vessel injury in the thorax but lacks specificity regarding the exact vessel involved. This often occurs in initial emergency department assessments or when diagnostic imaging is inconclusive or pending. Supporting documentation would include physician notes describing a thoracic trauma with evidence of vascular compromise, such as hemothorax, without identifying the specific vessel.

• Avoid using this code if a more specific blood vessel injury (e.g., thoracic aorta, subclavian artery) is documented; always code to the highest level of specificity.
• Always sequence this code after the primary injury causing the trauma (e.g., fracture, open wound).
• Query the provider for more specific documentation if possible to identify the exact blood vessel involved, as this code represents an unspecified diagnosis.
