Final answer:
If a vessel injury occurs in combination with an associated organ and it is included in the organ injury AIS description, it should be coded as combined.
Step-by-step explanation:
If a vessel injury occurs in combination with an associated organ and it is included in the organ injury AIS (Abbreviated Injury Scale) description, it should be coded as combined. This means that both the vessel injury and the associated organ injury are considered as a single injury and are coded together as one. The AIS is a widely used injury severity scoring system that helps classify and prioritize injuries based on their severity.
For example, if a patient sustains a laceration to the liver along with injury to a hepatic vessel, both of these injuries would be classified and coded as a combined liver injury in the AIS descriptor.
