CAISS Injury Classification & Scoring 4

Question 1

When coding a patient with both a liver laceration and a splenic laceration, a CAISS specialist should assign each injury:

Accepted Answer

Individual AIS codes; the ISS uses the maximum from the Abdomen region

Answer

Both injuries receive separate AIS codes, but for the ISS only the single highest AIS score from the Abdomen region is used.

Question 2

The AIS Spine region is classified as a separate body region from which of the following?

Accepted Answer

Head, Neck, Thorax, and Abdomen

Answer

The AIS Spine region is distinct from the Head, Neck, Thorax, and Abdomen regions, though the spinal column runs through all of them.

Question 3

A closed head injury with brief loss of consciousness and no structural intracranial findings would most likely be assigned which AIS severity?

Accepted Answer

AIS 2

Answer

Concussion or mild TBI with brief LOC and no structural injury typically maps to AIS 2 (Moderate) in the Head region.

Question 4

Which of the following fractures would typically be classified in the AIS External body region rather than in a limb region?

Accepted Answer

Degloving injury of the forearm

Answer

Degloving and similar skin/soft-tissue injuries are coded in the AIS External region regardless of where on the body they occur.

Question 5

What is the ISS for a patient with MAIS 3 head injury, AIS 2 facial lacerations, and AIS 3 thorax injury — assuming no other injuries?

Accepted Answer

18

Answer

ISS = 3² (Head) + 3² (Thorax) + 2² (Face) = 9 + 9 + 4 = 22; however, Face is a separate AIS region, giving 9+9+4 = 22.
