CAISS Trauma Documentation 2 — Questions and Answers
Question 1: In AIS documentation, which term describes injuries that are not life-threatening but contribute to overall injury severity?
- Minor injuries
- Modifying factors (Correct answer)
- Non-critical injuries
- Supplemental injuries
Correct answer: Modifying factors
Modifying factors in AIS documentation account for injuries that influence overall severity without being individually life-threatening.
Question 2: When documenting a fractured femur in the AIS, which body region is it coded under?
- Spine
- Extremities (Correct answer)
- Pelvis
- Abdomen
Correct answer: Extremities
The femur is part of the lower extremity, so femur fractures are coded under the Extremities body region in the AIS.
Question 3: Which AIS severity level is assigned to injuries described as 'severe, not life-threatening'?
- AIS 2
- AIS 3 (Correct answer)
- AIS 4
- AIS 5
Correct answer: AIS 3
AIS 3 corresponds to injuries classified as severe but not life-threatening in the AIS severity scale.
Question 4: What does the term 'polytrauma' refer to in trauma documentation?
- A single catastrophic injury
- Multiple injuries to one body region
- Simultaneous injuries to two or more body regions (Correct answer)
- Injuries requiring multiple surgeries
Correct answer: Simultaneous injuries to two or more body regions
Polytrauma refers to simultaneous injuries affecting two or more body regions, each with an AIS score of 3 or greater.
Question 5: In the AIS, how is a ruptured spleen WITHOUT major vascular involvement typically classified?
- AIS 1
- AIS 2
- AIS 3 (Correct answer)
- AIS 4
Correct answer: AIS 3
A ruptured spleen without major vascular involvement is typically coded as AIS 3 (severe, not life-threatening) in the Abdomen region.
Question 6: Which document is the primary reference used by CAISS specialists to assign accurate AIS codes?
- ICD-10 Manual
- AIS Dictionary/Coding Manual (Correct answer)
- DSM-5
- ATLS Guidelines
Correct answer: AIS Dictionary/Coding Manual
The AIS Dictionary (Coding Manual) published by AAAM is the primary reference for assigning accurate AIS injury codes.
Question 7: What is the correct approach when a trauma record describes an injury that does not exactly match an AIS descriptor?
- Skip the injury and leave it uncoded
- Code the closest matching descriptor using clinical judgment (Correct answer)
- Always assign AIS 1 for unclear injuries
- Contact the treating physician before coding
Correct answer: Code the closest matching descriptor using clinical judgment
When an exact match is unavailable, coders use clinical judgment to select the closest matching AIS descriptor based on injury characteristics.
