CAISS AIS Coding Principles Practice Questions

Question 1

In AIS coding, what does the term 'NFS' (Not Further Specified) indicate when appended to a code?

Accepted Answer

The available information is insufficient to assign a more specific code

Answer

NFS indicates that the documentation lacks sufficient detail to assign a more precise AIS code, so the broadest applicable code is used.

Question 2

When coding bilateral injuries to paired organs (e.g., both kidneys), how should the coder proceed under AIS rules?

Accepted Answer

Code each injured organ separately using the same AIS code for each side

Answer

AIS requires separate coding for each side when paired organs are injured, even if the same code applies to both.

Question 3

Which AIS body region code (1–9) is assigned to injuries of the face?

Accepted Answer

2

Answer

AIS body region 2 covers the face, including facial bones, soft tissue, and sense organs of the face.

Question 4

A patient has a liver laceration described as 'minor.' What AIS severity score best corresponds to this injury?

Accepted Answer

2

Answer

A minor liver laceration typically maps to AIS severity 2 (moderate), as it involves parenchymal disruption without life threat.

Question 5

In the AIS coding structure, the third and fourth digits of the full seven-digit code specify which of the following?

Accepted Answer

Anatomic structure and specific nature of injury

Answer

The third and fourth digits identify the anatomic structure (e.g., liver, femur) within the body region.
