1. How should a gunshot wound (GSW) be coded when the missile is lodged in
the bone?
A. Closed fracture
B. Soft-tissue penetrating injury
C. Open fracture (per clarification document)
D. Bone contusion
2. How are bony fractures resulting from a GSW coded?
A. Closed fracture
B. Penetrating injury
C. Soft-tissue injury
D. Open fracture
3. How are bone contusions coded in AIS?
A. Minor fracture
B. Contusion code
C. They are not codeable
D. Soft-tissue injury
4. When can compartment syndrome of the upper extremity be coded?
A. Only when associated with a major fracture
B. Only following vascular injury
C. Only when caused by soft-tissue trauma without fracture or structural
,destruction
D. Only when due to burns
5. What does a crush injury involve?
A. Mild soft-tissue bruising
B. Bone damage only
C. Vascular damage only
D. Massive destruction of skeletal, vascular, nervous, and tissue systems
6. Degloving injuries to the upper extremity are assigned to which category?
A. Skeletal
B. Vascular
C. External injury category
D. Joint injuries
7. What should be considered when assigning penetrating injury codes to the
upper extremity?
A. Use only when bone is fractured
B. Use only for injuries above the elbow
C. Use when penetration does NOT involve bone or internal structures; specific
codes exist for tissue loss >25 cm² or blood loss >20% depending on level of injury
D. Use only for foreign body removal
8. How is a major laceration of the upper extremity defined?
A. >5 cm anywhere
B. >10 cm anywhere
C. >10 cm on the hand OR >20 cm on the extremity extending into subcutaneous
tissue
D. Only if muscle is exposed
9. What distinguishes a minor from a major avulsion of the upper extremity?
A. Minor involves muscle; major involves bone
B. Minor <100 cm² anywhere; major >100 cm² anywhere
C. Minor ≤25 cm² on hand or ≤100 cm² entire extremity; major >25 cm² on hand
, or >100 cm² entire extremity
D. Minor is superficial; major requires surgery
10. What is a key consideration when coding vessel injuries in the upper
extremity?
A. Always code separately regardless of other injuries
B. Do not code separately if part of crush/amputation unless vascular injury is
more severe; branches coded only if named or specifically listed
C. Always code branch vessels
D. Only code major arteries
11. A vascular injury in the upper extremity that is not further specified receives
what severity?
A. AIS 3
B. AIS 6
C. AIS 9 (unspecified)
D. AIS 0
12. True or False: Laceration, perforation, and puncture are coded the same in
the vessel section.
A. False
B. True
13. How is a minor vessel laceration described?
A. Circumferential with >20% blood loss
B. Superficial; incomplete circumferential involvement; ≤20% blood loss by volume
C. Segmental loss of vessel
D. Full transection
14. True or False: In the vessel section, major injuries include rupture,
transection, and segmental loss.
