✔✔(T/F) Clinical diagnosis alone are not codable for certain injuries. - ✔✔T
✔✔(T/F) In order to code clinical diagnosis, there must be back-up with a CT, MRI or
autopsy documentation. - ✔✔T
✔✔(T/F) Cranial Nerve Injuries or Basilar Skull Fractures are an exception to coding
clinical diagnosis. - ✔✔T
✔✔Basilar Skull Fracture - ✔✔Physical signs of raccoon eyes, Battle signs, CSF
rhinorrhea, CSF otorrhea and Hemotympanum are indications of what?
✔✔(T/F) AIS allows coding of cranial nerve "contusion" if there is documented cranial
nerve weakness/paresis or subtotal loss of function? - ✔✔T
✔✔(T/F) AIS allows coding of cranial nerve "laceration" if there is documented cranial
nerve paralysis, or total loss of function? - ✔✔T
✔✔(T/F) Coding a basilar skull fracture based on physical signs or manifestations is
only permitted if there is evidence of traumatic head injury or the physical
manifestations cannot be related to a peripheral or facial injury (e.g., facial fractures)? -
✔✔T
✔✔(T/F) Complications are coded as injuries? - ✔✔F
,✔✔(T/F) Do not assume that a specific injury has occurred simply because a particular
outcome occurred. - ✔✔T
✔✔(T/F) Death is an automatic AIS .6. - ✔✔F
✔✔(T/F) An AIS of .1 can result in death. - ✔✔T
✔✔(T/F) Vertebral fractures and contusions are coded separately. - ✔✔F
✔✔(T/F) Penetrating injuries that do not injure underlying structures should be coded in
the Whole Area section of the dictionary chapter and assigned to the External ISS body
region. - ✔✔T
✔✔(T/F) In penetrating injuries, you should code the overlying skin injury, not just the
organ injury. - ✔✔F
✔✔(T/F) Bullet wounds associated with fractured bones should be coded as open
fractures. - ✔✔T
✔✔(T/F) A bullet can pass through soft tissue/skin only, completely missing other
organs and systems, and cause only an AIS .1 injury. - ✔✔T
✔✔(T/F) The not further specified (NSF) category allows for coding injuries when
detailed information is lacking. - ✔✔T
✔✔Open Fracture - ✔✔Skin overlying the fracture is lacerated.
✔✔Closed Fracture - ✔✔Skin overlying the fracture is not lacerated.
✔✔Articular Fracture - ✔✔Fracture involving the joint.
✔✔Comminuted Fracture - ✔✔Multiple bone fragment fracture
✔✔Displaced Fractrue - ✔✔Fracture in which two ends of the bone are not aligned
✔✔Complex Fracture - ✔✔Fracture with three or more fragments with the proximal and
distal fragments not touching
✔✔Sprain - ✔✔Injury to joints
✔✔Strain - ✔✔Injury to muscles, tendons
, ✔✔Crush - ✔✔Massive destruction of body part with damage to underlying body
systems (e.g., skeletal, organ and vascular)
✔✔Amputation - ✔✔Total loss of body part from trauma or burn
✔✔Vessel Laceration - ✔✔Same as puncture or perforation
✔✔Minor vessel laceration - ✔✔Superficial, incomplete circumferential involvement,
blood loss less than or equal to 20% by volume
✔✔Major vessel laceration - ✔✔Rupture, transection, segmental loss, complete
circumferential involvement, blood loss > 20% by volume
✔✔Thrombosis - ✔✔Includes any injury to the vessel resulting in its occlusion
✔✔Muscle laceration - ✔✔same as rupture, tear or avulsion
✔✔> 20% blood loss in adults - ✔✔> 1000 cc
✔✔Nerve paresis (palsy) - ✔✔Subtotal loss of function
✔✔Nerve paralysis - ✔✔Total loss of function
✔✔Transection, Laceration, Contusion & Segmental Spasm,
Aneurysm/Pseudoaneurysm, A-V Fistula, Intimal Flap - ✔✔Types of Arterial Injuries
✔✔(T/F) You should code conservatively. - ✔✔T
✔✔(T/F) Foreign bodies are not injuries and therefore not coded. - ✔✔T
✔✔(T/F) You should base the injure severity based on procedure or treatment
interventions. - ✔✔F
✔✔(T/F) Multiple fractures to the same bone but in different regions of the bone are
coded separately. - ✔✔T
✔✔(T/F) "Crush" should only be used when vascular, skeletal and soft tissue injury
occur with an injury. - ✔✔T
✔✔(T/F) If "crush" code is used, you should also code the injuries separately. - ✔✔F
✔✔(T/F) Transection should be coded as a complete transection. - ✔✔T
