Q: How should you code asphyxia related to hanging? -
ANSWER-A: Asphyxia codes are located in the Other Trauma
section. Since we have no information as to neurological deficit,
the correct code to use is 020000.3. There are also codes in the
Head chapter for "hypoxic or ischemic brain damage secondary to
systemic hypoxemia, hypotension or shock" but these codes have
a severity code of 9.
Q: What is the correct code for a single tiny cerebral contusion? -
ANSWER-A: It is 140605.2 tiny: < 1 cm in diameter
Q: What is the correct code for a single small (1-4 cm) cerebral
contusion? - ANSWER-A: The correct code is 140606.3 which
identifies a single "small" contusion.
Q: What is a torn septum pellucida and which code would you use
if there was as associated IVH? - ANSWER-A: The septum
pellucida is the structure that separates the anterior horns of the
,2|Page
lateral ventricles, so when it is torn we would expect to see
intraventricular hemorrhage. The cerebral laceration should be
coded (140688.3) in addition to the IVH. Although the IVH is a
sequela of the tear, it is a codeable sequela
Q: Is a pterygoid fracture considered to be a skull base fracture? -
ANSWER-A: The pterygoid plates are a part of the sphenoid bone
and are therefore part of the skull base. The exception to this is if
they are included in a confirmed LeFort I fracture. In that case the
injury is coded to the face and the sphenoid (base fracture) and
the pterygoid is not coded additionally.
Q: What is Uncal herniation - ANSWER-A: Brain stem
compression; includes transtentorial (uncal)
Q: What constitutes a subacute SDH? - ANSWER-A: Subacute
subdural hematomas are defined arbitrarily as those that present
between 4 and 21 days after injury.

Q: What constitutes a chronic SDH? - ANSWER-A: Chronic
subdural hematomas are arbitrarily defined as those hematomas
presenting 21 days or more after injury.
Q: When and how do I code LOC? - ANSWER-A: You may use
codes 161002.2 through 161006.3 when the MD confirms
"positive LOC". This does not have to be witnessed by the MD. If
they believe there was LOC and document it, we may code it. We
do not need to have the word "concussion" in the chart in order to
code LOC. If the EMS agency notes LOC, the physician must
corroborate this finding in the medical record for you to code it in
AIS.
Q: If there is a cerebral hemorrhage NFS and LOC of some
duration, how should this be coded? May we use concussive
injury codes in addition to the hemorrhage code? - ANSWER-A:
Do not code coma in addition to the hemorrhage. When there is
an anatomic brain injury the concussive codes are not used
additionally. If the only injury is a skull fracture (no damage to the
brain substance) and there is documented LOC you may use the
concussive injury codes additionally.

Q: A patient is admitted after an assault with a baseball bat to the
head; among his injuries, a tympanic membrane rupture; How do
you code this injury? - ANSWER-A: a tympanic membrane rupture
is coded as 240216.1; note that frequently this injury is also
associated with a basilar skull fracture so look for that on the CT
scan or a clinical diagnosis of such.
Q: A woman is in MVC with facial trauma multiple fractures of R
orbit complains of loss of visual acuity in R eye. Her globe is intact
but a hole in her R macula is discovered. Please code this injury
to the eye. - ANSWER-A: Code 240904.2; Macula: hole
Q: How would you code this finding? Acute left parasymphyseal
fracture of the left hemi mandible. Fracture of the angle of the
right hemi mandible. When reviewing the physician notes they
state, "right angle and left parasymphyseal displaced mandible
fractures." - ANSWER-A: The mandible is one of the ring-like
bony structures that only receives 1 code. You should code it to
the largest mass area. As you go down the codes under
mandible, they increase in body mass, so you would use the code
for symphysis/parasymphysis 250614.2
