QUESTION# 1
A 16-year-old presents to the emergency room with a possible head injury
from falling off his skateboard. The patient was wearing his helmet.
Examination reveals no outward head injury. What ICD-10-CM codes are
reported?
A. S09.90XA, V00.131A, Y93.51
B. V00.131A, Y93.51, S09.90XA
C. Correct: Z04.1, V00.131A, Y93.51
D. S09.90XA, Z04.1, V00.131A, Y93.51
Feedback: The patient had a possible head injury. ICD-10-CM coding
guideline, section IV.H indicates not to code diagnoses that indicate
uncertainty. The head injury code, S09.90XA, is not reported. ICD-10-CM
guideline, I.21.c.6, Observation Codes are reported when a person is being
observed for a suspected condition that is ruled out. In the ICD-10-CM
Alphabetic Index look for Observation/accident/transport referring you to
Z04.1. Verify code in the Tabular List. The observation codes are to be used
as a principal diagnosis only. ICD-10-CM guideline, I.C.20.a.6, An External
Cause code can never be a principal diagnosis. Look in the Alphabetical
Index to External Causes of Injures for
Accident/transport/pedestrian/conveyance/skateboard/fall. This index refers
you V00.131, which needs a 7th character A. Then look for
Activity/skateboarding. This refers you to Y93.51. Verify all codes in the
Tabular List.

Fracture, traumatic/wrist and you are referred to subcategory S62.10. Turn to
subcategory S62.10 in the Tabular List. Most fractures require 6th and 7th

the 6th character is for laterality; S62.102 specifies left wrist. For the 7th
character, reference the list under the category heading S62. The notes
under this heading indicate a fracture not indicated as open or closed is
coded as closed. Then it lists the appropriate 7th character: A is for initial
encounter for closed fracture. The correct code for this wrist fracture is
S62.102A.
