CPC CHAPTER 15 UPDATED ACTUAL EXAM QUESTIONS
AND CORRECT ANSWERS
Question 1.
What ICD-10-CM code is reported for suppurative otitis media in the right ear?
ANSWER
H66.41
Response Feedback:
Rationale: Look in the ICD-10-CM Alphabetic Index for Otitis/media/suppurative which directs
you to H66.4-. In the Tabular List a 5th character is required to identify the laterality.
Question 2.
A patient with mixed conductive and sensorineural hearing loss in the right ear has tried multiple
medical therapies without recovery of her hearing. Patient has consented to have an electromagnetic
bone conduction hearing device implanted in the temporal bone. What CPT® and ICD-10-CM codes
are reported?
ANSWER
69710-RT, H90.71
Response Feedback:
Rationale: In the CPT® Index look
for Hearing Aid/Implants/Bone Conduction/Implantation. You are referred to 69710. Review
the code to verify accuracy. In the ICD-10-CM Alphabetical Index look for Loss (of)/hearing
which states see also Deafness. Look for Deafness/mixed conductive and
sensorineural/unilateral. You are referred to H90.7-. Review the code in the Tabular List to
verify accuracy and 5th character 1 is for right ear.
, Question 3.
Mrs. Johns brought in her 9-month-old baby today, complaining that he has been fussy and
inconsolable. Indeed, James cried during the entire visit. Mrs. Johns believes her child has another case
of otitis media as this is the exact behavior exhibited last time. However, the exam reveals no infection,
no fever. Select the correct diagnosis code.
ANSWER
R68.12
Response Feedback:
RATIONALE: Look at the chief complaint—the reason for the visit—when considering the
primary diagnosis. In the ICD-10-CM Alphabetic Index look for Fussy baby directing you to code
R68.12. In this case, the mother thought her son had a recurring ear infection because of the
child's excessive crying. D is the correct answer because it is the chief complaint and no other
diagnosis was found. Codes Z00.129 and Z01.10 are inappropriate because these codes
describe routine exams in asymptomatic populations. Code H66.90 is incorrect, as no definitive
diagnosis is made.
Question 4.
A patient with a cyst like mass on his left external auditory canal was visualized under the microscope
and a microcup forceps was used to obtain a biopsy of tissue along the posterior superior canal wall.
What CPT® code is reported?
ANSWER
69105-LT
Response Feedback:
Rationale: In the CPT® Index look for Auditory Canal/External/Biopsy. Verify in the CPT®
numeric section. Code 69105 with modifier LT is correct since the biopsy was taken from the
left ear in the auditory canal.
Question 5.
Under general anesthesia, a provider excises one chalazion from each upper eyelid. What are the
procedure and diagnosis codes for the service?
ANSWER
67808-E1-E3, H00.11, H00.14
Response Feedback:
Rationale: In the CPT® Index look for Chalazion/Excision/Under Anesthesia directing you to
67808. Code 67808 describes the use of general anesthesia to excise single or multiple
chalazion(s). Modifiers E1 and E3 can be reported to indicate which eyelids were operated on.
In the ICD-10-CM Alphabetic Index look for Chalazion/right/upper H00.11 and
Chalazion/left/upper H00.14. Verify code selection in the Tabular List.
