Carcinoma of multiple overlapping sites of the bladder. Diagnostic cystoscopy and
transurethral fulguration of bladder lesions over the dome and posterior wall (1.9
cm.) was completed. A biopsy was taken of a lesion in the lateral wall. What
modifier should be added to the biopsy procedure code?
a. -50, Bilateral procedure
b. -51, Multiple procedures
c. -59, Distinct procedural service
d. -99, Multiple modifiers
Correct Answer: C
The surgery is done on two distinct areas within the bladder with two distinct
approaches. The biopsy is not of the area that was resected and warrants the use
of -59 (CPT Assistant Sept. 2001; CPT Professional Edition 2020, Appendix A).
A bronchoscopy with multiple biopsies of the left bronchus was completed and
revealed adenocarcinoma. What, if any, modifier should be added to the
procedure code billed by the facility?
a. -59, Distinct procedural service
b. -51, Multiple procedures
c. -76, Repeat procedure or service by same physician
d. No modifiers should be reported

Correct Answer: D
The procedure is reported with code 31625, the description of which indicates
biopsy of single or multiple sites. When reporting this code, it is not necessary to
indicate multiple procedures as the code itself does that (AMA CPT Professional
Edition 2020, Appendix A).
A patient is admitted with fever and urinary burning. Urosepsis is suspected. The
discharge diagnosis is Escherichia coli, urinary tract infection; sepsis ruled out.
Which of the following represents the diagnoses to report for this encounter and
the appropriate sequencing of the codes for those conditions?
a. Fever, urinary burning, urosepsis
b. Fever, urinary burning, sepsis
c. Escherichia coli sepsis
d. Urinary tract infection, Escherichia coli
Correct Answer: D
Symptoms are not coded when a related definitive diagnosis is present on
discharge. The patient has a discharge diagnosis of urinary tract infection,
secondary to E. coli. A secondary code of B96.20 is assigned to identify E. coli as
the cause of the infection (CMS 2020a, Section II.A., 108).
A patient was admitted to the emergency department for abdominal pain with
diarrhea and was diagnosed with infectious gastroenteritis. In addition to
gastroenteritis, the final diagnostic statement included angina and chronic
obstructive pulmonary disease. List the diagnoses that would be coded and their
correct sequence.
a. Abdominal pain, infectious gastroenteritis, chronic obstructive pulmonary
disease, angina
b. Infectious gastroenteritis, chronic obstructive pulmonary disease, angina

, CCS Practice Exam PREP
c. Gastroenteritis, abdominal pain, angina
d. Diarrhea, chronic obstructive pulmonary disease, angina
Correct Answer: B
The abdominal pain and diarrhea are not coded as they are symptoms integral to
the diagnosis of infectious gastroenteritis. Review Coding Guideline IV.D for
additional information on coding of symptoms, signs, and ill-defined conditions
(CMS 2020a, Section IV.D., 113).
A patient was admitted to the endoscopy unit for a screening colonoscopy. During
the colonoscopy, polyps of the colon were found and a polypectomy was
performed. What diagnostic codes should be used and how should they be
sequenced?
Z12.11Encounter for screening for malignant neoplasm of colon
D12.6Benign neoplasm of colon, unspecified
Z86.010Personal history of colonic polyps
a. Z12.11, Z86.010
b. D12.6, Z12.11, Z86.010
c. Z12.11, D12.6
d. D12.6, Z12.11
Correct Answer: C
The circumstances of the encounter are for a screening colonoscopy. Because of
this screening, colonoscopy is listed first, followed by a code for the polyps (CMS
2020a, Section I.C.21.c.5, 97-98).
The patient is admitted for chest pain and is found to have an acute inferior
myocardial infarction with coronary artery disease and atrial fibrillation. After the
atrial fibrillation was controlled and the patient was stabilized, the patient
underwent a CABG ×2 from aorta to the right anterior descending and right
obtuse, using the left greater saphenous vein which was harvested via an open

approach. Cardiopulmonary bypass was utilized. The appropriate sequencing and
ICD codes for the hospitalization would be:
I25.10Atherosclerotic heart disease of native coronary artery without angina
pectorisI21.19ST elevation (STEMI) myocardial infarction involving other coronary
artery of inferior wallI22.1Subsequent ST elevation (STEMI) myocardial infarction

d. I22.1, I48.91, I21.19, 021109W
Correct Answer: C
The patient's hospitalization includes a definitive diagnosis of myocardial
infarction of the inferior wall as well as the other diagnoses of coronary artery
disease and atrial fibrillation. The chest pain is not coded as it is a symptom of the
MI. The patient underwent CABG ×2 with cardiopulmonary bypass and harvesting
of the left saphenous vein to be used as graft material. All three procedures are
reportable and should be coded (Leon-Chisen 2020, 393-396, 430- 434).
A patient is admitted with hemoptysis. A bronchoscopy with transbronchial biopsy
of the lower lobe was undertaken that revealed squamous cell carcinoma of the
right lung. Which conditions should be identified as present on admission?
C34.30Malignant neoplasm of lower lobe, unspecified bronchus or lung
C34.31Malignant neoplasm of lower lobe, right bronchus or lung
