Chapter 10 Review Exam Questions and
Answers
What part of the cardiovascular system is responsible for the one-way flow of blood through the
chambers of the heart? - correct answers:Heart valves
Rationale: Heart valves are made of flaps (cusps/leaflets) opening and closing like one way swinging
doors, preventing blood from flowing back.
How many layers of tissue does an artery have? - correct answers:Three
Rationale: An artery has three layers: an outer layer of tissue, a muscular middle and an inner layer of
epithelial cells.
The conduction system contains pacemaker cells, nodes, the ____ and the ____. - correct
answers:Purkinje fibers and bundle of His
Rationale: The conduction system contains pacemaker cells, nodes, the bundle of His and the Purkinje
fibers.
Repair of coronary vessel is called: - correct answers:Angioplasty
Rationale: Angio = vessel, plasty = repair
Which main coronary artery bifurcates into two smaller ones? - correct answers:Left
Rationale: The left main coronary artery branches into two slightly smaller arteries: the left anterior
descending coronary artery and the left circumflex coronary artery.
Intracoronary stents are placed percutaneously in the right coronary and left anterior descending
arteries for a patient with stenosis. Percutaneous transluminal balloon angioplasty is performed on the
left circumflex coronary artery. Choose the correct CPT® codes for this procedure. - correct
answers:92928-RC, 92928-LD, 92920-LC
Rationale: Only one base intervention is reported for each major coronary artery. The hierarchy from
highest to lowest is as follows: atherectomy, stent placement, followed by angioplasty. The base
intervention code 92928 is reported for the stent placement in the right coronary (92928-RC) and the left
anterior descending arteries (92928-LD). Each is reported with the corresponding coronary artery
modifiers. Look in the CPT® Index for Coronary Artery/Angioplasty/with Stent Placement and you are
, directed to 92928-92929. To locate the angioplasty code, look in the CPT® Index for Coronary
Artery/Angioplasty which directs you to 92920-92921. The base code 92920-LC is reported for the
angioplasty of the left circumflex.
In ICD-10-CM what is the default code for coronary artery atherosclerosis? - correct answers:I25.10
Atherosclerosis heart disease of native coronary artery without angina pectoris
Rationale: In the ICD-10-CM Alphabetic Index look for Atherosclerosis/coronary/artery which directs the
coder to I25.10. In addition, the coding for ICD-10-CM requires the documentation to state when there is
presence of angina pectoris. If angina pectoris is present, the coder also needs to confirm if the
documentation mentions a spasm.
What information is required to accurately code PVD with diabetes in ICD-10-CM? - correct
answers:Whether the patient has gangrene.
Rationale: PVD is the abbreviation for Peripheral Vascular Disease. ICD-10-CM indexes PVD with diabetes
with one code. For proper code selection the provider must document if the patient has gangrene or
not. Look in the ICD-10-CM Alphabetic Index for Diabetes, diabetic/with/peripheral angiopathy which
directs the coder to E11.51.
Aortography and bilateral extremity angiography were performed. The physician placed the catheter in
the aorta at the level of the renal arteries and injected contrast for the aortography and repositioned the
catheter just above the bifurcation for angiography of the lower extremities. Which CPT® codes are
reported? - correct answers:36200, 75625-26, 75716-26
Rationale: Because the catheter was repositioned, and separate studies were performed, both the
aortography and the extremity angiography are reported. Look in the CPT® Index for
Catheterization/Aorta which directs you to 36160-36200. In the CPT® Index see Aorta/Aortography and
you are referred to 75600-75630. To locate angiography of the lower extremities, look for
Angiography/Leg Artery referring you to 73706, 75635, 75710-75716. Modifier 26 reports the
professional service.
A physician states he performed a comprehensive EP study with induction of arrhythmia in the hospital.
The report shows bundle of His recording, pacing and recording of the right atrium, and induction of
arrhythmia by electrical pacing. What CPT® codeing is reported? - correct answers:93600-26, 93602-26,
93610-26, 93618-26
Rationale: Although the physician stated a comprehensive EP study was performed, the right ventricular
pacing and recording, and left atrial pacing and recording from the coronary sinus or left atrium were not
done. The components must be billed separately. Look in the CPT® Index for Electrophysiology Procedure
directing you to 93600-93660. The procedure was performed in the hospital; therefore, modifier 26 is
appended to all the codes to report the professional service.
