DOMAIN 1: FOUNDATIONAL KNOWLEDGE OF ANALYTICS IN
HEALTHCARE (14–16%)
Question 1. Which classification system is used in the United States to report
diagnoses for inpatient and outpatient encounters?
A. CPT
B. HCPCS Level II
C. ICD-10-CM
D. ICD-10-PCS
Rationale: ICD-10-CM (International Classification of Diseases, 10th Revision,
Clinical Modification) is the standard classification system for reporting diagnoses
in all U.S. healthcare settings, including inpatient and outpatient encounters. CPT
codes describe procedures and services, HCPCS Level II codes describe supplies
and equipment, and ICD-10-PCS codes describe inpatient procedures only.
Question 2. Which coding system is used to report inpatient hospital procedures
under ICD-10?
A. ICD-10-CM
B. CPT
C. ICD-10-PCS
D. HCPCS Level II
Rationale: ICD-10-PCS (Procedure Coding System) is used exclusively for
inpatient hospital procedure reporting in the United States. ICD-10-CM is for
diagnoses, CPT is for outpatient procedures and physician services, and HCPCS
Level II is for supplies, equipment, and drugs.
,Question 3. Medical severity diagnosis-related groups (MS-DRGs) represent a
prospective payment system implemented by CMS to reimburse hospitals a
predetermined amount for services provided to:
A. Outpatients
B. Inpatients
C. Emergency department patients
D. Long-term care residents
Rationale: MS-DRGs are part of the Medicare prospective payment system for
inpatient hospital services. They classify inpatient stays into groups based on
diagnosis, procedures, and complications, and hospitals receive a predetermined
payment per discharge. Outpatient services are reimbursed under the Outpatient
Prospective Payment System (OPPS), not MS-DRGs.
Question 4. A set of standards that provides universal names and codes for
laboratory and clinical results is:
A. LOINC
B. SNOMED CT
C. RxNorm
D. CPT
Rationale: LOINC (Logical Observation Identifiers Names and Codes) provides
universal identifiers for laboratory and clinical observations and results. SNOMED
CT is a comprehensive clinical terminology, RxNorm is for medications, and CPT
is for procedure coding.
Question 5. SNOMED CT is a _____-based terminology.
A. Code
B. Concept
C. Diagnosis
D. Procedure
Rationale: SNOMED CT (Systematized Nomenclature of Medicine — Clinical
Terms) is a concept-based terminology, meaning it organizes clinical terms around
,unique concepts rather than codes or specific classifications. This concept-based
structure enables semantic interoperability across different healthcare systems.
Question 6. Which of the following is NOT used to characterize procedures
performed on a patient?
A. ICD-10-PCS
B. CPT
C. ICD-10-CM
D. HCPCS Level II
Rationale: ICD-10-CM is used to code diagnoses, not procedures. ICD-10-PCS
codes inpatient procedures, CPT codes outpatient procedures and physician
services, and HCPCS Level II codes supplies, equipment, and drugs. ICD-10-CM
is the correct answer because it does not characterize procedures.
Question 7. The technology commonly utilized for automated claims processing
(sending bills directly to third-party payers) is:
A. Optical character recognition
B. Bar coding
C. Neural networks
D. Electronic data interchange
Rationale: Electronic data interchange (EDI) is the technology used for automated
claims processing, enabling the electronic exchange of healthcare transactions
(claims, remittances, eligibility inquiries) between providers and payers using
standardized formats such as X12 837 (claims) and X12 835 (remittance advice).
Question 8. Place of service codes are used on what type of billing form?
A. UB-04
B. CMS-1500
C. ADA Dental Claim Form
D. NCPDP Pharmacy Claim Form
, Rationale: Place of service codes (e.g., 11 for office, 21 for inpatient hospital, 23
for emergency department) are reported on the CMS-1500 claim form, which is
used for professional (physician) claims. The UB-04 is used for institutional claims
(hospital, skilled nursing facility).
Question 9. Which of the following best describes the four levels of healthcare
data analysis?
A. Descriptive, diagnostic, predictive, and prescriptive
B. Descriptive, inferential, predictive, and prescriptive
C. Descriptive, exploratory, predictive, and prescriptive
D. Descriptive, diagnostic, forecasting, and prescriptive
Rationale: The four generally accepted levels of healthcare data analysis are:
Descriptive (What happened?), Diagnostic (Why did it happen?), Predictive (What
will happen?), and Prescriptive (What should we do about it?). These levels
represent increasing analytical sophistication and value.
Question 10. Descriptive analytics answers which of the following questions?
A. What happened?
B. Why did it happen?
C. What will happen?
D. What should we do about it?
Rationale: Descriptive analytics summarizes historical data to answer "What
happened?" It provides reports, dashboards, and summary statistics that describe
past performance and current state. Diagnostic analytics answers "Why did it
happen?", predictive analytics answers "What will happen?", and prescriptive
analytics answers "What should we do about it?"
Question 11. Which of the following best describes the primary purpose of the
revenue cycle management process in healthcare?
A. To manage the financial aspects of patient care from preregistration
through final payment
B. To manage clinical documentation and coding
