Question 1
A newly hired medical coder is asked to explain the primary purpose of coding to a
patient accounts representative. Which response is most accurate?
A. Coding converts insurance payments into written clinical documentation.
B. Coding translates documented diagnoses, services, procedures, and supplies into
standardized alphanumeric or numeric codes.
C. Coding determines which treatment a physician should provide.
D. Coding replaces the need for a complete medical record.
Correct Answer: B. Coding translates documented diagnoses, services,
procedures, and supplies into standardized alphanumeric or numeric codes.
Rationale: Medical coding converts information documented in the health record into
standardized codes used for reimbursement, reporting, research, and data analysis.
Coders do not determine treatment or replace documentation. Insurance payments
may be influenced by assigned codes, but coding does not convert payments into
clinical information. Accurate coding must always begin with the provider’s
documentation.
Question 2
A coder notices that a patient’s diagnosis appears clinically likely but is not
documented by the treating provider. What is the most appropriate action?
A. Assign the diagnosis because the clinical findings support it.
B. Select the diagnosis that produces the highest reimbursement.
C. Code only the documented information and query the provider when clarification
is necessary.
D. Ask the patient to confirm the diagnosis.
Correct Answer: C. Code only the documented information and query the
provider when clarification is necessary.
Rationale: Code assignment is based on provider documentation and the official rules
governing the applicable code set. A coder may recognize clinical indicators but
cannot independently diagnose the patient. When documentation is incomplete,
conflicting, or unclear, a compliant provider query may be submitted. Reimbursement
considerations must never determine which diagnosis is reported.

Question 3
Which combination of competencies is most essential for a medical coder responsible
for reviewing complex operative reports?
A. Anatomy, medical terminology, and attention to detail
B. Marketing, public relations, and financial investing
C. Pharmacology, nursing licensure, and hospital administration
D. Computer programming, statistics, and laboratory testing
Correct Answer: A. Anatomy, medical terminology, and attention to detail
Rationale: Coders must understand anatomy to identify body sites, medical
terminology to interpret diagnoses and procedures, and detailed documentation to
apply coding rules correctly. Although knowledge of pharmacology, technology, and
finance may occasionally be helpful, these areas do not replace the foundational
competencies required to analyze clinical records and select accurate codes.
Question 4
During claim preparation, which items would generally require coding when
supported by the medical record?
A. Only the patient’s primary diagnosis
B. Diagnoses, reportable services or procedures, and applicable supplies
C. Only services personally performed by a physician
D. Every statement made by the patient during the encounter
Correct Answer: B. Diagnoses, reportable services or procedures, and applicable
supplies
Rationale: Coders assign codes to reportable diagnoses, procedures, services, and
supplies according to the relevant classification or coding system. Not every statement
in the record is coded, and coding is not limited to physician services. Each reported
item must be supported by documentation and meet applicable coding, coverage, and
billing requirements.
Question 5
Why can inaccurate code assignment have a significant financial effect on a
healthcare organization?
A. Codes determine the patient’s clinical prognosis.
B. Codes may influence reimbursement under payment systems used by insurers.
,2026/2027
C. Codes automatically establish medical necessity.
D. Codes allow providers to charge any amount they choose.
Correct Answer: B. Codes may influence reimbursement under payment systems
used by insurers.
Rationale: Many payment methodologies use diagnosis and procedure codes to
calculate or classify reimbursement. Inaccurate coding may result in underpayment,
overpayment, denials, or compliance exposure. Codes do not establish prognosis,
guarantee medical necessity, or permit unrestricted charges. Documentation, payer
policies, contracts, and payment rules all affect the final reimbursement determination.
Question 6
While reviewing a hospital record, a coder finds that the operative report lacks a clear
description of the procedure performed. What should the coder do first?
A. Assign the procedure listed on the scheduling form.
B. Code the most common procedure performed for the diagnosis.
C. Seek clarification through the organization’s compliant query process.
D. Omit the entire claim without notifying anyone.
Correct Answer: C. Seek clarification through the organization’s compliant
query process.
Rationale: Coders evaluate records for completeness and accuracy and communicate
with providers when clinically significant information is unclear. A scheduling form
or probable procedure cannot substitute for authenticated documentation of what was
performed. Omitting the claim without attempting clarification may unnecessarily
delay reimbursement and leave the record incomplete.
Question 7
A technician specializes in assigning diagnoses and procedures for inpatient hospital
stays. Which title most appropriately describes this role?
A. Medical coding specialist
B. Pharmacy benefits manager
C. Insurance underwriter
D. Utilization review nurse
Correct Answer: A. Medical coding specialist
Rationale: Professionals who code inpatient hospital services may be called health
information coders, medical record coders, coding specialists, or coders/abstractors.
Insurance underwriters evaluate insurance risk, pharmacy benefits managers
administer drug benefits, and utilization review nurses assess the appropriateness or
efficiency of care rather than primarily assigning codes.

Question 8
A Medicare inpatient claim is assigned to a group based on the patient’s diagnoses,
procedures, severity, and other qualifying factors. Which payment classification is
being applied?
A. Ambulatory Payment Classification
B. Medicare Severity–Diagnosis Related Group
C. Resource-Based Relative Value Scale
D. National Drug Code classification
Correct Answer: B. Medicare Severity–Diagnosis Related Group
Rationale: Medicare Severity–Diagnosis Related Groups, or MS-DRGs, classify
inpatient hospital stays for prospective payment. The assigned group reflects factors
such as the principal diagnosis, procedures, complications, comorbidities, discharge
status, age, and sex. APCs apply primarily to hospital outpatient services, while the
RBRVS is associated with physician payment.
Question 9
Which statement best describes an electronic health record?
A. A database used only to store insurance payments
B. A digital version of health information that may support documentation, care,
coding, and information exchange
C. A coding manual that replaces ICD-10-CM and CPT
D. A record maintained exclusively by patients
Correct Answer: B. A digital version of health information that may support
documentation, care, coding, and information exchange
Rationale: An electronic health record contains digital clinical and administrative
information used by authorized healthcare professionals. It can support documentation,
communication, care coordination, coding, and billing. It does not replace official
coding systems and is not limited to insurance information or records maintained
solely by the patient.
Question 10
An experienced coder wants to advance beyond routine code assignment. Which
career path is most consistent with the coder’s existing expertise?
A. Coding auditor or educator
B. Radiologic technologist without further training
