multiple-choice question is structurally optimized for student
review, featuring italicised answers and bold-italic explanations to
guarantee mastery of ICD-10-CM guidelines, query compliance,
and MS-DRG mechanics. It serves as the ultimate study guide
and high-yield testing resource for clinical documentation integrity
professionals and medical coders aiming to pass their certification
on the first attempt.
Section 1: Clinical Validation & Diagnoses
(Questions 1–15)
Q1. A patient is admitted with an acute
myocardial infarction. The chart shows a serum
sodium level of 122 mEq/L, and the physician
documents "hyponatremia" and orders
hypertonic saline. What is the most appropriate
action for the CDI specialist?
A) Do nothing, as hyponatremia is a common finding
in MI.
B) Query for clinical validation of the sodium level.
C) Query the physician to clarify if the hyponatremia
is acute or chronic.
,D) Code it as severe hyponatremia automatically.
Answer: C) Query the physician to clarify if the
hyponatremia is acute or chronic.
Rationale: Acute hyponatremia acts as a
Complication or Comorbidity (CC). Clarifying the
acuity captures the true severity of illness (SOI)
and risk of mortality (ROM).
Q2. A patient presents with a white blood cell
count of 19,000/mcL, respiratory rate of 24
breaths/min, and a confirmed source of
infection. The provider documents "SIRS due to
localized infection." What is the compliant next
step?
A) Code sepsis immediately because the patient
meets SIRS criteria.
B) Query for the clinical validation of sepsis.
C) Assign only the localized infection code.
D) Report the provider to the compliance officer.
Answer: B) Query for the clinical validation of sepsis.
Rationale: Meeting multiple SIRS criteria with an
active infection points toward sepsis, but a CDI
specialist cannot assume the diagnosis without
explicit provider documentation.
Q3. An elderly patient is admitted with severe
dementia and undergoes an altered mental
,status workup. The documentation shows a BMI
of 16.2, visible muscle wasting, and a note
stating "cachexia." No dietary interventions are
ordered. What should the CDI specialist do?
A) Clarify if the patient has severe protein-calorie
malnutrition.
B) Code cachexia as a Major CC (MCC).
C) Ignore the physical findings since no
supplements were ordered.
D) Document severe malnutrition in the progress
notes yourself.
Answer: A) Clarify if the patient has severe protein-
calorie malnutrition.
Rationale: A low BMI and muscle wasting
strongly support severe malnutrition (an MCC),
which carries far more weight than "cachexia"
alone.
Q4. A chart notes a serum creatinine rising from
a baseline of 0.8 mg/dL to 2.5 mg/dL within 24
hours. The provider documents "renal
insufficiency." What is the optimal query?
A) Leading query: "Please change renal insufficiency
to Acute Kidney Injury."
B) No query needed; the two conditions code to the
same default line.
, C) Query to clarify if the clinical presentation
represents Acute Kidney Injury (AKI).
D) Code AKI based on the KDIGO criteria directly.
Answer: C) Query to clarify if the clinical
presentation represents Acute Kidney Injury (AKI).
Rationale: "Renal insufficiency" does not
crosswalk to a CC, whereas Acute Kidney Injury
does. CDI specialists must request the precise
clinical term when indicators are present.
Q5. A patient with advanced COPD presents with
a pCO2 of 65 mmHg and a pH of 7.26. The
physician writes "COPD exacerbation with
respiratory distress." Which condition should be
queried?
A) Acute respiratory failure
B) Chronic respiratory failure
C) Acute bronchitis
D) Respiratory arrest
Answer: A) Acute respiratory failure
Rationale: Severe respiratory acidosis (pH < 7.35
and high pCO2) establishes the clinical picture
of acute respiratory failure, which functions as
an MCC.
Q6. The physician documents "pancytopenia" in
a patient undergoing active chemotherapy for
