,Section A - Leadership AND Management
Q1.
A regional health information exchange (HIE) is implementing a new patient identification
strategy to ensure accurate record linkage across multiple sources. Which approach best
balances privacy, accuracy, and scalability, particularly for patients with incomplete
demographic data?
A. Use a single unique national patient B. Deploy a probabilistic matching algorithm
identifier assigned to every citizen at birth. that uses multiple demographic attributes
with weighted scores and thresholds.
C. Rely on exact deterministic matching D. Implement a biometric-based system that
using Social Security Number and date of captures fingerprints and retina scans at
birth. every point of care.
Correct: B - Deploy a probabilistic matching algorithm that uses multiple demographic
attributes with weighted scores and thresholds.
Rationale:Probabilistic matching handles missing or inaccurate data by using weighted
attributes, making it scalable and privacy-preserving. Deterministic methods fail with
incomplete data; national IDs raise privacy and political issues; biometrics are invasive and
not universally deployable.
Q2.
A hospital's coding team is reviewing a record for a patient who developed pneumonia
during a ventilator-associated event. The physician documented 'ventilator-associated
pneumonia' but did not specify the organism. According to current ICD-10-CM guidelines,
what is the correct coding approach?
A. Assign code J95.851 B. Query the physician for the specific
(Ventilator-associated pneumonia) as causative organism before assigning any
principal diagnosis. pneumonia code.
C. Assign a code for pneumonia due to D. Assign code J18.9 (Pneumonia,
unspecified organism, and sequence a unspecified organism) and do not code the
secondary code for the ventilator ventilator association because it is integral
association. to the pneumonia.
Correct: B - Query the physician for the specific causative organism before assigning any
pneumonia code.
Rationale:When documentation is unclear or incomplete, and specificity affects DRG
assignment and reimbursement, a query is required. Coding a nonspecific code without
querying when a more specific code is possible violates coding guidelines and may lead to
inaccurate data.

Q3.
A covered entity is planning to release a limited data set for research. Under HIPAA, which
of the following must be removed from the data set before disclosure?
A. Dates of admission and discharge B. Five-digit ZIP code
C. Medical record numbers D. Age in years
Correct: C - Medical record numbers
Rationale:A limited data set permits dates and geographic data (e.g., ZIP code) but requires
removal of all direct identifiers, including medical record numbers. Age is not a direct
identifier. Medical record numbers are direct identifiers and must be removed.
Q4.
A healthcare organization is implementing a data quality program. Which set of activities
best exemplifies the 'reliability' dimension of data quality?
A. Ensuring data are collected consistently B. Verifying that data values are within
across different systems and time periods. defined ranges and formats.
C. Confirming that data reflect the true D. Ensuring data are available when needed
clinical state of the patient. for decision-making.
Correct: A - Ensuring data are collected consistently across different systems and time
periods.
Rationale:Reliability refers to the consistency and stability of data over time and across
systems. Validity (B) checks format/range, accuracy (C) reflects truth, and timeliness (D)
relates to availability. Consistency is the hallmark of reliability.
Q5.
A health system is evaluating its revenue cycle performance. Which metric is most
directly impacted by the accuracy of clinical documentation improvement (CDI) efforts?
A. Days in accounts receivable (A/R) B. Case mix index (CMI)
C. Clean claim rate D. Patient satisfaction scores
Correct: B - Case mix index (CMI)
Rationale:CDI improves documentation specificity, which leads to more accurate and
higher-weighted DRG assignments, directly raising the case mix index. While clean claim rate
and A/R days can be affected, CMI is the most direct measure of documentation accuracy's
impact on reimbursement.
