Free CCDS Practice Questions

Original questions with explanations

These original CCDS practice questions are educational examples designed to exercise reasoning. They are not recalled exam items and do not imply access to live or confidential test content.

Question 1

The progress notes contain conflicting descriptions of a condition affecting the admission. What is the best CDI response?

  • A. Choose whichever diagnosis gives the highest payment
  • B. Delete the conflicting note
  • C. Assign a diagnosis from a laboratory value alone
  • D. Review the full record and seek neutral clarification from the responsible provider when appropriate
Answer and explanation

D. Review the full record and seek neutral clarification from the responsible provider when appropriate Documentation integrity requires resolving meaningful ambiguity through a compliant process. Payment impact alone cannot determine the clinical conclusion.

Question 2

Which query wording is most problematic?

  • A. Please clarify the documented condition’s clinical specificity
  • B. Please document the higher-paying diagnosis so the case groups correctly
  • C. Please clarify the condition associated with these documented findings
  • D. The record contains conflicting descriptions; please clarify the diagnosis
Answer and explanation

B. Please document the higher-paying diagnosis so the case groups correctly The problematic wording directs the provider toward a financially preferred conclusion. A query should support accurate documentation rather than prescribe an answer for reimbursement.

Question 3

An elevated laboratory result is present without a provider diagnosis. What should a CDI specialist avoid?

  • A. Identifying an appropriate clarification opportunity
  • B. Consulting current coding and query guidance
  • C. Independently assigning a diagnosis solely from the abnormal result
  • D. Reviewing the clinical context
Answer and explanation

C. Independently assigning a diagnosis solely from the abnormal result Clinical indicators can support a clarification opportunity; they are not a license to substitute the reviewer’s diagnosis for the provider’s documentation.

Question 4

A CDI program’s case mix index rises sharply. What is the best interpretation?

  • A. Investigate case mix, documentation, coding, and service changes before drawing a conclusion
  • B. The rise proves every patient received better care
  • C. The rise proves fraud occurred
  • D. The rise has only one possible explanation
Answer and explanation

A. Investigate case mix, documentation, coding, and service changes before drawing a conclusion A summary metric may change for multiple reasons. Interpretation requires context, consistent definitions, and corroborating data.

Question 5

Which source should govern principal diagnosis sequencing for a practice scenario?

  • A. The diagnosis with the longest description
  • B. The applicable Official Guidelines for Coding and Reporting and relevant authoritative coding guidance
  • C. A reimbursement target
  • D. An informal shortcut from an old spreadsheet
Answer and explanation

B. The applicable Official Guidelines for Coding and Reporting and relevant authoritative coding guidance Sequencing follows applicable coding rules and documentation. Revenue targets and informal habits do not supersede official guidance.

Question 6

A CDI specialist and coder assigned different working and final DRGs. What is the most useful next step?

  • A. Assume the higher DRG is always correct
  • B. Accuse the other professional before reviewing the record
  • C. Change the diagnosis without provider clarification
  • D. Compare documentation and rule application collaboratively to identify and resolve the discrepancy
Answer and explanation

D. Compare documentation and rule application collaboratively to identify and resolve the discrepancy Reconciliation should examine the record and the governing rules. Collaboration helps distinguish missing documentation, sequencing differences, and legitimate final changes.

Question 7

Which dataset is safest for a public study discussion?

  • A. A screenshot with the name hidden but identifiable dates and details remaining
  • B. A coworker’s login session
  • C. A fictional case containing no identifiable patient information
  • D. A patient chart copied from the work system
Answer and explanation

C. A fictional case containing no identifiable patient information Fictional scenarios avoid disclosing protected information. Removing a name alone does not ensure the remaining details cannot identify a patient.

Question 8

A provider disagrees with a clarification request. Which response best supports professional communication?

  • A. Demand a particular diagnosis
  • B. Threaten a penalty for any disagreement
  • C. Silently alter the provider note
  • D. Explain the documentation ambiguity neutrally and follow the established escalation process if needed
Answer and explanation

D. Explain the documentation ambiguity neutrally and follow the established escalation process if needed CDI communication should identify the issue without coercing a clinical conclusion. An established process supports respectful resolution and record integrity.

Question 9

A dashboard reports 80 responses to 100 eligible queries. What is the response rate?

  • A. 20%
  • B. 100% because all queries were sent
  • C. 80%, provided numerator and denominator definitions are consistent
  • D. 125%
Answer and explanation

C. 80%, provided numerator and denominator definitions are consistent Response rate equals responses divided by eligible queries: 80/100. Comparisons also require consistent exclusions, periods, and definitions.

Question 10

Why should a CCDS candidate practice more than definition recall?

  • A. All questions require memorizing exact patient records
  • B. The exam has no clinical content
  • C. The exam includes application and analysis of documentation, coding, and professional scenarios
  • D. Definitions are never tested
Answer and explanation

C. The exam includes application and analysis of documentation, coding, and professional scenarios The linked ACDIS handbook describes recall, application, and analysis. Practice should include interpreting a scenario and explaining why other actions are inappropriate.

How to Review Your Results

For every missed item, name the tested concept, explain why the correct option is best, and identify the clue that rules out each distractor. Then review the corresponding official content domain.
