Worked examples: how to reason through CCDS questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: A patient receives IV contrast for CT imaging and develops a creatinine rise of 0.5 mg/dL (from 1.0 to 1.5 mg/dL) 48 hours later. The radiologist notes 'contrast nephropathy.' How should this be coded?

1. N17.9 with an adverse effect code for contrast media
2. T45.8X5A as the principal diagnosis
3. N14.11 as nephropathy induced by contrast media
4. Only code the underlying condition requiring the CT scan

Answer: C. N14.11 as nephropathy induced by contrast media

Explanation:

The correct answer is N14.11. The radiologist documented contrast nephropathy, and ICD-10-CM has a specific code for nephropathy induced by contrast media, so that diagnosis is coded as stated. The adverse effect code for the contrast agent is added to show the cause.

N17.9 is wrong because it is unspecified acute kidney failure, and nothing in the documentation calls this acute kidney injury; a creatinine rise from 1.0 to 1.5 mg/dL is a lab value, not a diagnosis. T45.8X5A is wrong because adverse effect codes describe the cause and are never the principal diagnosis. Coding only the underlying condition behind the CT leaves out a documented complication.

Rule to remember: code the diagnosis the provider documents, use the most specific code available, and pair a drug or agent reaction with its adverse effect code as a secondary code. Do not turn lab changes into diagnoses without a query.

Example 2

Question: A patient develops a catheter-associated urinary tract infection (CAUTI) on the third day of their hospital stay. What is the correct Present on Admission (POA) indicator for this diagnosis?

1. Y (Yes, present on admission)
2. N (No, not present on admission)
3. U (Unknown, documentation insufficient)
4. W (Clinically undetermined)

Answer: B. N (No, not present on admission)

Explanation:

The correct answer is N. A catheter-associated urinary tract infection that appears on the third day of the stay was not present when the inpatient order was written, so the POA indicator is N, meaning not present on admission.

Y is wrong because it applies only to conditions present at the time of the inpatient admission order, including conditions that started in the emergency department. U is wrong because it is reserved for cases where the documentation is insufficient to decide, and here the timing is clear. W is wrong because it is for situations where the provider cannot clinically determine whether the condition was present on admission, which is also not the case.

Rule to remember: pick the POA indicator from the documented timing. A condition that clearly develops after admission is N, and this matters because hospital-acquired conditions are tracked through these indicators.

Example 3

Question: Which Present on Admission (POA) indicator is assigned when documentation is insufficient to determine if a condition was present at the time of inpatient admission?

1. Y
2. N
3. U
4. W

Answer: C. U

Explanation:

The correct answer is U. The POA indicator U is used when the record does not give enough information to tell whether the condition was present at the time of inpatient admission. The usual next step is to query the provider rather than guess.

Y is wrong because it requires that the condition was present on admission, and the documentation does not show that. N is wrong because it requires that the condition was not present, which the documentation also does not show. W is wrong because it is for the case where the provider has reviewed the record and documents that the timing cannot be clinically determined. That is a clinical judgment, not a gap in the record.

Rule to remember: U means the documentation is missing, while W means the provider has said the answer cannot be known. When timing is unclear, ask a compliant, non-leading query before settling on either.

How to use these practice tests

Start with the ACDIS candidate handbook so you know the format, eligibility and scoring rules, then use our practice sets to find where you are weak.

1. Take a mixed set first, such as CDI Strategies or Clinical Coding, and note every miss by topic instead of by score.
2. Work through your weakest topics one at a time. Good starting points are Compliant Query Formulation, POA and Hospital-Acquired Conditions and Sepsis Criteria and Documentation.
3. For each wrong answer, write down the rule behind it in your own words, and check that rule against the official coding guidelines or your facility policy. Our questions are written by us, not taken from the real exam, so use them to practise reasoning rather than to memorise answers.
4. Move on to clinical documentation areas such as Malnutrition, Respiratory Failure and Vents and Principal Procedure Selection and MS-DRG.
5. Close with a timed run through several sets in one sitting to practise your pacing for the 3 hour limit, then retake the sets you struggled with.

Book your exam once your results are steady, keeping in mind the 90 day scheduling window that starts when your name is submitted to Prometric.

• Topics: Diagnosis coding, procedure coding, code linkage
• Questions: ~30 questions

Sample CCDS - Certified Clinical Documentation Specialist Practice Questions

Try these questions from our free CCDS - Certified Clinical Documentation Specialist practice tests. The correct answer and an explanation follow each question.

1. What is the role of a Clinical Documentation Specialist (CDS) in relation to clinical coding?

   • A. To manage patient care directly
   • B. To ensure that clinical documentation supports accurate coding and billing
   • C. To handle administrative tasks unrelated to clinical documentation
   • D. To provide patient financial assistance

Answer: B. To ensure that clinical documentation supports accurate coding and billing

A Clinical Documentation Specialist (CDS) plays a vital role in ensuring that clinical documentation accurately and completely supports the clinical codes assigned for billing and data analysis. They review patient records to identify any gaps or inconsistencies that could lead to incorrect coding. By querying physicians for clarification, the CDS helps to ensure that the documentation reflects the true severity of illness and complexity of care, thereby optimizing coding accuracy and reimbursement.

Answer: B. To enhance the accuracy and completeness of clinical documentation

The role of a Clinical Documentation Specialist (CDS) in healthcare documentation is to enhance its accuracy and completeness. CDS professionals review patient records to identify opportunities for improvement in documentation, ensuring that it precisely reflects the patient's severity of illness, risk of mortality, and the services rendered. This ultimately supports appropriate coding, accurate reimbursement, and improved quality reporting.

Answer: B. BUN/Cr ratio >20:1 with rapid creatinine normalization after IV fluid resuscitation

A BUN-to-creatinine ratio >20:1 combined with prompt creatinine normalization following fluid administration is the hallmark clinical picture of pre-renal AKI due to volume depletion or reduced renal perfusion.

Answer: D. W

POA indicator 'W' is used when the documentation is insufficient AND it is clinically impossible to determine if the condition was present on admission.
