CDIP Clinical Validation Principles 3 — Questions and Answers
Question 1: In clinical validation, what is the primary distinction between a 'compliant query' and a 'leading query'?
- A compliant query suggests the preferred diagnosis; a leading query does not
- A compliant query presents clinical findings without suggesting the answer; a leading query steers the physician toward a specific diagnosis (Correct answer)
- A leading query is always verbal; a compliant query is always written
- There is no meaningful distinction between the two types
Correct answer: A compliant query presents clinical findings without suggesting the answer; a leading query steers the physician toward a specific diagnosis
AHIMA and ACDIS guidelines require queries to be non-leading, presenting objective clinical findings so physicians can exercise independent judgment.
Question 2: A patient is admitted with pneumonia and develops a secondary diagnosis of acute respiratory failure requiring mechanical ventilation. Which clinical validation consideration is most critical for coding?
- Whether pneumonia was present on admission
- Whether clinical indicators (PaO2/FiO2 ratio, respiratory rate, work of breathing) support acute respiratory failure (Correct answer)
- Whether the patient had prior respiratory conditions
- Whether the attending or pulmonologist documented the diagnosis
Correct answer: Whether clinical indicators (PaO2/FiO2 ratio, respiratory rate, work of breathing) support acute respiratory failure
Clinical indicators such as PaO2/FiO2 ratio, oxygen requirements, and work of breathing must be present to clinically validate an acute respiratory failure diagnosis.
Question 3: Under the UHDDS (Uniform Hospital Discharge Data Set), what defines a condition that qualifies as a secondary diagnosis?
- Any condition the physician documents in any note during the stay
- A condition that affects patient care in terms of requiring clinical evaluation, therapeutic treatment, diagnostic procedures, extended length of stay, or increased nursing care (Correct answer)
- Any chronic condition present in the patient's past medical history
- A condition diagnosed after discharge on the final coding review
Correct answer: A condition that affects patient care in terms of requiring clinical evaluation, therapeutic treatment, diagnostic procedures, extended length of stay, or increased nursing care
UHDDS guidelines specify that secondary diagnoses must affect patient care in at least one of five defined ways to be reported.
Question 4: A CDI specialist reviews a case where the physician documents 'possible heart failure' but the patient received no diuretics, BNP is normal, and echo shows normal EF. What is the most appropriate CDI action?
- Code heart failure as confirmed since the physician documented it
- Issue a clinical validation query asking the physician to confirm or clarify the heart failure diagnosis given the clinical picture (Correct answer)
- Delete the diagnosis from the record
- Request a cardiology consult to override the attending's documentation
Correct answer: Issue a clinical validation query asking the physician to confirm or clarify the heart failure diagnosis given the clinical picture
When clinical indicators do not support a documented diagnosis, a clinical validation query is appropriate to seek physician clarification.
Question 5: Which of the following best supports clinical validation of a Stage 3 pressure injury diagnosis?
- A nurse's note stating 'skin breakdown noted'
- Wound care documentation describing full-thickness tissue loss with visible subcutaneous fat but no exposed bone, tendon, or muscle (Correct answer)
- A physician order for wound care dressings
- An ICD-10 code assigned by the previous coder
Correct answer: Wound care documentation describing full-thickness tissue loss with visible subcutaneous fat but no exposed bone, tendon, or muscle
Stage 3 pressure injuries are defined by full-thickness tissue loss with subcutaneous fat visible but no exposed deeper structures, requiring wound documentation that matches this description.
Question 6: When a CDI professional challenges a diagnosis using clinical validation principles, what is the governing standard for their review?
- The CDI professional's personal clinical experience as a former nurse
- Nationally recognized clinical criteria, evidence-based medicine, and medical record documentation standards (Correct answer)
- The payer's clinical criteria for coverage determination
- The CDI software vendor's proprietary algorithm
Correct answer: Nationally recognized clinical criteria, evidence-based medicine, and medical record documentation standards
Clinical validation must be grounded in nationally recognized clinical criteria and evidence-based standards, not individual opinion, payer criteria, or proprietary tools.
Question 7: A physician documents 'encephalopathy' without further specification. The clinical record shows altered mental status, asterixis, and elevated ammonia in a patient with cirrhosis. What type of encephalopathy is best supported?
- Hypertensive encephalopathy
- Hepatic encephalopathy (Correct answer)
- Anoxic encephalopathy
- Toxic encephalopathy due to medications
Correct answer: Hepatic encephalopathy
Elevated ammonia, asterixis, altered mental status, and underlying cirrhosis collectively support hepatic encephalopathy as the most clinically justified specification.
