CCDS Malnutrition Diagnosis and Documentation 4 — Questions and Answers
Question 1: According to the 2012 ASPEN/A.S.P.E.N. consensus statement, which combination of findings is required to diagnose malnutrition?
- At least 2 of 6 defined diagnostic characteristics (Correct answer)
- Any single finding of weight loss or low BMI
- Albumin below 3.5 g/dL plus clinical judgment
- Three consecutive days of inadequate oral intake
Correct answer: At least 2 of 6 defined diagnostic characteristics
The ASPEN/A.S.P.E.N. consensus requires at least 2 of 6 characteristics: insufficient energy intake, weight loss, loss of muscle mass, loss of subcutaneous fat, fluid accumulation, and diminished functional status.
Question 2: A patient with chronic heart failure has significant bilateral lower extremity edema masking weight loss. How should the CDS address malnutrition documentation in this scenario?
- Query the physician to clarify whether malnutrition exists despite fluid masking true weight (Correct answer)
- Document malnutrition only after diuresis resolves the edema
- Use serum albumin as the sole diagnostic criterion in fluid-overloaded patients
- Avoid a malnutrition query because edema invalidates nutritional assessment
Correct answer: Query the physician to clarify whether malnutrition exists despite fluid masking true weight
Fluid accumulation can mask weight loss, so the CDS should query the physician to clarify the clinical picture rather than waiting for diuresis or relying on a single lab value.
Question 3: Under ICD-10-CM, which code correctly captures severe protein-calorie malnutrition?
- E41 – Nutritional marasmus (Correct answer)
- E44.0 – Moderate protein-calorie malnutrition
- E46 – Unspecified protein-calorie malnutrition
- Z72.4 – Inappropriate diet and eating habits
Correct answer: E41 – Nutritional marasmus
E41 (Nutritional marasmus) represents severe protein-calorie malnutrition characterized by severe wasting without edema, distinct from kwashiorkor (E40) and mixed (E42).
Question 4: A dietitian documents 'moderate malnutrition' in a nutrition note. What action should the CDS take?
- Query the attending physician to confirm and co-document the malnutrition diagnosis (Correct answer)
- Code the malnutrition directly from the dietitian's note without a physician query
- Disregard the dietitian note because only physicians may diagnose malnutrition
- Assign code E46 unspecified malnutrition until the physician weighs in
Correct answer: Query the attending physician to confirm and co-document the malnutrition diagnosis
Per coding guidelines, malnutrition diagnoses in dietitian notes require physician confirmation before the CDS can assign a code; a query to the attending is the appropriate next step.
Question 5: Which nutritional marker is LEAST reliable for diagnosing acute malnutrition because it is heavily influenced by inflammation?
- Serum albumin (Correct answer)
- Body weight trend over 30 days
- Grip strength measured by dynamometry
- Mid-upper arm circumference
Correct answer: Serum albumin
Serum albumin is a negative acute-phase reactant; inflammation drives it down independent of nutritional status, making it unreliable for diagnosing acute malnutrition.
Question 6: A patient loses 5% of body weight in 1 month due to inadequate oral intake post-surgery. Per ASPEN criteria, this weight loss severity is classified as:
- Moderate malnutrition (Correct answer)
- Mild malnutrition
- Severe malnutrition
- Risk for malnutrition only, not actual malnutrition
Correct answer: Moderate malnutrition
ASPEN criteria classify 5% weight loss in 1 month as moderate malnutrition when occurring in the context of acute illness or injury.
Question 7: Which documentation element most directly supports a 'severe malnutrition' designation under current ASPEN/Academy of Nutrition and Dietetics criteria?
- Energy intake less than 50% of estimated needs for more than 7 days (Correct answer)
- BMI between 18.5 and 20 with no other findings
- Mild muscle wasting in the absence of weight change
- Albumin of 3.2 g/dL with no inflammatory markers noted
Correct answer: Energy intake less than 50% of estimated needs for more than 7 days
Severe malnutrition in acute illness requires energy intake ≤50% of estimated needs for ≥5–7 days as one qualifying characteristic, along with at least one additional criterion.
