What This Code Means

Moderate malnutrition due to inadequate protein and calories, less severe than the kwashiorkor/marasmus spectrum.

Coding Tips

• •Moderate malnutrition indicates the patient has some nutritional reserves remaining, unlike severe malnutrition
• •Document the BMI or weight-for-height measurements to support the moderate classification

Clinical Significance

Moderate protein-calorie malnutrition represents a significant nutritional deficit where the patient shows measurable loss of body weight and muscle mass but retains some nutritional reserves, distinguishing it from severe forms. This condition is commonly encountered in hospitalized elderly patients, those with chronic diseases, and patients recovering from surgery, and it increases the risk of infection, poor wound healing, and prolonged hospital stays.

Documentation Requirements

• ✓Documentation must include objective measures supporting moderate severity: body mass index between 16-16.9, unintentional weight loss of 5-10% over 3-6 months, albumin between 2.5-3.5 g/dL, or moderate muscle wasting on physical exam.
• ✓A validated nutritional screening tool score (such as Subjective Global Assessment rating B) strengthens documentation.
• ✓The provider must explicitly state the severity as moderate and document the underlying cause.
