If you look through the tabular in the Malnutrition it will become clear. Also it helps to understand general ICD-10-CM guidelines on specified vs unspecified

Malnutrition falls under the range E40-E46

E40 is Kwashiorkor which is subdefined in the I10 book as "Severe malnutrition with nutritional edema with dyspigmentation of skin and hair"

E41 is Nutritional marasmus which is subdefined in the I10 book as "Severe malnutrition with marasmus"

E42 is Marasmic kwashiorkor which is subdefined in the I10 book as "Intermediate form severe protein-calorie malnutrition" or "Severe protein-calorie malnutrition with signs of both kwashiorkor and marasmus"

E43 is Unspecified severe protein-calorie malnutrition means its documented as severe but documentation is not specific enough to assign E40-E42

E44.0 is Moderate protein-calorie malnutrition

E44.1 is mild protein-calorie malnutrition

E45 is Retarded development following protein-calorie malnutrition

E46 is Unspecified protein-calorie malnutrition AKA Malnutrition NOS meaning its not documented as Severe, Moderate or Low in the documentation so its not specific enough to assign E40-E45.
