About E44

E44 is the ICD-10-CM diagnosis code for protein-calorie malnutrition of moderate and mild degree. It belongs to block E40-E46 (malnutrition) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: E44.0 (malnutrition) and E44.1 (malnutrition).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
