E42 vs E64.0
E42 (Marasmic kwashiorkor) compared with E64.0 (Sequelae of protein-calorie malnutrition), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. E42 carries an Excludes1 note covering E64.0: “sequelae of protein-calorie malnutrition (E64.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
