E53 vs E64.8
E53 (Deficiency of other B group vitamins) compared with E64.8 (Sequelae of other nutritional deficiencies), 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. E53 carries an Excludes1 note covering E64.8: “sequelae of vitamin B deficiency (E64.8)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
