About E64

E64 is the ICD-10-CM diagnosis code for sequelae of malnutrition and other nutritional deficiencies. It belongs to block E50-E64 (other nutritional deficiencies) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: E64.0 (malnutrition), E64.1 (deficiency), E64.2 (deficiency), E64.3 (rickets), E64.8 (deficiencies) and E64.9 (deficiency).

Code first: condition resulting from (sequela) of malnutrition and other nutritional deficiencies.

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

The 'sequelae' include conditions specified as such; they also include the late effects of diseases classifiable to the above categories if the disease itself is no longer present
