About E63
E63 is the ICD-10-CM diagnosis code for 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 4 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: E63.0 (deficiency), E63.1 (intake), E63.8 (deficiencies) and E63.9 (unspecified).
The conditions in its Excludes2 note aren't part of E63, but may be coded alongside it if the patient has both: dehydration (E86.0), failure to thrive, adult (R62.7), failure to thrive, child (R62.51), feeding problems in newborn (P92.-) and 1 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
