About E70

E70 is the ICD-10-CM diagnosis code for disorders of aromatic amino-acid metabolism. It belongs to block E70-E88 (metabolic disorders) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: E70.0 (phenylketonuria), E70.1 (hyperphenylalaninemias), E70.2 (metabolism), E70.3 (albinism), E70.4 (metabolism), E70.5 (metabolism), E70.8 (metabolism) and E70.9 (unspecified).

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