E72.8Other specified disorders of amino-acid metabolism

E72.8 is the ICD-10-CM diagnosis code for other specified disorders of amino-acid metabolism. It belongs to category E72 (other disorders of amino-acid metabolism), 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 2 subcodes must be used instead.

Within E72, choose E72.8 (Other specified disorders of amino-acid metabolism) only when documentation doesn't support a more specific option: disorders of amino-acid transport (E72.0), disorders of sulfur-bearing amino-acid metabolism (E72.1), disorders of urea cycle metabolism (E72.2), disorders of lysine and hydroxylysine metabolism (E72.3), disorders of ornithine metabolism (E72.4), disorders of glycine metabolism (E72.5) and disorder of amino-acid metabolism, unspecified (E72.9).

To report this condition, pick the subcode that matches the documentation: E72.81 (metabolism) and E72.89 (metabolism).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2019 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 270.7 (other disturbances of straight-chain amino-acid metabolism) and 270.8 (other specified disorders of amino-acid metabolism).
