About E71

E71 is the ICD-10-CM diagnosis code for disorders of branched-chain amino-acid metabolism and fatty-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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: E71.0 (disease), E71.1 (metabolism), E71.2 (unspecified), E71.3 (metabolism), E71.4 (metabolism) and E71.5 (disorders).

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