About E71.12

E71.12 is the ICD-10-CM diagnosis code for disorders of propionate metabolism. It belongs to category E71 (disorders of branched-chain amino-acid metabolism and fatty-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 3 subcodes must be used instead.

Within E71.1 (other disorders of branched-chain amino-acid metabolism), E71.12 is specifically for disorders of propionate metabolism. Related codes cover branched-chain organic acidurias (E71.11) and other disorders of branched-chain amino-acid metabolism (E71.19).

To report this condition, pick the subcode that matches the documentation: E71.120 (acidemia), E71.121 (acidemia) and E71.128 (metabolism).

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