E74.8Other specified disorders of carbohydrate metabolism

E74.8 is the ICD-10-CM diagnosis code for other specified disorders of carbohydrate metabolism. It belongs to category E74 (other disorders of carbohydrate 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 E74, choose E74.8 (Other specified disorders of carbohydrate metabolism) only when documentation doesn't support a more specific option: glycogen storage disease (E74.0), disorders of fructose metabolism (E74.1), disorders of galactose metabolism (E74.2), other disorders of intestinal carbohydrate absorption (E74.3), disorders of pyruvate metabolism and gluconeogenesis (E74.4) and disorder of carbohydrate metabolism, unspecified (E74.9).

To report this condition, pick the subcode that matches the documentation: E74.81 (classified), E74.82 (metabolism) and E74.89 (metabolism).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2021 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 271.4 (renal glycosuria) and 271.8 (other specified disorders of carbohydrate transport and metabolism).
