E74.3Other disorders of intestinal carbohydrate absorption

E74.3 is the ICD-10-CM diagnosis code for other disorders of intestinal carbohydrate absorption. 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 2 subcodes must be used instead.

Within E74, choose E74.3 (Other disorders of intestinal carbohydrate absorption) 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), disorders of pyruvate metabolism and gluconeogenesis (E74.4), other specified disorders of carbohydrate metabolism (E74.8) and disorder of carbohydrate metabolism, unspecified (E74.9).

To report this condition, pick the subcode that matches the documentation: E74.31 (deficiency) and E74.39 (absorption).

The conditions in its Excludes2 note aren't part of E74.3, but may be coded alongside it if the patient has both: lactose intolerance (E73.-).

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