About E74

E74 is the ICD-10-CM diagnosis code for other disorders of carbohydrate 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: E74.0 (disease), E74.1 (metabolism), E74.2 (metabolism), E74.3 (absorption), E74.4 (gluconeogenesis), E74.8 (metabolism) and E74.9 (unspecified).

Don't report E74 together with the conditions in its Excludes1 note: diabetes mellitus (E08-E13), hypoglycemia NOS (E16.2), increased secretion of glucagon (E16.3) and mucopolysaccharidosis (E76.0-E76.3).

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