About E74.89

E74.89 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within E74.8, choose E74.89 (Other specified disorders of carbohydrate metabolism) only when documentation doesn't support a more specific option: disorders of glucose transport, not elsewhere classified (E74.81) and disorders of citrate metabolism (E74.82).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 642 (Inborn and Other Disorders of Metabolism, relative weight 1.3219), in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It was added in FY2021, effective October 1, 2020.
