E74.39Other disorders of intestinal carbohydrate absorption

E74.39 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within E74.3, choose E74.39 (Other disorders of intestinal carbohydrate absorption) only when documentation doesn't support a more specific option: Sucrase-isomaltase deficiency (E74.31).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), 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 has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 271.3 (intestinal disaccharidase deficiencies and disaccharide malabsorption).
