ICD-10 code for glucose transport disorder

The ICD-10-CM code for glucose transport disorder is E74.819 (Disorders of glucose transport, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on E74.819.

Within E74.81, choose E74.819 (Disorders of glucose transport, unspecified) only when documentation doesn't support a more specific option: glucose transporter protein type 1 deficiency (E74.810) and other disorders of glucose transport (E74.818).

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.
