E74.818 ICD-10-CM Code: Other disorders of glucose transport

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Inpatient Payment Groups (MS-DRG)

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0, Appendix B.

  • MS-DRG 642 — INBORN AND OTHER DISORDERS OF METABOLISM (MDC 10)

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Official Registry Overview & Definition

Other disorders of glucose transport is a billable ICD-10-CM diagnosis code (E74.818).

Official Tabular Instructional Notes

Sequencing, inclusion, and exclusion notes published for E74.818 in the official ICD-10-CM tabular list.

Inclusion Terms

Alternative terms the tabular list files under this code.

  • (Familial) renal glycosuria

Excludes1 — Not Coded Here

Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Excludes2 — Not Included Here

Conditions not covered by this code, but which may be reported alongside it when both are present.

Indexed Clinical Terms (5)

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code.

  • Deficiency, deficient, phosphomannomutase
  • Deficiency, deficient, phosphomannose isomerase
  • Deficiency, deficient, phosphomannosyl mutase
  • Disorder (of), glucose transport, specified NEC
  • Glycosuria, renal (familial)

Frequently Compared Codes

The official Excludes notes on E74.818 name these codes. Each comparison page covers when the two can — or must not — be reported together.

Potential MS-DRG Relationships (FY2026)

CC — Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 55 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 1 MS-DRG: DRG 642 (MDC 10).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
