ICD-10 Code E74.818 – Other disorders of glucose transport (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E74.818 – Other disorders of glucose transport
What it is
E74.818 identifies a disorder affecting the body’s transport of glucose. Use it when the record documents an inherited or other glucose transport problem that does not fit a more specific ICD-10-CM code.
Clinical signs
Clinical features vary; refer to documentation. Patients may have findings related to impaired glucose handling, but the exact presentation depends on the specific transport defect and associated condition.
When to use this code
Use this code when the provider documents a disorder of glucose transport and no more specific diagnosis is available. It is appropriate for nonspecific or “other” glucose transport disorders in the chart. If the record names a defined metabolic disorder, code that condition instead.
Do not use for
Do not use this code for diabetes mellitus, hypoglycemia, or other glucose abnormalities that are separately documented. Check documentation if the note describes a different inherited metabolic disorder.
Coding tip
Look for the exact wording “glucose transport disorder” and code the most specific diagnosis documented.
