ICD-10 Code E74.81 – Disorders of glucose transport, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E74.81 – Disorders of glucose transport, not elsewhere classified
What it is
E74.81 is used for a disorder affecting glucose transport, meaning glucose does not move normally across cell membranes. This is a metabolic condition, and the specific cause should be supported by documentation.
Clinical signs
Clinical features vary; refer to documentation. Findings may include signs of impaired glucose handling or a confirmed transporter defect, but you should not assume a diagnosis without provider support.
When to use this code
Use E74.81 when the record clearly documents a disorder of glucose transport and the provider has identified it as the diagnosis. It may also apply when a transporter-related metabolic disorder is stated without a more specific code. If the chart is unclear, check documentation before assigning it.
Do not use for
Do not use this code for diabetes mellitus, hypoglycemia, or nonspecific abnormal glucose tests. If the condition is described differently or more specifically, code the documented diagnosis instead.
Coding tip
Verify that the provider documents a glucose transport disorder, not just abnormal glucose results, before reporting E74.81.
