ICD-10 Code E74.819 – Disorders of glucose transport, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E74.819 – Disorders of glucose transport, unspecified
What it is
E74.819 identifies a disorder affecting normal glucose transport, but the specific type is not documented. Use it when the record confirms a glucose transport problem without further detail.
Clinical signs
Clinical features vary; refer to documentation. Findings may reflect impaired glucose handling, but you should code only when the provider documents a glucose transport disorder.
When to use this code
Use this code when the clinician documents a glucose transport disorder and does not specify a more exact diagnosis. It also fits when the chart mentions the condition but leaves the transport defect unspecified. If another inherited or metabolic disorder is named, check documentation before assigning E74.819.
Do not use for
Do not use it for diabetes mellitus, hypoglycemia, or other clearly documented carbohydrate metabolism disorders. If the record names a specific glucose transport defect, code the specified condition instead.
Coding tip
Query the provider when “glucose transport disorder” appears without detail, because unspecified coding should reflect the exact wording in the record.
