ICD-10 Code E74.8 – Other specified disorders of carbohydrate metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E74.8 – Other specified disorders of carbohydrate metabolism
What it is
E74.8 identifies a carbohydrate metabolism disorder that does not fit a more specific ICD-10 category. Use it when the record names a defined abnormality of carbohydrate processing, but not a listed subtype.
Clinical signs
Clinical features vary; refer to documentation. Findings may include symptoms or test results consistent with a carbohydrate metabolism disorder, but the chart should support the specific condition being described.
When to use this code
Use E74.8 when the provider documents an “other specified” carbohydrate metabolism disorder and no more specific code applies. It is appropriate when the diagnosis is established, but the exact named disorder is not separately indexed. Check documentation if the record is vague or incomplete.
Do not use for
Do not use this code for unspecified carbohydrate metabolism disorders or for conditions with a more precise ICD-10 code. If the note names a specific inherited or enzymatic disorder, code that diagnosis instead.
Coding tip
Look for the exact disorder name in the assessment and index it before defaulting to E74.8.
