ICD-10 Code E74 – Other disorders of carbohydrate metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E74 – Other disorders of carbohydrate metabolism
What it is
E74 covers inherited or acquired disorders that affect how the body processes carbohydrates. Use it when the record describes a carbohydrate metabolism disorder that is not named by a more specific ICD-10-CM code.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note poor carbohydrate tolerance, recurrent metabolic symptoms, or abnormal findings suggesting an enzyme-related metabolic disorder.
When to use this code
Use E74 when the provider documents a disorder of carbohydrate metabolism and no more specific diagnosis is available. It is also appropriate when the chart identifies a broader carbohydrate metabolism abnormality without naming the exact condition. Check documentation if the diagnosis is uncertain.
Do not use for
Do not use this code when a more specific carbohydrate metabolism diagnosis is documented, such as a named glycogen storage or disaccharide metabolism disorder. Do not use it for diabetes mellitus or nonspecific digestive intolerance.
Coding tip
Look for the exact metabolic diagnosis in the assessment, because E74 is a category code and should be reported only when specificity is lacking.
