ICD-10 Code E74.19 – Other disorders of fructose metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E74.19 – Other disorders of fructose metabolism
What it is
E74.19 identifies a disorder in which the body cannot process fructose normally. Use it for documented fructose metabolism abnormalities that do not fit a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include symptoms after fructose intake, such as vomiting, abdominal pain, or hypoglycemia, but only when the record supports a fructose metabolism disorder.
When to use this code
Use this code when the provider documents an unspecified or other fructose metabolism disorder. It may apply when a genetic, hereditary, or metabolic evaluation identifies abnormal fructose handling, but the chart does not name a more specific condition.
Code it from the clinician’s diagnosis, not from diet intolerance alone. If the documentation only mentions fructose intolerance, poor diet tolerance, or nonspecific gastrointestinal symptoms, check documentation before assigning E74.19.
Do not use for
Do not use E74.19 for isolated fructose intolerance without a documented metabolic disorder. Do not substitute it for hereditary fructose intolerance or other specifically named inborn errors of metabolism.
Coding tip
Assign E74.19 only when the provider clearly documents an other or unspecified fructose metabolism disorder.
