ICD-10 Code E74.39 – Other disorders of intestinal carbohydrate absorption (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E74.39 – Other disorders of intestinal carbohydrate absorption
What it is
E74.39 identifies disorders in which the intestine does not absorb certain carbohydrates normally. Use it for documented carbohydrate malabsorption that does not fit a more specific ICD-10 code.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include abdominal bloating, gas, diarrhea, and discomfort after carbohydrate intake, but the record should support the specific malabsorption concern.
When to use this code
Use this code when the provider documents an intestinal carbohydrate absorption disorder and no more specific diagnosis is available. It may apply after evaluation for symptoms linked to carbohydrate intolerance or malabsorption. Code the documented condition, not the test alone.
Do not use for
Do not use E74.39 for lactose intolerance, hereditary fructose intolerance, or other more specific carbohydrate disorders when documented. Check documentation if the note only mentions nonspecific abdominal symptoms.
Coding tip
Match the code to the exact provider wording and avoid assigning it from symptoms alone.
