ICD-10 Code E74.3 – Other disorders of intestinal carbohydrate absorption (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E74.3 – Other disorders of intestinal carbohydrate absorption
What it is
E74.3 identifies disorders where the intestine does not properly absorb certain carbohydrates. Use it for documented carbohydrate malabsorption that is not classified elsewhere.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include abdominal bloating, gas, diarrhea, and symptoms that worsen after carbohydrate intake.
When to use this code
Use E74.3 when the record states a diagnosis of intestinal carbohydrate absorption disorder, carbohydrate malabsorption, or a similar documented condition. It may apply after evaluation for persistent gastrointestinal symptoms linked to specific sugars. Code it only when the provider clearly identifies this disorder.
Do not use for
Do not use this code for nonspecific abdominal pain, diarrhea, or food intolerance without a documented malabsorption diagnosis. Check documentation if the condition is instead due to another gastrointestinal disorder.
Coding tip
Confirm the provider documents malabsorption of carbohydrates, not just dietary intolerance or suspected sensitivity.
