Other disorders of intestinal carbohydrate absorption

This code represents a range of conditions where the small intestine is unable to properly absorb various carbohydrates, excluding specific disaccharidase deficiencies like lactase deficiency. Patients typically present with symptoms such as chronic diarrhea, abdominal pain, bloating, and malabsorption-related nutritional deficiencies. The underlying cause can be diverse, affecting different carbohydrate transport mechanisms.

Apply this code when documentation indicates a diagnosed disorder of intestinal carbohydrate absorption that is not specifically identified as a disaccharidase deficiency (e.g., lactose, sucrose, isomaltose) or glucose-galactose malabsorption. This diagnosis is often supported by breath tests, stool studies, or intestinal biopsies demonstrating impaired carbohydrate absorption.

• Do not use this code for documented lactase deficiency; instead, use E73.0.
• Ensure the documentation specifies "other" or "unspecified" carbohydrate malabsorption when a more specific code is not available.
• Consider sequencing this code after any underlying conditions causing the malabsorption, if applicable.
