Other specified disorders of carbohydrate transport and metabolism

This code encompasses various rare or less common inherited or acquired conditions affecting the body's ability to transport or metabolize carbohydrates, excluding diabetes mellitus and specific glycogen storage diseases. These disorders can lead to an accumulation of certain sugars or their byproducts, or a deficiency in essential carbohydrates, impacting multiple organ systems.

Use this code for diagnoses such as essential fructosuria, renal glycosuria, or other specified disorders of carbohydrate metabolism not classified elsewhere. Documentation should clearly state the specific carbohydrate transport or metabolic defect identified, often through genetic testing or specialized metabolic panels.

• Ensure the documentation specifies a carbohydrate disorder that doesn't fit into more specific ICD-9 codes like diabetes or a named glycogen storage disease.
• Avoid using this code if a more precise ICD-9 code for a specific carbohydrate disorder (e.g., galactosemia, lactose intolerance) is available.
• Always review the physician's notes for definitive diagnostic statements and supporting lab results to justify the use of this "other specified" code.
