Other disorders of fructose metabolism

This code signifies a rare genetic condition where the body has difficulty processing fructose, a sugar found in fruits and some vegetables. It encompasses various less common defects in fructose metabolism pathways beyond essential fructosuria and hereditary fructose intolerance. Patients may experience symptoms ranging from mild to severe, depending on the specific enzyme deficiency.

Use this code for documented diagnoses of fructose metabolism disorders that are not specifically identified as essential fructosuria (E74.11) or hereditary fructose intolerance (E74.12). This applies when the physician's documentation indicates a confirmed "other" or unspecified disorder of fructose metabolism, often following genetic testing or enzyme assays. Supporting documentation should clearly state the diagnosis and rule out more specific fructose metabolism disorders.

• Ensure documentation specifies a fructose metabolism disorder that is not E74.11 or E74.12.
• Avoid using this code if the documentation points to a more specific fructose metabolism disorder; query the provider for clarification.
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
