Disorders of amino-acid transport, unspecified

This code signifies a metabolic disorder affecting the cellular transport mechanisms responsible for moving amino acids across membranes. It indicates a disruption in the body's ability to properly absorb, distribute, or excrete amino acids, without further specification of the particular transport defect. This can lead to an accumulation or deficiency of specific amino acids, potentially impacting various bodily functions.

Use this code when documentation indicates a diagnosed disorder of amino acid transport, but the specific type or affected amino acid is not identified. This may be appropriate for initial diagnoses or when diagnostic workup is incomplete. Supporting documentation would include physician notes mentioning "amino acid transport disorder, unspecified" or similar language.

• Avoid using this code if a more specific amino acid transport disorder (e.g., cystinuria, Hartnup disease) is documented.
• Always query the provider for greater specificity if possible, as more precise codes exist within the E72.0 subcategory.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
