What This Code Means

A metabolic disorder affecting amino acid processing in the body, but the specific type has not been identified or documented.

Coding Tips

  • This is a last-resort code; query the provider for more specific diagnostic information before coding
  • Do not use this code if any specific amino acid metabolism disorder can be identified from the medical record

Clinical Significance

Disorder of amino-acid metabolism, unspecified, is a last-resort code used when the provider has diagnosed an amino acid metabolism disorder but the specific type cannot be determined. This non-specific code should always trigger a query to the provider for additional diagnostic detail, as specificity impacts both clinical care and risk adjustment accuracy.

Documentation Requirements

  • Provider diagnosis of an amino acid metabolism disorder
  • Abnormal laboratory results indicating amino acid processing dysfunction
  • Documentation of why a more specific diagnosis has not been established
  • Clinical symptoms or findings prompting the diagnosis
  • Plan for additional diagnostic workup if the disorder is under investigation
