Clinical Significance

Unspecified disorder of tyrosine metabolism indicates a documented problem with how the body processes the amino acid tyrosine, but the specific type of disorder has not been identified. Tyrosine metabolism disorders can range from benign conditions to severe hepatorenal disease, making accurate diagnosis and specification essential for appropriate management and genetic counseling.

Documentation Requirements

• ✓Documentation should indicate the clinical findings suggesting tyrosine metabolism abnormality, including elevated tyrosine levels, urine organic acid analysis results, and any organ involvement (liver, kidneys, eyes, skin).
• ✓The provider should be queried for the specific type of tyrosine metabolism disorder to enable more precise coding.
• ✓Genetic testing results and family history should be documented when available.
