E70.20
ICD-10-CMThis code signifies an unspecific metabolic error involving tyrosine, an amino acid crucial for protein synthesis and neurotransmitter production. It indicates a disruption in the body's ability to properly process tyrosine, without further specification of the exact enzymatic defect or clinical manifestation.
Utilize this code when documentation indicates a diagnosed disorder of tyrosine metabolism but lacks the specificity to assign a more precise code (e.g., tyrosinemia type I, II, or III). This is appropriate when the physician's diagnosis explicitly states "disorder of tyrosine metabolism, unspecified" or similar vague terminology.
