ICD10 code of Tyrosine Hydroxylase Deficiency and ICD9 code

Tyrosine hydroxylase deficiency is a rare genetic disorder that affects the production of certain neurotransmitters in the body. It is categorized under the umbrella term of "dopa-responsive dystonia." The ICD-10 code for tyrosine hydroxylase deficiency is E22.1. This code falls under the section for "Disorders of other endocrine glands" in the ICD-10 coding system.

In the previous ICD-9 coding system, tyrosine hydroxylase deficiency did not have a specific code. Instead, it would have been classified under a more general code for dystonia or other movement disorders. The closest relevant code in ICD-9 would have been 333.6, which refers to "Other secondary parkinsonism."

It is important to note that the ICD-10 code provides a more specific classification for tyrosine hydroxylase deficiency compared to the previous ICD-9 system. The ICD-10 coding system allows for more accurate and detailed documentation of medical conditions, which aids in research, epidemiology, and healthcare management.

If you suspect that you or someone you know may have tyrosine hydroxylase deficiency, it is essential to consult with a healthcare professional who can provide a proper diagnosis and guidance regarding treatment options.
