ICD10 code of Moyamoya and ICD9 code

Moyamoya disease is a rare cerebrovascular disorder characterized by the progressive narrowing of the internal carotid arteries, leading to reduced blood flow to the brain. The ICD-10 code for Moyamoya disease is I67.5. This code falls under the category of "Other cerebrovascular diseases" (I67) which includes various non-aneurysmal vascular disorders affecting the brain. It is important to note that ICD-10 codes are used for medical classification and coding purposes, allowing healthcare professionals to accurately document and track specific diseases for statistical and billing purposes.

For ICD-9, the previous coding system, the specific code for Moyamoya disease was not available. However, it may have been classified under broader categories such as "Other and unspecified disorders of the circulatory system" (ICD-9 code 459) or "Other cerebrovascular disease" (ICD-9 code 437.5). It is worth mentioning that the transition from ICD-9 to ICD-10 occurred in 2015, with ICD-10 providing more detailed and specific codes for improved accuracy in disease classification.
