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.
