ICD10 code: I67.8 - Other cerebrovascular diseases in other diseases classified elsewhere
ICD9 code: 437.5 - Moyamoya disease
Cadasil, also known as Cerebral Autosomal Dominant Arteriopathy with Sub-Cortical Infarcts and Leukoencephalopathy, is classified under ICD10 code I67.8. In the older ICD9 system, it was classified as Moyamoya disease with the code 437.5. These codes are used for medical billing and coding purposes to identify and classify specific conditions for healthcare providers and insurance companies.
The ICD-10 code for Cadasil (Cerebral Autosomal Dominant Arteriopathy with Sub-Cortical Infarcts and Leukoencephalopathy) is I67.850. This code falls under the category of "Other cerebrovascular diseases" and specifically refers to non-atherosclerotic vascular disorders affecting the central nervous system. Cadasil is a hereditary condition that causes recurrent strokes and progressive cognitive decline due to the thickening and narrowing of small blood vessels in the brain.
In contrast, the ICD-9 code for Cadasil is 437.5, which is classified under "Other and ill-defined cerebrovascular disease." However, it is important to note that the ICD-9 code system has been replaced by ICD-10, which provides more detailed and specific coding options.
Please consult with a healthcare professional or medical coding specialist for accurate and up-to-date coding information, as they can provide the most current and comprehensive guidance based on the specific circumstances of the patient.
