Cerebral arteritis in other diseases classified elsewhere

BILLABLE
Billable Code

Manifestation
Manifestation Code
Certain ICD-10-CM codes identify an underlying condition known as an etiology code. Conditions that arise as a result of an underlying condition (etiology), are referred to as Manifestations. In ICD-10-CM, etiology codes must be coded first, followed by the manifestation codes. When a condition requires etiology and manifestation codes, there is a "use additional code" note following the etiology code and a "code first" note following the manifestation code.

The ICD code I68 is used to code Cerebrovascular disease

Cerebrovascular disease, stroke or cerebrovascular accident, is a vascular disease of the cerebral circulation. Arteries supplying oxygen to the brain are affected resulting in one of a number of cerebrovascular diseases. Most commonly this is a stroke or mini-stroke and sometimes can be a hemorrhagic stroke. Any of these can result in vascular dementia.
