ICD-10 Code I67.7 – Cerebral arteritis, not elsewhere classified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I67.7 – Cerebral arteritis, not elsewhere classified
What it is
I67.7 identifies inflammation of the arteries in the brain that is not classified elsewhere. Use it when documentation specifically states cerebral arteritis and does not provide a more specific cause or subtype.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe neurologic symptoms related to cerebral vessel inflammation, such as headache, focal deficits, or stroke-like findings, but the record should support the diagnosis.
When to use this code
Use I67.7 when the provider documents cerebral arteritis and the condition is not better described by another code. This code may fit imaging, biopsy, or specialist notes that confirm arteritis affecting cerebral vessels. If the cause is specified, code that more exact diagnosis instead.
Do not use for
Do not use this code for generalized vasculitis, arteritis in other body sites, or nonspecific cerebrovascular symptoms alone. Check documentation if the note only mentions suspected inflammation without confirmation.
Coding tip
Code from the provider’s exact wording and look for any stated underlying vasculitis or systemic disease.
