ICD-10 Code I68.0 – Cerebral amyloid angiopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I68.0 – Cerebral amyloid angiopathy
What it is
I68.0 identifies cerebral amyloid angiopathy, a condition in which amyloid deposits weaken blood vessel walls in the brain. It is used when the diagnosis is documented and linked to cerebrovascular disease.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include lobar intracerebral hemorrhage, cerebral microbleeds, or recurrent bleeding in older adults, sometimes with cognitive changes.
When to use this code
Use I68.0 when the provider documents cerebral amyloid angiopathy as the cause or associated condition in a cerebrovascular disorder. It is appropriate when imaging, pathology, or specialist assessment supports the diagnosis. Code the documented cerebrovascular event separately if applicable.
Do not use for
Do not use this code for nonspecific brain hemorrhage without documented amyloid angiopathy. Check documentation if the record only mentions suspected, ruled-out, or unrelated amyloid disease.
Coding tip
Assign I68.0 only when the clinician clearly links amyloid angiopathy to the cerebrovascular condition.
