Cerebral amyloid angiopathy
ICD-10 I68.0 is a billable code used to indicate a diagnosis of cerebral amyloid angiopathy.
Cerebral amyloid angiopathy (CAA) is a condition characterized by the accumulation of amyloid protein in the walls of the cerebral blood vessels, leading to vascular fragility and an increased risk of hemorrhagic strokes. Clinically, patients may present with recurrent lobar hemorrhages, cognitive decline, and other neurological deficits. The condition primarily affects the small and medium-sized arteries in the brain, which can lead to significant complications such as intracerebral hemorrhage. Disease progression can vary, with some individuals remaining asymptomatic for years while others may experience rapid cognitive decline or recurrent strokes. Diagnostic considerations include neuroimaging techniques such as MRI, which can reveal characteristic findings such as microbleeds and cortical superficial siderosis. A definitive diagnosis often requires a combination of clinical assessment and imaging studies, as well as ruling out other causes of hemorrhagic strokes. Understanding the pathophysiology of CAA is crucial for effective management, as it can significantly impact treatment decisions and patient outcomes.

I68.0 specifically covers cerebral amyloid angiopathy, which may lead to conditions such as lobar hemorrhages and cognitive impairment. It is crucial to differentiate it from other forms of vascular dementia and hemorrhagic strokes.
I68.0 should be used when there is clear evidence of amyloid deposition in the cerebral vessels, particularly when imaging shows characteristic findings. It is important to differentiate it from other hemorrhagic conditions such as I61, which does not involve amyloid pathology.
Documentation should include a detailed clinical history, neurological examination findings, and imaging results (preferably MRI) that demonstrate the presence of amyloid-related changes in the cerebral vasculature.
