I63.9

Cerebral infarction, unspecified

A disorder characterized by a sudden loss of sensory function due to an intracranial vascular event.

A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to brain ischemia or intracranial hemorrhages. Stroke is classified by the type of tissue necrosis, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. Non-hemorrhagic nature. from Adams et al., Principles of Neurology, 6th ed, pp777-810)

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. “mini-strokes” or transient ischemic attacks tias), occur when the blood supply to the brain is briefly interrupted.symptoms of stroke are

A sudden loss of neurological function secondary to hemorrhage or ischemia in the brain parenchyma due to a vascular event. Infarction or hemorrhage may be demonstrated either directly by imaging, laboratory, or pathologic examination in patients with symptom duration less than 24 hours, or inferred by symptoms lasting greater than or equal to 24 hours or fatal within 24 hours) that cannot be attributed to another cause. Diagnostic tests include ct scan, mri, angiography, and eeg to locate and evaluate the extent of the hemorrhagic or ischemic damage in the brain parenchyma, coagulation studies, complete blood count, comprehensive metabolic panel, and urinalysis.

An ischemic condition of the brain, producing a persistent focal neurological deficit in the area of distribution of the cerebral arteries.

In medicine, a loss of blood flow to part of the brain, which damages brain tissue. Strokes are caused by blood clots and broken blood vessels in the brain. Symptoms include dizziness, numbness, weakness on one side of the body, and problems with talking, writing, or understanding language. The risk of stroke is increased by high blood pressure, older age, smoking, diabetes, high cholesterol, heart disease, atherosclerosis a build-up of fatty material and plaque inside the coronary arteries), and a family history of stroke.

Sudden neurologic impairment due to a cerebrovascular disorder, either an arterial occlusion or an intracranial hemorrhage.

The formation of an area of necrosis in the cerebrum caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere i.e., left vs. Right), lobe e.g., frontal lobe infarction), arterial distribution e.g., infarction, anterior cerebral artery), and etiology e.g., embolic infarction).

I63.9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.

This is the American ICD-10-CM version of I63.9 – other international versions of ICD-10 I63.9 may differ.
