Cerebral infarction due to unspecified occlusion or stenosis of other precerebral arteries
ICD-10 I63.29 is a billable code used to indicate a diagnosis of cerebral infarction due to unspecified occlusion or stenosis of other precerebral arteries.
Cerebral infarction due to unspecified occlusion or stenosis of other precerebral arteries refers to a type of stroke that occurs when blood flow to a part of the brain is obstructed due to narrowing or blockage of arteries that supply blood to the brain, excluding the major arteries like the carotids. The clinical presentation may include sudden onset of neurological deficits such as weakness, numbness, difficulty speaking, or loss of coordination. The anatomy involved includes the precerebral arteries, which are smaller vessels branching from the carotid arteries and supplying blood to the brain. Disease progression can vary; some patients may experience transient ischemic attacks (TIAs) before a full stroke, while others may have a sudden and severe presentation. Diagnostic considerations include imaging studies like CT or MRI to identify the infarction and assess the extent of vascular occlusion. Risk factors include hypertension, diabetes, hyperlipidemia, and lifestyle factors such as smoking and obesity, which contribute to the development of atherosclerosis in these vessels.

I63.29 covers cerebral infarctions resulting from occlusion or stenosis of precerebral arteries that are not specified as carotid or vertebral. This includes various forms of ischemic strokes where the exact artery involved is not identified.
I63.29 should be used when the cerebral infarction is confirmed but the specific artery causing the occlusion or stenosis is not documented. If a specific artery is identified, a more specific code should be used.
Documentation should include a detailed clinical history, neurological examination findings, imaging studies (CT/MRI) showing the infarction, and any relevant lab results that support the diagnosis of cerebral infarction.
