Occlusion and stenosis of unspecified posterior cerebral artery
ICD-10 I66.29 is a billable code used to indicate a diagnosis of occlusion and stenosis of unspecified posterior cerebral artery.
I66.29 refers to occlusion and stenosis of the unspecified posterior cerebral artery, which is a critical vessel supplying blood to the occipital lobe and parts of the temporal lobe of the brain. Clinical presentation may include symptoms such as visual disturbances, headaches, and neurological deficits, depending on the severity and duration of the occlusion. The anatomy involved includes the posterior cerebral artery (PCA), which branches from the basilar artery and is responsible for perfusing the posterior aspects of the cerebral hemispheres. Disease progression can lead to ischemic strokes if blood flow is significantly compromised, resulting in potential long-term neurological impairment. Diagnostic considerations include imaging studies such as MRI or CT angiography to visualize the occlusion or stenosis and assess collateral circulation. A thorough patient history and physical examination are essential to differentiate I66.29 from other cerebrovascular conditions, ensuring accurate diagnosis and treatment planning.

I66.29 encompasses occlusion and stenosis of the posterior cerebral artery that is not specified as right or left. This includes conditions that may lead to ischemic events affecting the posterior circulation of the brain.
I66.29 should be used when the occlusion or stenosis of the posterior cerebral artery is documented but not specified as affecting the right or left artery. If laterality is known, the corresponding specific code should be used.
Documentation should include clinical findings, imaging results confirming the occlusion or stenosis, and any relevant patient history that supports the diagnosis. Detailed notes on symptoms and treatment plans are also essential.
