Occlusion and stenosis of right carotid artery
ICD-10 I65.21 is a billable code used to indicate a diagnosis of occlusion and stenosis of right carotid artery.
I65.21 refers to the occlusion and stenosis of the right carotid artery, a condition characterized by the narrowing or blockage of the artery that supplies blood to the brain. This condition can lead to significant clinical presentations, including transient ischemic attacks (TIAs) or strokes, which may manifest as sudden weakness, speech difficulties, or visual disturbances. The right carotid artery, branching from the aorta, bifurcates into the internal and external carotid arteries, supplying blood to the brain and face. Disease progression often involves atherosclerosis, where fatty deposits build up in the arterial walls, leading to reduced blood flow. Diagnostic considerations include imaging studies such as carotid Doppler ultrasound, CT angiography, or MR angiography to assess the degree of stenosis. Early detection and management are crucial to prevent serious complications such as cerebrovascular accidents. Treatment may involve lifestyle modifications, medication, or surgical interventions like carotid endarterectomy or stenting, depending on the severity of the occlusion.

I65.21 covers occlusion and stenosis of the right carotid artery, which may result from atherosclerosis, thrombosis, or embolism. It is important to document the degree of stenosis and any associated symptoms, such as TIAs or strokes.
I65.21 should be used specifically when there is documented occlusion or stenosis of the right carotid artery. If the condition affects the left carotid artery, I65.22 should be used. Additionally, if there are symptoms of cerebrovascular events, appropriate codes for those conditions should also be considered.
Documentation supporting I65.21 should include clinical notes detailing the patient's symptoms, results from imaging studies confirming the occlusion or stenosis, and any treatment plans. It is essential to have a clear record of the patient's history and risk factors for cardiovascular disease.
