Stenosis of peripheral vascular stent
The internal carotid artery is a terminal branch of the common carotid artery; it arises around the level of the fourth cervical vertebra when the common carotid bifurcates into this artery and its more superficial counterpart, the external carotid artery .
MeSH terms
I65. 2 - Occlusion and stenosis of carotid artery. ICD-10-CM.
Carotid artery stenosis is a narrowing of the large arteries on either side of the neck. These arteries carry blood to the head, face, and brain. This narrowing is usually the result of a build-up of plaque within the arteries, a condition called atherosclerosis.
Carotid stenosis occurs when plaque buildup begins blocking blood flow. Stenosis is a medical term for narrowing of blood vessels in the body due to a buildup of inflammatory substances and cholesterol deposits—called plaque. Two carotid arteries in the neck carry most of the blood flow from the heart to the brain.
Occlusion and stenosis of unspecified carotid artery I65. 29 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
The internal carotid arteries are branches of the common carotid arteries that bifurcate into the internal and external carotids at the level of the carotid sinus. [2] After this bifurcation, the internal carotids traverse through the base of the skull to reach the vital organs that they supply.
In the context of stroke, “stenosis” is usually caused by atherosclerosis, a condition where a blood vessel supplying blood to the brain is narrowed due to fatty deposits, known as plaques, on the vessel's inside wall. Risk factors for this type of stenosis include high blood pressure and high cholesterol.
Echo-lucent carotid plaques are lipid-rich and have a greater potential for clinical complications [7,10]. Heterogeneous plaques have a hypoechoic component and are associated with the presence of intra-plaque haemorrhage, ulceration and lipids, more likely to result in adverse events [8,21,22].
Carotid artery disease occurs when fatty deposits (plaques) clog the blood vessels that deliver blood to your brain and head (carotid arteries). The blockage increases your risk of stroke, a medical emergency that occurs when the blood supply to the brain is interrupted or seriously reduced.
Atherosclerosis causes most carotid artery disease. In this condition, fatty deposits build up along the inner layer of the arteries forming plaque. The thickening narrows the arteries and decreases blood flow or completely blocks the flow of blood to the brain.

Remember that a bilateral study which is not complete (i.e., limited) would be classified by CPT code 93882. For evaluation of carotid arteries, use CPT codes 93880, duplex scan of extracranial arteries, complete bilateral study or 93882, unilateral or limited study.
ICD-10 Codes That Support Medical Necessity and Covered by Medicare Program: Group 1 Paragraph: Extracranial Arteries Studies (93880-93882) Use a diagnosis code of R22. 1 (localized swelling, mass, and lump, neck) to report pulsatile neck mass.
