Code Classification

  • Diseases of the circulatory system
    (I00–I99)
    • Cerebrovascular diseases
      (I60-I69)
      • Occlusion and stenosis of precerebral arteries, not resulting in cerebral infarction
        (I65)

I65.29 is a billable diagnosis code used to specify a medical diagnosis of occlusion and stenosis of unspecified carotid artery. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like I65.29 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Arteriosclerosis of carotid artery
  • Asymptomatic carotid artery stenosis
  • Asymptomatic occlusion of artery
  • Asymptomatic occlusion of artery
  • Asymptomatic occlusion of extracranial carotid artery
  • Asymptomatic occlusion of intracranial carotid artery
  • Asymptomatic stenosis of extracranial carotid artery
  • Asymptomatic stenosis of intracranial carotid artery
  • Carotid artery embolism
  • Carotid artery obstruction
  • Carotid artery occlusion
  • Carotid artery occlusion without infarction
  • Carotid artery stenosis
  • Carotid artery stenosis without infarction
  • Carotid artery thrombosis
  • Internal carotid artery stenosis
  • Occlusion of internal carotid artery
  • Symptomatic carotid artery stenosis
  • Thrombosis of internal carotid artery

Clinical Classification

Clinical Information

  • Carotid Artery Thrombosis

    blood clot formation in any part of the carotid arteries. this may produce carotid stenosis or occlusion of the vessel, leading to transient ischemic attack; cerebral infarction; or amaurosis fugax.

  • Carotid Artery Stenosis

    a narrowing of the carotid artery lumen. it is usually caused by the formation of an atherosclerotic plaque. symptoms are usually present when there is severe narrowing or obstruction of the arterial lumen and manifest as ischemic cerebrovascular accidents.

    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Carotid Artery Disease

Your carotid arteries are two large blood vessels in your neck. They supply your brain and head with blood. If you have carotid artery disease, the arteries become narrow or blocked, usually because of atherosclerosis. Atherosclerosis is the buildup of plaque, which is made up of fat, cholesterol, calcium, and other substances found in the blood.

Carotid artery disease is serious because it can block the blood flow to your brain, causing a stroke. Too much plaque in the artery can cause a blockage. You can also have a blockage when a piece of plaque or a blood clot breaks off the wall of an artery. The plaque or clot can travel through the bloodstream and get stuck in one of your brain's smaller arteries.

Carotid artery disease often does not cause symptoms until the blockage or narrowing is severe. One sign may be a bruit (whooshing sound) that your doctor hears when listening to your artery with a stethoscope. Another sign is a transient ischemic attack (TIA), a "mini-stroke." A TIA is like a stroke, but it only lasts a few minutes, and the symptoms usually go away within an hour. Stroke is another sign.

Imaging tests can confirm whether you have carotid artery disease.

Treatments may include:

  • Healthy lifestyle changes
  • Medicines
  • Carotid endarterectomy, surgery to remove the plaque
  • Angioplasty, a procedure to place a balloon and stent into the artery to open it and hold it open

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
