Carotid stenosis is a narrowing or constriction of the inner surface (lumen) of the carotid artery, usually caused by atherosclerosis.
DRG Group #067-068 - Nonspecific cva and precerebral occlusion without infarct with MCC.
This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code I65.23 and a single ICD9 code, 433.10 is an approximate match for comparison and conversion purposes.
I65.29 is a billable diagnosis code used to specify a medical diagnosis of occlusion and stenosis of unspecified carotid artery. The code I65.29 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.#N#The ICD-10-CM code I65.29 might also be used to specify conditions or terms like 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, etc.#N#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.
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.".
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.
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.
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.

Carotid artery disease is a vague diagnosis and without further clarification from the physician is coded to I77.9 (Disorder of arteries and arterioles, unspecified) at this time. Once diagnosed the goal is to prevent further progression and stroke. Interesting fact: did you know that if you stop smoking the stroke risk is reduced to that of someone who doesn’t smoke within just a few years?
When a patient develops carotid artery disease, the arteries become narrowed due to fatty substances, calcium and other cellular waste products inside the lining of the artery. This can be further detailed as “stenosis” or “atherosclerosis.”. Atherosclerosis is the most common cause, but it is not the sole cause of the disease.
Prevention and Treatments (to help prevent stroke) 1 STOP smoking 2 Lose weight 3 Eat healthier foods 4 Increase physical activity/exercise 5 Keep other chronic conditions under control (hypertension, diabetes, etc.) 6 Medications (aspirin or antiplatelet medication such as Clopidogrel) 7 Keep your regular doctor appointments 8 Managing the stress in your life 9 Surgical treatments for severe cases including carotid endarterectomy and carotid angioplasty and stenting
When the coder indexes stenosis, carotid the index states “See occlusion carotid.” The coder can see that “with” is linking the cerebral infarction with carotid stenosis in the index:
When the coder indexes infarction, cerebral, there is the term “due to” listed.This means there must be a link by the physician documented. “Due to” is not assumed to exist without physician documentation.
Includes: occlusion and stenosis of cerebral and precerebral arteries, resulting in cerebral infarction#N#This note is including both occlusion AND stenosis causing cerebral infarction.
In reviewing the case from 3Q2018 Coding Clinic page 5, the MI is not coded as associated with a totally occluded coronary artery because the MI is in a different artery. The MI is coded separately from the total occlusion and is not assumed to be related.
