Valid for Submission
I63.213 is a billable diagnosis code used to specify a medical diagnosis of cerebral infarction due to unspecified occlusion or stenosis of bilateral vertebral arteries. The code I63.213 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code I63.213 might also be used to specify conditions or terms like cerebrovascular accident due to stenosis of bilateral vertebral arteries, cerebrovascular accident due to stenosis of left vertebral artery or cerebrovascular accident due to stenosis of right vertebral artery.
Unspecified diagnosis codes like I63.213 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Cerebrovascular accident due to stenosis of bilateral vertebral arteries
- Cerebrovascular accident due to stenosis of left vertebral artery
- Cerebrovascular accident due to stenosis of right vertebral artery
I63213 replaces the following previously assigned ICD-10 code(s):

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code I63.213 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
A stroke is a medical emergency. There are two types - ischemic and hemorrhagic. Ischemic stroke is the most common type. It is usually caused by a blood clot that blocks or plugs a blood vessel in the brain. This keeps blood from flowing to the brain. Within minutes, brain cells begin to die. Another cause is stenosis, or narrowing of the artery. This can happen because of atherosclerosis, a disease in which plaque builds up inside your arteries. Transient ischemic attacks (TIAs) occur when the blood supply to the brain is interrupted briefly. Having a TIA can mean you are at risk for having a more serious stroke.
Symptoms of stroke are
- Sudden numbness or weakness of the face, arm or leg (especially on one side of the body)
- Sudden confusion, trouble speaking or understanding speech
- Sudden trouble seeing in one or both eyes
- Sudden trouble walking, dizziness, loss of balance or coordination
- Sudden severe headache with no known cause
It is important to treat strokes as quickly as possible. Blood thinners may be used to stop a stroke while it is happening by quickly dissolving the blood clot. Post-stroke rehabilitation can help people overcome disabilities caused by stroke damage.
