Cerebral ischemia or brain ischemia, is a condition that occurs when there isn't enough blood flow to the brain to meet metabolic demand. This leads to limited oxygen supply or cerebral hypoxia and leads to the death of brain tissue, cerebral infarction, or ischemic stroke.

What is a transient episode?

Overview. A transient ischemic attack (TIA) is a brief episode during which parts of the brain do not receive enough blood. Because the blood supply is restored quickly, brain tissue does not die as it does in a stroke. These attacks are often early warning signs of a stroke, however.

What is transient cerebral ischemia?

Transient cerebral ischemia is defined as a temporary loss of blood flow to an area in the brain. In ICD-9-CM, codes for transient cerebral ischemia are classified under circulatory system diseases and are found in Chapter 7, Diseases of the Circulatory System. Conditions classified as transient cerebral ischemia are listed in category 435 and include basilar artery syndrome (435.0), vertebral artery syndrome (435.1), subclavian steal syndrome (435.2), and vertebro-basilar artery syndrome (435.3).

How do you know if you have cerebral ischemia?

Other symptoms will vary depending on the exact site of the cerebral ischemia and may include hemiparesis/hemiplegia (which may alternate from one side of the body to the other), speech disturbances (dysarthria, dysphonia, ...

What are the four parts of the vertebral arteries?

The vertebral arteries are divided into four parts, which include the prevertebral portion (V1), the cervical portion (V2), the atlantic or suboccipital portion (V3), and the intrancranial portion (V4). The basilar artery is formed by the right and left vertebral arteries, which unite in the base of the brain. The basilar artery joins with the internal carotid arteries at the base of the brain to form the circle of Willis. Together the vertebral and basilar arteries and their intracranial branches provide blood to the medulla, cerebellum, pons, midbrain, thalamus, and occipital cortex. Transient insufficiency of the vertebro-basilar blood supply results in symptoms and signs that are definitive for vertebro-basilar artery syndrome.

What is the ICd 9 code for basilar artery syndrome?

Again, these include 435.0 (basilar artery syndrome), 435.1 (vertebral artery syndrome), and 435.3 (vertebro-basilar artery syndrome). In ICD-10-CM, a single code, G45.0 Vertebro-basilar artery syndrome, covers the same conditions indicated by the three codes in ICD-9-CM. In order to understand why these conditions have been reclassified and combined into a single code in ICD-10-CM, it is necessary to review the medical terminology, anatomy, and pathophysiology related to these conditions.

What are the symptoms of a vertebral basilar artery?

The most common symptoms include dizziness/vertigo, nausea and vomiting, changes in the level of consciousness, and headache. Other symptoms will vary depending on the exact site of the cerebral ischemia and may include hemiparesis/hemiplegia (which may alternate from one side of the body to the other), speech disturbances (dysarthria, dysphonia, etc.), visual disturbances (blurred vision, double vision, nystagmus, pupillary changes, visual field defects, etc.), sensory changes (paresthesias in the face and scalp, disturbances affecting pain and temperature sensation), and gait changes (ataxia). While the duration of the ischemic attack will vary, the defining characteristic of this diagnosis is that the neurological symptoms and signs are transient in nature. A loss of blood supply to the vertebral or basilar arteries resulting in cerebral infarction would not be reported with code G45.0.

Why is the vertebrobasilar artery reclassified to the nervous system?

Because the vertebro-basilar arteries provide blood supply to the brain, the symptoms and signs associated with arterial insufficiency of these blood vessels are neurological in nature – this is the reason vertebro-basilar artery syndrome was reclassified to the nervous system chapter.

Vertebro-basilar artery syndrome results from transient insufficiency of vertebro-basilar artery blood flow. Because the vertebro-basilar arteries provide blood supply to the brain, the symptoms and signs associated with arterial insufficiency of these blood vessels are neurological in nature – this is the reason vertebro-basilar artery syndrome was reclassified to the nervous system chapter.
