G45.9 is a billable ICD code used to specify a diagnosis of transient cerebral ischemic attack, unspecified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
A transient ischemic attack (TIA) is a transient episode of neurologic dysfunction caused by ischemia (loss of blood flow) – either focal brain, spinal cord, or retinal – without acute infarction (tissue death).
This is follow up to a prior question: " ICD-9-CM Code 433.10 ";. TIA patients are frequently coded 433.10 at discharge; however, TIA patients are excluded from the stroke measure population. How should such cases be treated?

Coding Guidelines Residual neurological effects of a stroke or cerebrovascular accident (CVA) should be documented using CPT category I69 codes indicating sequelae of cerebrovascular disease. Codes I60-67 specify hemiplegia, hemiparesis, and monoplegia and identify whether the dominant or nondominant side is affected.
Having a TIA is a risk factor for eventually having a stroke or a silent stroke. Specialty: Neurology. MeSH Code: D002546. ICD 9 Code: 435.9. Source: Wikipedia.
Symptoms caused by a TIA resolve in 24 hours or less . TIAs cause the same symptoms associated with stroke, such as contralateral paralysis (opposite side of body from affected brain hemisphere) or sudden weakness or numbness.
A transient ischemic attack (TIA) is a transient episode of neurologic dysfunction caused by ischemia (loss of blood flow) – either focal brain, spinal cord, or retinal – without acute infarction (tissue death). TIAs have the same underlying cause as strokes: a disruption of cerebral blood flow ...
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.
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.
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.
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).
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.
The term “syndrome” refers to multiple symptoms and signs that together represent a specific condition, disease, or disease process. 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.
Together the vertebral and basilar arteries and their intracranial branches provide blood to the medulla, cerebellum, pons, midbrain, thalamus, and occipital cortex.

This is follow up to a prior question: " ICD-9-CM Code 433.10 ";. TIA patients are frequently coded 433.10 at discharge; however, TIA patients are excluded from the stroke measure population. How should such cases be treated?
Code 433.10 is an ischemic stroke code (Appendix A, Table 8.1, Specifications Manual for NHIQM, Version 3.0b) and included in the measure population if assigned as the ICD-9-CM principal diagnosis code at discharge. There are other codes for Transient Ischemic Attack.
