Valid for Submission
G46.2 is a billable diagnosis code used to specify a medical diagnosis of posterior cerebral artery syndrome. The code G46.2 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code G46.2 might also be used to specify conditions or terms like brain stem infarction, infarction of medulla oblongata, occipital cerebral infarction or posterior cerebral artery syndrome.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code G46.2 are found in the index:
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Brain stem infarction
- Infarction of medulla oblongata
- Occipital cerebral infarction
- Posterior cerebral artery syndrome
- INFARCTION POSTERIOR CEREBRAL ARTERY-. necrosis induced by ischemia in the posterior cerebral artery distribution system which supplies portions of the brain stem; the thalamus; temporal lobe and occipital lobe. depending on the size and location of infarction clinical features include olfaction disorders and visual problems agnosia; alexia; hemianopsia.
Convert G46.2 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code G46.2 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
The brain is the control center of the body. It controls thoughts, memory, speech, and movement. It regulates the function of many organs. When the brain is healthy, it works quickly and automatically. However, when problems occur, the results can be devastating.
Inflammation in the brain can lead to problems such as vision loss, weakness and paralysis. Loss of brain cells, which happens if you suffer a stroke, can affect your ability to think clearly. Brain tumors can also press on nerves and affect brain function. Some brain diseases are genetic. And we do not know what causes some brain diseases, such as Alzheimer's disease.
The symptoms of brain diseases vary widely depending on the specific problem. In some cases, damage is permanent. In other cases, treatments such as surgery, medicines, or physical therapy can correct the source of the problem or improve symptoms.

What are vascular diseases?
Your vascular system is your body's network of blood vessels. It includes your
- Arteries, which carry oxygen-rich blood from your heart to your tissues and organs
- Veins, which carry the blood and waste products back to your heart
- Capillaries, which are tiny blood vessels that connect your small arteries to your small veins. The walls of the capillaries are thin and leaky, to allow for an exchange of materials between your tissues and blood.
Vascular diseases are conditions which affect your vascular system. They are common and can be serious. Some types include
- Aneurysm - a bulge or "ballooning" in the wall of an artery
- Atherosclerosis - a disease in which plaque builds up inside your arteries. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood.
- Blood clots, including deep vein thrombosis and pulmonary embolism
- Coronary artery disease and carotid artery disease, diseases that involve the narrowing or blockage of an artery. The cause is usually a buildup of plaque.
- Raynaud's disease - a disorder that causes the blood vessels to narrow when you are cold or feeling stressed
- Stroke - a serious condition that happens when blood flow to your brain stops.
- Varicose veins - swollen, twisted veins that you can see just under the skin
- Vasculitis - inflammation of the blood vessels
What causes vascular diseases?
The causes of vascular diseases depend on the specific disease. These causes include
- Heart diseases such as high cholesterol and high blood pressure
- Medicines, including hormones
Sometimes the cause is unknown.
Who is at risk for vascular diseases?
The risk factors for vascular diseases can vary, depending on the specific disease. But some of the more common risk factors include
- Age - your risk of some diseases goes up as you get older
- Conditions that can affect the heart and blood vessels, such as diabetes or high cholesterol
- Family history of vascular or heart diseases
- Infection or injury that damages your veins
- Lack of exercise
- Sitting or standing still for long periods of time
What are the symptoms of vascular diseases?
The symptoms for each disease are different.
How are vascular diseases diagnosed?
To make a diagnosis, your health care provider will do a physical exam and ask about your symptoms and medical history. You may have imaging tests and/or blood tests.
How are vascular diseases treated?
Which treatment you get depends on which vascular disease you have and how severe it is. Types of treatments for vascular diseases include
- Lifestyle changes, such as eating a heart-healthy diet and getting more exercise
- Medicines, such as blood pressure medicines, blood thinners, cholesterol medicines, and clot-dissolving drugs. In some cases, providers use a catheter to send medicine directly to a blood vessel.
- Non-surgical procedures, such as angioplasty, stenting, and vein ablation
Can vascular diseases be prevented?
There are steps you can take to help prevent vascular diseases:
- Make healthy lifestyle changes, such as eating a heart-healthy diet and getting more exercise
- Don't smoke. If you are already a smoker, talk to your health care provider for help in finding the best way for you to quit.
- Keep your blood pressure and cholesterol in check
- If you have diabetes, control your blood sugar
- Try not to sit or stand for up long periods of time. If you do need to sit all day, get up and move around every hour or so. If you traveling on a long trip, you can also wear compression stockings and regularly stretch your legs.
