Valid for Submission
I74.9 is a billable diagnosis code used to specify a medical diagnosis of embolism and thrombosis of unspecified artery. The code I74.9 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 I74.9 might also be used to specify conditions or terms like arterial embolism, arterial embolus and thrombosis, arterial insufficiency of flap, arterial obstruction due to thrombotic embolism from aneurysm of artery, arterial obstruction due to thrombotic embolism from mural thrombus of heart , arterial thrombosis, etc.
Unspecified diagnosis codes like I74.9 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.

Information for Patients
What is a blood clot?
A blood clot is mass of blood that forms when platelets, proteins, and cells in the blood stick together. When you get hurt, your body forms a blood clot to stop the bleeding. After the bleeding stops and healing takes place, your body usually breaks down and removes the blood clot. But sometimes the blood clots form where they shouldn't, your body makes too many blood clots or abnormal blood clots, or the blood clots don't break down like they should. These blood clots can be dangerous and may cause other health problems.
Blood clots can form in, or travel to, the blood vessels in the limbs, lungs, brain, heart, and kidneys. The types of problems blood clots can cause will depend on where they are:
- Deep vein thrombosis (DVT) is a blood clot in a deep vein, usually in the lower leg, thigh, or pelvis. It can block a vein and cause damage to your leg.
- A pulmonary embolism can happen when a DVT breaks off and travels through the bloodstream to the lungs. It can damage your lungs and prevent your other organs from getting enough oxygen.
- Cerebral venous sinus thrombosis (CVST) is a rare blood clot in the venous sinuses in your brain. Normally the venous sinuses drain blood from your brain. CVST blocks the blood from draining and can cause a hemorrhagic stroke.
- Blood clots in other parts of the body can cause problems such as an ischemic stroke, a heart attack, kidney problems, kidney failure, and pregnancy-related problems.
Who is at risk for blood clots?
Certain factors can raise the risk of blood clots:
- Atrial fibrillation
- Cancer and cancer treatments
- Certain genetic disorders
- Certain surgeries
- Family history of blood clots
- Overweight and obesity
- Pregnancy and giving birth
- Serious injuries
- Some medicines, including birth control pills
- Staying in one position for a long time, such as being in the hospital or taking a long car or plane ride
What are the symptoms of blood clots?
The symptoms for blood clots can be different, depending on where the blood clot is:
- In the abdomen: Abdominal pain, nausea and vomiting
- In an arm or leg: Sudden or gradual pain, swelling, tenderness, and warmth
- In the lungs: Shortness of breath, pain with deep breathing, rapid breathing, and increased heart rate
- In the brain: Trouble speaking, vision problems, seizures, weakness on one side of the body, and sudden severe headache
- In the heart: Chest pain, sweating, shortness of breath, and pain in the left arm
How are blood clots diagnosed?
Your health care provider may use many tools to diagnose blood clots:
- A physical exam
- A medical history
- Blood tests, including a D-dimer test
- Imaging tests, such as
- X-rays of the veins (venography) or blood vessels (angiography) that are taken after you get an injection of special dye. The dye shows up on the x-ray and allows the provider to see how the blood flows.
- CT Scan
What are the treatments for blood clots?
Treatments for blood clots depend on where the blood clot is located and how severe it is. Treatments may include
- Blood thinners
- Other medicines, including thrombolytics. Thrombolytics are medicines which dissolve blood clots. They are usually used where the blood clots are severe.
- Surgery and other procedures to remove the blood clots
Can blood clots be prevented?
You may be able to help prevent blood clots by
- Moving around as soon as possible after having been confined to your bed, such as after surgery, illness, or injury
- Getting up and moving around every few hours when you have to sit for long periods of time, for example if you are on a long flight or car trip
- Regular physical activity
- Not smoking
- Staying at a healthy weight
Some people at high risk may need to take blood thinners to prevent blood clots.

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.
