2021 ICD-10-CM Code I74.9
Embolism and thrombosis of unspecified artery
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 2021 from October 01, 2020 through September 30, 2021 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.

Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code I74.9 is grouped in the following groups for version MS-DRG V38.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2020 through 09/30/2021.

Information for Patients
Blood Clots
Also called: Hypercoagulability
Normally, if 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 clot. But some people get too many clots or their blood clots abnormally. Many conditions can cause the blood to clot too much or prevent blood clots from dissolving properly.
Risk factors for excessive blood clotting include
- Certain genetic disorders
- Atherosclerosis
- Diabetes
- Atrial fibrillation
- Overweight, obesity, and metabolic syndrome
- Some medicines
- Smoking
- Staying in one position for a long time, such as being in the hospital or taking a long car or plane ride
- Cancer and cancer treatments

Vascular Diseases
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
- Genetics
- Heart diseases such as high cholesterol and high blood pressure
- Infection
- Injury
- 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
- Obesity
- Pregnancy
- Sitting or standing still for long periods of time
- Smoking
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
- Surgery
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.
