Full Answer
Dissecting aortic aneurysm or aortic dissection is classified to ICD-9-CM code 441.0x. The following fifth-digit subclassifications identify the site of the dissection: • 441.03, Thoracoabdominal.
Type B Aortic Dissections: Current Guidelines for Treatment Stanford type B aortic dissections (TBADs) involve the descending aorta and can present with complications, including malperfusion syndrome or aortic rupture, which are associated with significant morbidity and mortality if left untreated.
The following fifth-digit subclassifications identify the site of the dissection: • 441.03, Thoracoabdominal. Aortic dissections may be classified as type A or B. Type A is defined as involving the ascending aorta and usually requires surgical treatment. Type B does not involve the ascending aorta and may be managed medically.
Short description: Dsct of thoracic aorta. ICD-9-CM 441.01 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 441.01 should only be used for claims with a date of service on or before September 30, 2015.
Aortic dissections are classified into two types: type B dissection involves a tear in the descending part of the aorta and may extend into the abdomen, whereas type A dissection develops in the ascending part of the aorta just as it branches off the heart.
In the Stanford classification of aortic dissection: Type A involves the ascending aorta and may progress to involve the arch and thoracoabdominal aorta. Type B involves the descending thoracic or thoracoabdominal aorta distal to the left subclavian artery without involvement of ascending aorta.
Type B aortic dissection originates in the descending aorta, which extends from the arch at the top of the ascending aorta—the part that extends upward from the heart—to the bottom section of the aorta, also known as the abdominal aorta.
I71ICD-10 code I71 for Aortic aneurysm and dissection is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
Uncomplicated type B aortic dissection is generally managed with optimal medical therapy, which includes pain control and strict blood pressure and heart rate control (also referred to as "anti-impulse therapy") [1].
By definition, type A dissection involves the ascending aorta, whereas type B dissection is limited to the aorta distal to the left subclavian artery (2). An earlier classification system, proposed by DeBakey et al (3), is used similarly to classify aortic dissections into ascending and descending types.
Background. Stanford type B aortic dissection is one of the aortic catastrophes with a high mortality and morbidity that needs immediate or delayed treatment, either surgically or endovascularly.
Type A which is the more common and dangerous of the two and involves a tear in the part of the aorta where it exits the heart or a tear in the upper, or ascending aorta, which may extend into the abdomen. Type B which involves a tear in the lower, or descending, aorta only, which may also extend into the abdomen.
An aortic aneurysm occurs when a weak spot in the wall of the aorta begins to bulge, as shown in the image on the left. An aneurysm can occur anywhere in the aorta. Having an aortic aneurysm increases the risk of a tear in the aortic lining (aortic dissection), as shown in the image on the right.

Thoracoabdominal aortic dissection (TAAD) is defined as separation of the layers of the tunica media by ingress of the blood, producing a false lumen (FL) with variable proximal or distal extension. It is not an infrequent clinical entity and constitute 40% of all dissections.
The ascending aorta is the beginning portion of the largest blood vessel in your body. It carries oxygen-rich blood from your heart to the rest of your aorta. Your two main coronary arteries branch off of the ascending aorta.
Aortic dissection is a serious condition and may be fatal if not treated early. The aorta is the body’s main artery, which branches off the heart and descends in the thorax and into the abdomen. A dissection of the aorta occurs when a tear develops within its wall. The wall consists of three layers and this tear allows blood to flow in between the inner and middle layers, causing them to separate (dissect). Aortic dissections are classified into two types: type B dissection involves a tear in the descending part of the aorta and may extend into the abdomen, whereas type A dissection develops in the ascending part of the aorta just as it branches off the heart.

In addition, the build-up of blood in the wall of the aorta can disrupt normal blood flow down the thorax and abdomen. This can compromise blood supply to organs such as the kidney and intestines. Go to:
This usually involves medications that decrease blood pressure and heart rate. By minimizing stress on the wall of the aorta, the dissection is less likely to worsen over time. Blood pressure lowering medication may need to be life-long in addition to regular CT or MRI scans to monitor any changes. Go to:
