The Basics of Abdominal Aortic Aneurysm
—The abdominal aorta is covered, anteriorly, by the lesser omentum and stomach, behind which are the branches of the celiac artery and the celiac plexus; below these, by the lienal vein, the pancreas, the left renal vein, the inferior part of the duodenum, the mesentery, and aortic plexus.
What Are the Signs and Symptoms of a Stomach Aneurysm?
The abdominal aorta runs from the diaphragm and ends just above the pelvis, where it divides into the iliac arteries. There are five arteries that branch from the abdominal aorta: the celiac artery, the superior mesenteric artery, the inferior mesenteric artery, the renal arteries and the iliac arteries.
The abdominal aorta is also known in medical Latin as the aorta abdominalis or the pars abdominalis aortae (under which it is often hidden in standard print medical dictionaries).
Your aorta is the large artery at the end of your heart's aortic valve. It carries oxygen-rich blood away from your heart to the rest of your body. It travels through your chest, where it's called the thoracic aorta, and into your abdomen, where it's called the abdominal aorta.
The aorta is the largest artery in the body and is the blood vessel that carries oxygen-rich blood away from the heart to all parts of the body. The section of the aorta that runs through the chest is called the thoracic aorta and, as the aorta moves down through the abdomen it is called the abdominal aorta.
The aorta is a large, cane-shaped vessel that delivers oxygen-rich blood to your body. It starts in the lower-left part of the heart and passes through the chest and abdomen.
The area in the back of the abdomen behind the peritoneum (the tissue that lines the abdominal wall and covers most of the organs in the abdomen). The organs in the retroperitoneum include the adrenal glands, aorta, kidneys, esophagus, ureters, pancreas, rectum, and parts of the stomach and colon.
Figure 1 summarises the arrangement of the branches of the abdominal aorta. The abdominal aorta has: Three single anterior visceral branches (coeliac, superior mesenteric artery, inferior mesenteric artery)
the celiac trunkThe first and often largest visceral branch of the abdominal aorta is the celiac trunk. The celiac trunk quickly bifurcates or trifurcates into branches.
ICD-10 code I71. 4 for Abdominal aortic aneurysm, without rupture is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
Instead of continuing upwards, the aorta then forms a curve called the aortic arch. By the end of that curve, the aorta is directed downwards. This portion is called the descending aorta. The descending aorta travels down the chest and becomes the abdominal aorta when it crosses the diaphragm.
The entire aorta divides into two parts: the thoracic aorta and the abdominal aorta. The ascending aorta, along with the aortic arch and the descending aorta, makes up the thoracic aorta.
While an aneurysm may occur in any blood vessel, but is most often seen in an artery, an abdominal aortic aneurysm (AAA) occurs in the wall of the aorta (the largest artery in the body) within the abdomen. A thoracic aortic aneurysm (TAA) occurs in the wall of the aorta within the chest.

Once in a lifetime abdominal aortic aneurysm (AAA) screening is only covered under certain specified conditions. When billing for AAA screenings, the following ICD-10 codes should be billed: * Z13.6 for the encounter for screening for cardiovascular disorders and either ** The most appropriate code for tobacco usage: Z87.891, F17.210, F17.211, F17.213, F17.218 and F17.219 OR * Z84.89 for family history of other specified conditions Note: CPT® code 76706 is the only ultrasound service that is payable for AAA screening under Medicare services.
Palmetto GBA acknowledges that no current ICD-10 diagnosis code specifically describes the circumstance “ (II) is a man age 65 to 75 who has smoked at least 100 cigarettes in his lifetime;” as noted in the CMS Internet-Only Manual, Publication 100-04, Medicare Claims Processing Manual, Chapter 18, Section 110.2 and 110.3.2.
