Other aneurysm (I72)

Browse all the diagnosis codes used for other aneurysm (i72). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Aneurysm - Pathological outpouching or sac-like dilatation in the wall of any blood vessel (ARTERIES or VEINS) or the heart (HEART ANEURYSM). It indicates a thin and weakened area in the wall which may later rupture. Aneurysms are classified by location, etiology, or other characteristics.

Aneurysm, Aortic Arch - An abnormal balloon- or sac-like dilatation in the wall of the AORTIC ARCH.

Aneurysm, Ascending Aorta - An abnormal balloon- or sac-like dilatation in the wall of the ASCENDING AORTA.

Aneurysm, False - Not an aneurysm but a well-defined collection of blood and CONNECTIVE TISSUE outside the wall of a blood vessel or the heart. It is the containment of a ruptured blood vessel or heart, such as sealing a rupture of the left ventricle. False aneurysm is formed by organized THROMBUS and HEMATOMA in surrounding tissue.

Aneurysm, Infected - Aneurysm due to growth of microorganisms in the arterial wall, or infection arising within preexisting arteriosclerotic aneurysms.

Aneurysm, Ruptured - The tearing or bursting of the weakened wall of the aneurysmal sac, usually heralded by sudden worsening pain. The great danger of a ruptured aneurysm is the large amount of blood spilling into the surrounding tissues and cavities, causing HEMORRHAGIC SHOCK.

Aorta - The main trunk of the systemic arteries.

Aortic Aneurysm - An abnormal balloon- or sac-like dilatation in the wall of AORTA.

Aortic Aneurysm, Abdominal - An abnormal balloon- or sac-like dilatation in the wall of the ABDOMINAL AORTA which gives rise to the visceral, the parietal, and the terminal (iliac) branches below the aortic hiatus at the diaphragm.

Aortic Aneurysm, Thoracic - An abnormal balloon- or sac-like dilatation in the wall of the THORACIC AORTA. This proximal descending portion of aorta gives rise to the visceral and the parietal branches above the aortic hiatus at the diaphragm.

Aortic Aneurysm, Thoracoabdominal - An abnormal balloon- or sac-like dilatation in the wall of ABDOMINAL AORTA at the aortic hiatus.

Aortic Dissection - A tear in the inner layer of the AORTA leading to interstitial HEMORRHAGE, and splitting (dissecting) of the aortic TUNICA MEDIA layer. It typically begins with a tear in the TUNICA INTIMA layer.

Aortic Root Aneurysm - An abnormal balloon- or sac-like dilatation in the wall of the AORTIC ROOT.

Aortic Rupture - The tearing or bursting of the wall along any portion of the AORTA, such as thoracic or abdominal. It may result from the rupture of an aneurysm or it may be due to TRAUMA.

Arteriovenous Fistula - An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.

Bone Cysts, Aneurysmal - Fibrous blood-filled cyst in the bone. Although benign it can be destructive causing deformity and fractures.

Coronary Aneurysm - Abnormal balloon- or sac-like dilatation in the wall of CORONARY VESSELS. Most coronary aneurysms are due to CORONARY ATHEROSCLEROSIS, and the rest are due to inflammatory diseases, such as KAWASAKI DISEASE.

Descending Thoracic Aortic Aneurysm - An abnormal balloon- or sac-like dilatation in the wall of the DESCENDING THORACIC AORTA.

Endovascular Aneurysm Repair - Endovascular surgery used to treat an AORTIC ANEURYSM. It involves implanting an endovascular stent graft around dilated vessel area reinforcing the wall and creating an artificial lumen through which blood can circulate bypassing aneurysm sac.

Heart Aneurysm - A localized bulging or dilatation in the muscle wall of a heart (MYOCARDIUM), usually in the LEFT VENTRICLE. Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture.

Iliac Aneurysm - Abnormal balloon- or sac-like dilatation in the wall of any one of the iliac arteries including the common, the internal, or the external ILIAC ARTERY.

Iliac Artery - Either of two large arteries originating from the abdominal aorta; they supply blood to the pelvis, abdominal wall and legs.

Intracranial Aneurysm - Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE. (From Adams et al., Principles of Neurology, 6th ed, p841)

Microaneurysm - Aneurysm of the MICROVASCULATURE. Charcot–Bouchard aneurysms are aneurysms of the brain vasculature which is a common cause of CEREBRAL HEMORRHAGE. Retinal microaneurysm is an early diagnostic sign of DIABETIC RETINOPATHY.

Popliteal Artery Aneurysm - An abnormal balloon- or sac-like dilatation in the wall of the POPLITEAL ARTERY located behind the KNEE JOINT.

Subarachnoid Hemorrhage - Bleeding into the intracranial or spinal SUBARACHNOID SPACE, most resulting from INTRACRANIAL ANEURYSM rupture. It can occur after traumatic injuries (SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurological deficits and reduced mental status.

Instructional Notations

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

• aneurysm (cirsoid) (false) (ruptured)

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
