Other aneurysm (I72) ICD-10-CM
The I72 code range covers other aneurysm with 10 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the I72 range.
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
A minimally invasive surgical technique to repair aneurysms through the lumen of a blood vessel.
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.
About the I72 Code Range
The ICD-10 section I72 covers various types of aneurysms affecting arteries outside the heart and aorta, including those in the carotid, upper and lower extremities, renal, iliac, vertebral, and other uncommon arteries. These codes are used to specifically identify aneurysms in these less common arterial locations.
Each code under I72 helps healthcare professionals and coders accurately classify the site of an aneurysm, improving documentation and treatment planning. For example, I72.0 is the ICD-10 code for aneurysm of the carotid artery, also known by terms like "carotid artery aneurysm" or "aneurysm of the extracranial portion of the internal carotid artery." Similarly, I72.1 refers to aneurysms in the arteries of the upper extremity, including radial or brachial arteries, often called brachial artery or radial artery aneurysms. The section also includes codes for aneurysms of the renal artery (I72.2), iliac arteries (I72.3), and lower extremity arteries (I72.4), along with rarer sites like vertebral arteries (I72.6) and other specified arteries (I72.8). The code I72.9 represents aneurysms of unspecified artery sites, which is useful when the exact location is unknown. These specific ICD-10 codes ensure precise communication and proper care for vascular conditions affecting various peripheral and visceral arteries.
