2026 ICD-10-CM Diagnosis Code I72.0

Approximate Synonyms

The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classification

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

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.

• 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.

• 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.

• Aorta

  the main trunk of the systemic arteries.

• Iliac Artery

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

MS-DRG Mapping for ICD-10-CM Code I72.0

Diagnosis-Related Groups (DRGs) are used to classify hospital cases for billing and healthcare management. They help standardize how hospitals and other providers are reimbursed for inpatient care. Patients are grouped based on their principal diagnosis into broader categories called Major Diagnostic Categories (MDCs).

Once assigned to a DRG, the hospital receives a set payment for the patient’s care, regardless of the actual services provided. This fixed rate is intended to cover the typical cost of treating patients within that group. The payment amount depends on the DRG's relative weight, which reflects the expected complexity and cost of care based on the severity of the patient’s condition.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V43.0 applicable from 10/01/2025 through 09/30/2026.

Convert I72.0 to ICD-9-CM

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

Patient Education

Aneurysms

An aneurysm is a bulge or "ballooning" in the wall of an artery. Arteries are blood vessels that carry oxygen-rich blood from the heart to other parts of the body. If an aneurysm grows large, it can burst and cause dangerous bleeding or even death.

Most aneurysms occur in the aorta, the main artery that runs from the heart through the chest and abdomen. Aneurysms also can happen in arteries in the brain, heart and other parts of the body. If an aneurysm in the brain bursts, it causes a stroke.

Aneurysms can develop and become large before causing any symptoms. Often doctors can stop aneurysms from bursting if they find and treat them early. They use imaging tests to find aneurysms. Often aneurysms are found by chance during tests done for other reasons. Medicines and surgery are the two main treatments for aneurysms.
