Aortic aneurysm and dissection
Chapter 9:Diseases of the circulatory system
ICD-10 I71 is a used to indicate a diagnosis of aortic aneurysm and dissection.
I71 refers to aortic aneurysm and dissection, which are serious cardiovascular conditions characterized by the abnormal dilation (aneurysm) or tearing (dissection) of the aorta, the body's largest artery. Aortic aneurysms can occur in various segments of the aorta, including the thoracic and abdominal regions, and may be classified as either true or false aneurysms based on their anatomical characteristics. Clinical presentation often includes symptoms such as chest or back pain, a pulsating mass in the abdomen, or sudden onset of severe pain indicative of dissection. Disease progression can lead to life-threatening complications such as rupture, which necessitates immediate medical intervention. Diagnostic considerations include imaging studies such as ultrasound, CT scans, or MRI to confirm the presence and extent of the aneurysm or dissection. Early detection and management are crucial to prevent catastrophic outcomes, making awareness of risk factors such as hypertension, atherosclerosis, and genetic predispositions essential in clinical practice.

I71 encompasses various types of aortic aneurysms (thoracic and abdominal) and dissections. It includes conditions such as thoracic aortic aneurysm (I71.0), abdominal aortic aneurysm (I71.4), and aortic dissection (I71.1). Each subtype has specific diagnostic criteria based on imaging findings and clinical presentation.
I71 should be used when there is a confirmed diagnosis of an aortic aneurysm or dissection. It is essential to differentiate it from other cardiovascular conditions, such as I70 (atherosclerosis), which does not involve aneurysmal changes. Accurate coding is critical for appropriate treatment and reimbursement.
Documentation for I71 should include detailed clinical notes describing symptoms, risk factors, and imaging results that confirm the diagnosis of an aortic aneurysm or dissection. Surgical reports, if applicable, and follow-up notes are also important to support the diagnosis and treatment plan.
