Atherosclerosis Of The Thoracic Aorta: Exploring The ICD-10 Code And Treatment Options

What is Atherosclerosis of the Thoracic Aorta ICD 10?

Atherosclerosis of the thoracic aorta is a condition characterized by the buildup of plaque in the walls of the aorta, the main artery that carries oxygen-rich blood from the heart to the rest of the body. This plaque is made up of cholesterol, fat, calcium, and other substances that can harden and narrow the artery, restricting blood flow and increasing the risk of heart attack, stroke, and other cardiovascular problems.

Code Information

ICD--CM Diagnosis Code I
ICD–CM Diagnosis Code I

The ICD-10 code for atherosclerosis of the thoracic aorta is I70.1. This code is used to classify and report this condition in medical records and billing systems, allowing healthcare providers and insurance companies to track and monitor the prevalence and treatment of the disease.

Diagnostic Related Groups (MS-DRG)

In terms of MS-DRG, atherosclerosis of the thoracic aorta falls under DRG 299 – Peripheral Vascular Disorders with MCC (Major Complications or Comorbidities). This grouping helps healthcare providers estimate the resources needed to treat patients with this condition and determine appropriate reimbursement rates.

Convert to ICD-9 Code

For those still using ICD-9 codes, the equivalent code for atherosclerosis of the thoracic aorta is 440.0. It’s important to ensure accurate coding and documentation when transitioning between code sets to avoid errors and discrepancies in patient records.

Code History

The ICD-10 code I70.1 was introduced in 2016 as part of the regular updates and revisions to the International Classification of Diseases coding system. This change aimed to improve the specificity and accuracy of reporting atherosclerosis of the thoracic aorta and other cardiovascular conditions.

Approximate Synonyms

Other terms that may be used interchangeably with atherosclerosis of the thoracic aorta include aortic atherosclerosis, aortic arteriosclerosis, and aortic atheroma. These synonyms reflect the different aspects and manifestations of the disease in medical literature and practice.

Clinical Information

Atherosclerosis of the thoracic aorta typically develops slowly over time, often without noticeable symptoms until complications arise. The condition can lead to the formation of blood clots, aneurysms, or ruptures in the aorta, which can be life-threatening and require immediate medical attention.


The exact cause of atherosclerosis of the thoracic aorta is not fully understood, but several factors are known to contribute to its development. These include high cholesterol, high blood pressure, smoking, diabetes, obesity, and a sedentary lifestyle. Genetics and family history also play a role in predisposing individuals to the disease.


Many people with atherosclerosis of the thoracic aorta may not experience any symptoms until the condition becomes severe or leads to complications. When symptoms do occur, they may include chest pain, shortness of breath, fatigue, dizziness, and palpitations. In some cases, aortic dissection or aneurysm may present with sudden, severe pain in the chest or back.


Diagnosing atherosclerosis of the thoracic aorta typically involves a combination of medical history review, physical examination, imaging tests (such as CT angiography or MRI), and laboratory tests (such as lipid profile or blood glucose level). These diagnostic tools help healthcare providers assess the extent of plaque buildup and determine the best course of treatment.


The treatment of atherosclerosis of the thoracic aorta aims to reduce the risk of complications, improve blood flow, and manage symptoms. This may involve lifestyle changes (such as quitting smoking, eating a healthy diet, and exercising regularly), medications (such as statins, blood pressure-lowering drugs, or blood thinners), and in some cases, surgical procedures (such as angioplasty, stent placement, or bypass surgery).


Atherosclerosis of the thoracic aorta is a serious condition that requires timely diagnosis and appropriate management to prevent complications and improve outcomes. By understanding the causes, symptoms, diagnosis, and treatment options for this disease, healthcare providers can help patients reduce their risk of heart disease and lead healthier lives.
