Impact Of ICD-10 Codes On Aortic Stenosis Diagnosis And Treatment

What is ICD-10 Code for Aortic Stenosis?

ICD-10 code I35.0 is used to classify aortic stenosis, a condition where the aortic valve in the heart narrows and restricts blood flow. This can lead to symptoms such as chest pain, shortness of breath, and fatigue. Aortic stenosis can be caused by age-related wear and tear on the valve, congenital heart defects, or other underlying medical conditions.

The ICD-10 code for aortic stenosis is a specific alphanumeric code used by healthcare providers to classify and document medical diagnoses. This code helps healthcare professionals track and analyze data related to aortic stenosis, including prevalence, treatment outcomes, and healthcare costs.

For aortic stenosis, the corresponding MS-DRG is 302, which is titled Cardiac Valve & Other Major Cardiothoracic Procedures with Cardiac Catheterization. This DRG is used to group patients with aortic stenosis who undergo specific cardiac procedures for reimbursement and analysis purposes.

Convert to ICD-9 Code

In the previous version of the coding system, ICD-9, aortic stenosis was classified under code 395.0. Healthcare providers may need to convert this code to the new ICD-10 code I35.0 when documenting and billing for aortic stenosis cases.

Code History

The ICD-10 code for aortic stenosis, I35.0, was introduced as part of the International Classification of Diseases, Tenth Revision in 1994. This code has been updated and revised over the years to reflect changes in medical knowledge and terminology related to aortic stenosis.

Approximate Synonyms

Other terms and synonyms that may be used to describe aortic stenosis include calcific aortic stenosis, degenerative aortic stenosis, and valvular aortic stenosis. These terms are used interchangeably in medical literature and documentation.

Clinical Information

Aortic stenosis is a common heart valve disorder that can lead to serious complications if left untreated. The condition is often asymptomatic in the early stages, but as the valve narrows further, patients may experience symptoms such as chest pain, dizziness, and fainting. Aortic stenosis can be diagnosed through physical exams, imaging tests, and cardiac catheterization.


Aortic stenosis can be caused by a variety of factors, including age-related degeneration of the valve, congenital heart defects, rheumatic fever, and calcification of the valve leaflets. Risk factors for developing aortic stenosis include high blood pressure, high cholesterol, and a family history of heart valve disorders.


The symptoms of aortic stenosis can vary depending on the severity of the condition. Common symptoms include chest pain, shortness of breath, fatigue, dizziness, and fainting. In severe cases, aortic stenosis can lead to heart failure, stroke, and sudden cardiac death.


Diagnosing aortic stenosis typically involves a combination of physical exams, imaging tests such as echocardiography, and cardiac catheterization. Healthcare providers may also perform blood tests to assess heart function and rule out other potential causes of symptoms.


Treatment for aortic stenosis depends on the severity of the condition and the presence of symptoms. Mild cases may be managed with medications to control blood pressure and cholesterol, while severe cases may require surgical intervention such as valve replacement or repair. In some cases, transcatheter aortic valve replacement (TAVR) may be an option for high-risk patients.


In conclusion, aortic stenosis is a serious heart valve disorder that can lead to significant morbidity and mortality if left untreated. Proper diagnosis and management of aortic stenosis are essential to prevent complications and improve patient outcomes. Healthcare providers should be familiar with the ICD-10 code I35.0 for aortic stenosis to accurately document and bill for this condition.
