The ICD-10-CM is a catalog of diagnosis codes used by medical professionals for medical coding and reporting in health care settings. The Centers for Medicare and Medicaid Services (CMS) maintain the catalog in the U.S. releasing yearly updates.

Why ICD-10 codes are important
The procedure code 02RX0KZ is in the medical and surgical section and is part of the heart and great vessels body system, classified under the replacement operation. The applicable bodypart is thoracic aorta, ascending/arch. 02RX0KZ replaces the following previously assigned ICD-10-PCS code (s):
You may have been surprised when your doctor said you have mild aortic stenosis (AS), a defect that can narrow the aortic valve opening and restrict blood flow out of the heart to the aorta. However, in people with mild AS, symptoms are usually minor and may be dismissed as normal signs of aging.
Signs and symptoms generally occur when narrowing of the valve is severe. Some people with aortic valve stenosis may not have symptoms for many years. Signs and symptoms of aortic valve stenosis may include: Abnormal heart sound (heart murmur) heard through a stethoscope.
Aortic stenosis is a type of heart valve disease. Your doctor may classify it as mild, moderate, or severe.
What is aortic valve stenosis? Aortic stenosis is one of the most common and serious valve disease problems. Aortic stenosis is a narrowing of the aortic valve opening. Aortic stenosis restricts the blood flow from the left ventricle to the aorta and may also affect the pressure in the left atrium.
Aortic stenosis is most commonly caused by calcium buildup on the aortic valve over time. These calcium deposits that often come with age make the valve tissue stiff, narrow, and unyielding.
The classic physical finding of aortic stenosis is a harsh, late-peaking systolic murmur that is loudest over the second right intercostal space and radiates to the carotid arteries.
Without treatment, a person's life expectancy with aortic stenosis after symptoms develop is 1–3 years. Around 50–68% of symptomatic people die within 2 years. Often, they die suddenly. However, aortic valve replacement surgery significantly increases life expectancy.
Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure to replace a narrowed aortic valve that fails to open properly (aortic valve stenosis). In this procedure, surgeons insert a catheter into the leg or chest and guide it to the heart.
However, there are no medications that can reverse aortic stenosis. The only cure is replacing the diseased valve. Usually, heart valve replacement requires open-heart surgery.
Aortic insufficiency, a form of valvular heart disease, occurs when the aortic valve of the heart leaks and causes blood to flow in the wrong direction. As a result, the heart cannot pump efficiently, causing symptoms like fatigue and shortness of breath.
Aortic valve stenosis causes a thickening and narrowing of the valve between the heart's main pumping chamber (left ventricle) and the body's main artery (aorta). The narrowing creates a smaller opening for blood to pass through. Blood flow from the heart to the rest of the body is reduced or blocked.
Of the 55,567 patients, 1,902 had a single coronary artery with angiographically moderate stenosis (defined as a narrowing of 50%-69%) and results of at least one postoperative angiogram available.
So, when coding aortic valve disease, you will need to know if the disease is stenosis or insufficiency or both , also whether other valves are also involved, and if the disease is rheumatic, nonrheumatic or congenital. A simple statement of “valve disease” will not allow you to code to the greatest specificity possible.
Aortic valve insufficiency is when the valve leaflets don’t meet to form a seal after allowing the contents of the heart chamber to be expelled. This lack of proper closure allows blood to leak back into the left ventricle, thus regurgitation. Symptoms of aortic insufficiency are basically the same as aortic stenosis. Additionally, the left ventricle can also be damaged, resulting in heart failure.
I08.0 Rheumatic disorders of both mitral and aortic valves
There are two main types of valve disease: stenosis and insufficiency . Stenosis of a heart valve is a narrowing of the valve opening, impeding the expulsion of the heart chamber contents. Stenosis of the aortic valve can negatively impact the patient resulting in fatigue, shortness of breath and poor exercise tolerance. Additionally, aortic stenosis can negatively impact the structure of the left ventricle causing it to lose efficiency which can lead to heart failure. Think of pushing against a closed door; eventually you will fatigue.
There are four valves in the heart that separate either the heart chambers from each other, or separate blood flow from heart blood flow. They are, in the left heart, the mitral and aortic valves and in the right heart, the tricuspid and pulmonary valves.
Coding for aortic valve disease requires the documentation of the type of disease. The disease is assumed to be nonrheumatic unless otherwise stated, but with a caveat. If there is unspecified aortic valve disease with mitral and/or tricuspid valve involvement, the disease is assumed to be rheumatic. Per ICD-10 Excludes 1 note, we are guided to code in the I08.x.
