Thickening and calcification of the aortic valve without significant obstruction of blood flow.
Often asymptomatic. May have a heart murmur. Severe cases can lead to angina or syncope.
Detected incidentally during routine cardiac exams (echocardiogram, EKG).

When to use each related code
| Description | When to use |
|---|---|
| Thickening of aortic valve without obstruction. | Use for aortic valve thickening with normal blood flow. Exclude stenosis. |
| Narrowing of aortic valve, obstructing blood flow. | Use when aortic valve narrowing restricts blood flow. Specify severity if known. |
| Aortic valve calcification without stenosis. | Use when calcium deposits are present on aortic valve without flow obstruction. |
Best-practice checklist
- ✓Document auscultation findings (e.g., ejection systolic murmur)
- ✓Note presence/absence of symptoms (e.g., dyspnea, angina)
- ✓Echocardiogram findings: aortic valve thickening/calcification
- ✓Quantify aortic valve area and peak velocity if available
- ✓Specify if stenosis or regurgitation is present/absent
Common pitfalls to avoid
Coding aortic sclerosis without specifying location (aortic valve) can lead to inaccurate severity reflection and reimbursement.
Confusing sclerosis (I35.0) with stenosis (I35.1/I35.2) leads to incorrect documentation, impacting patient care and billing.
Insufficient documentation of associated symptoms can hinder accurate severity assessment and optimal treatment planning.
Best-practice tips
- 01Document aortic valve morphology and calcification extent for accurate ICD-10 coding (I35.0).
- 02Assess and document aortic jet velocity and mean pressure gradient for proper severity staging.

Ready-to-paste narrative
Patient presents with findings suggestive of aortic valve sclerosis, also known as aortic sclerosis or non-obstructive aortic valve calcification. Physical examination revealed a harsh systolic ejection murmur best heard at the right upper sternal border, radiating to the carotid arteries. No symptoms of angina, syncope, or dyspnea were reported at this time. The patient denies any significant past medical history of cardiac disease. Electrocardiogram showed normal sinus rhythm without evidence of left ventricular hypertrophy. Transthoracic echocardiogram was performed, demonstrating calcification of the aortic valve leaflets without significant stenosis or obstruction to left ventricular outflow. The mean transvalvular gradient and aortic valve area are within normal limits. Assessment includes aortic valve sclerosis (non-rheumatic). Given the absence of hemodynamically significant obstruction, the current plan involves conservative management with regular cardiovascular monitoring, including periodic echocardiograms to assess for disease progression. Patient education provided regarding the natural history of aortic valve sclerosis and potential future need for intervention if stenosis develops. The patient was advised on lifestyle modifications, including heart-healthy diet and exercise, for optimal cardiovascular health. ICD-10 code I35.0, aortic valve sclerosis, was assigned. Follow-up scheduled in six months for repeat clinical evaluation and echocardiography.
Common questions and answers
What are the key differentiating factors in diagnosis between mild aortic valve sclerosis and severe aortic sclerosis requiring intervention?+
Differentiating mild aortic valve sclerosis from severe aortic sclerosis requiring intervention hinges on several key factors. While mild aortic sclerosis often presents asymptomatically with mild leaflet thickening and minimal hemodynamic impact, severe aortic sclerosis is characterized by significant leaflet calcification, restricted valve opening, and noticeable pressure gradients across the aortic valve. Echocardiography plays a crucial role, assessing parameters like peak aortic jet velocity, mean pressure gradient, and aortic valve area. Mild aortic sclerosis typically exhibits a peak velocity < 2.5 m/s, mean gradient < 20 mmHg, and an aortic valve area > 1.5 cm². Severe aortic sclerosis, however, often shows peak velocities > 4.0 m/s, mean gradients > 40 mmHg, and a significantly reduced aortic valve area, often < 1.0 cm². Symptoms like angina, syncope, and heart failure also point towards severe disease requiring intervention, such as aortic valve replacement (AVR). Furthermore, serial echocardiographic monitoring is essential to track disease progression. Consider implementing standardized echocardiography protocols for consistent assessment and explore how risk stratification tools can aid in decision-making for timely intervention.
How does aortic valve sclerosis differ from aortic stenosis in terms of clinical presentation and management for an asymptomatic patient?+
Aortic valve sclerosis and aortic stenosis, while related, differ significantly in clinical presentation and management, particularly in asymptomatic patients. Aortic sclerosis involves leaflet thickening and some calcification without significant obstruction of blood flow. Asymptomatic patients with aortic sclerosis typically exhibit normal blood flow velocities and no significant pressure gradients across the aortic valve. Management focuses on risk factor modification (e.g., controlling hypertension, hyperlipidemia) and routine echocardiographic surveillance to monitor for progression to stenosis. Conversely, aortic stenosis involves significant obstruction of blood flow due to leaflet thickening, calcification, and reduced valve opening. Even in asymptomatic patients, moderate to severe aortic stenosis will demonstrate increased blood flow velocities and pressure gradients across the aortic valve on echocardiography. While management for asymptomatic mild aortic stenosis may also involve watchful waiting and risk factor modification, moderate to severe aortic stenosis necessitates careful monitoring and potential intervention, such as AVR, even in the absence of symptoms, based on risk stratification. Learn more about the latest guidelines for managing asymptomatic aortic stenosis to ensure optimal patient care.
What are the best evidence-based guidelines for monitoring the progression of aortic valve sclerosis and determining the optimal timing for intervention, especially in elderly patients with comorbidities?+
Monitoring the progression of aortic valve sclerosis, especially in elderly patients with comorbidities, requires a careful balance of risk stratification and shared decision-making. Current guidelines recommend regular echocardiographic surveillance, typically every 1-2 years for asymptomatic patients with mild sclerosis, and more frequently (every 6-12 months) for those with moderate sclerosis or rapid progression. The decision for intervention, such as AVR, is complex and should not solely rely on echocardiographic parameters. Factors such as age, frailty, comorbidities, and patient preferences play a crucial role. For elderly patients with comorbidities, a multidisciplinary heart team approach is often recommended. This team, which includes cardiologists, cardiac surgeons, geriatricians, and other specialists, can assess the individual patient's risk profile and weigh the benefits and risks of intervention. Explore how shared decision-making tools can facilitate open communication and ensure that treatment plans align with patient goals. Furthermore, emerging biomarkers and advanced imaging techniques may offer additional insights into disease progression and inform personalized management strategies.
