Often asymptomatic, but can cause murmurs, shortness of breath, chest pain, or dizziness.
Diagnosed by echocardiogram, often during routine checkups or investigations for heart murmurs.

Complete code families applicable to Q23.1
When to use each related code
| Description | When to use |
|---|---|
| Two aortic valve leaflets instead of three. | Use for congenital bicuspid aortic valve. Consider complications like stenosis or regurgitation. |
| Narrowing of the aortic valve opening. | Aortic valve stenosis, often due to BAV or rheumatic fever. Code severity (mild, moderate, severe). |
| Aortic valve leaflets don't close, causing backflow. | Aortic regurgitation/insufficiency. Specify cause (e.g., BAV, endocarditis) and severity. |
Best-practice checklist
- ✓Document aortic valve morphology (bicuspid)
- ✓Specify congenital vs. acquired BAV
- ✓Note aortic valve function (stenosis/regurgitation)
- ✓Include echocardiogram findings
- ✓Record associated cardiac conditions
Common pitfalls to avoid
Coding BAV requires specifying congenital (Q23.1) vs. acquired (I35.0). Miscoding impacts data accuracy and reimbursement.
Aortic stenosis or regurgitation often co-occurs with BAV. Incomplete coding of these impacts severity and risk adjustment.
Documentation lacking fusion type (e.g., right-left, right-noncoronary) may hinder accurate coding and quality reporting.
Best-practice tips
- 01Document valve morphology, aortopathy, and aortic dimensions for accurate ICD-10 coding (Q23.1).
- 02Regular echocardiography with BAV severity grading improves CDI and patient outcomes.
- 03Timely cardiology referral and surgical intervention planning based on BAV progression prevents complications.
- 04Thorough family history documentation aids genetic counseling and cascade screening for BAV (ICD-10 Z83.89).
- 05Monitor for associated coarctation, using appropriate CPT codes for echocardiography and other diagnostics.
Step-by-step checklist

Assess for aortic stenosis, regurgitation, and dilation. Document severity.
- 4
Review family history for BAV, aortopathy, or sudden cardiac death.
Ready-to-paste narrative
Patient presents with findings suggestive of bicuspid aortic valve (BAV), also known as congenital bicuspid aortic valve. Assessment includes auscultation for aortic stenosis murmur, aortic regurgitation murmur, and click. Evaluation for symptoms such as chest pain, shortness of breath (dyspnea), syncope, and palpitations was conducted. Differential diagnosis includes other causes of valvular heart disease such as rheumatic heart disease, infective endocarditis, and degenerative aortic valve disease. Diagnostic workup may include echocardiogram (transthoracic echocardiography, TTE, or transesophageal echocardiography, TEE), electrocardiogram (ECG or EKG), and cardiac MRI to assess aortic valve morphology, function, and degree of stenosis or regurgitation. Patient’s medical history, family history of bicuspid aortic valve, and risk factors for aortic complications such as hypertension, hyperlipidemia, and smoking were reviewed. Treatment plan may include medical management with antihypertensives, statins, and prophylactic antibiotics for endocarditis prevention, or surgical intervention such as aortic valve repair or aortic valve replacement (AVR) depending on the severity of the valve dysfunction and patient’s symptoms. Patient education regarding the importance of regular follow-up, echocardiographic surveillance, and potential complications including aortic aneurysm or dissection was provided. ICD-10 code Q23.1 (Bicuspid aortic valve) and relevant CPT codes for diagnostic and therapeutic procedures will be documented. This documentation supports medical necessity for services rendered and facilitates accurate medical billing and coding.
Common questions and answers
What are the most effective diagnostic imaging modalities for differentiating bicuspid aortic valve from a tricuspid aortic valve in asymptomatic adult patients?+
Differentiating a bicuspid aortic valve (BAV) from a tricuspid aortic valve (TAV) in asymptomatic adults often necessitates high-quality imaging. Echocardiography, specifically transesophageal echocardiography (TEE), is often the initial and most readily available modality, offering detailed visualization of valve morphology and function. However, in challenging cases where echocardiography is inconclusive, cardiac computed tomography (CCT) or cardiac magnetic resonance imaging (CMR) can provide superior spatial resolution, enabling clearer delineation of the valve leaflets, aortic root, and ascending aorta. CCT offers excellent visualization of calcification and provides accurate measurements for surgical planning, while CMR excels in assessing blood flow dynamics and identifying aortopathy, a common association with BAV. Consider implementing a multi-modality imaging approach when echocardiography findings are equivocal. Explore how the addition of CCT or CMR can enhance diagnostic accuracy and inform clinical decision-making in BAV assessments.
How does the management of bicuspid aortic valve with moderate aortic stenosis differ in asymptomatic versus symptomatic patients, and when is surgical intervention warranted?+
The management of bicuspid aortic valve (BAV) with moderate aortic stenosis (AS) hinges on the presence or absence of symptoms and the severity of AS progression. Asymptomatic patients with moderate BAV-associated AS require careful monitoring, including regular echocardiography (typically every 6-12 months) to track AS progression and assess left ventricular function. Exercise testing can be useful for unmasking latent symptoms and risk-stratifying patients. Symptomatic patients, even with moderate AS, warrant a more proactive approach. Surgical aortic valve replacement (SAVR) or transcatheter aortic valve replacement (TAVR) is indicated when symptoms appear, regardless of AS severity. In asymptomatic patients, SAVR/TAVR is considered when AS progresses rapidly, left ventricular dysfunction develops, or the patient becomes high-risk for adverse events. Learn more about the current guidelines for managing BAV-associated AS and explore the latest advancements in surgical and interventional techniques.
What are the key genetic considerations and family screening recommendations for patients diagnosed with bicuspid aortic valve and associated aortopathy?+
Bicuspid aortic valve (BAV) is often hereditary, with a significant genetic component. Genetic testing can sometimes identify specific genes associated with BAV, such as NOTCH1, but genetic testing is not routinely recommended for all patients. However, family screening is crucial. First-degree relatives (parents, siblings, and children) of patients with BAV should undergo echocardiography to assess for the presence of BAV and associated aortopathy. This screening should be performed even if family members are asymptomatic. Early detection can facilitate timely intervention and improve outcomes. Explore how genetic counseling can provide valuable information and support for families affected by BAV. Consider implementing a standardized family screening protocol in your clinical practice for patients diagnosed with BAV.
