Find information on moderate aortic stenosis diagnosis, including clinical documentation, medical coding (ICD-10-CM I35.1, I35.2), echocardiogram interpretation, and treatment options. Learn about aortic valve area calculation, peak aortic jet velocity, mean pressure gradient, and symptoms associated with moderate AS. This resource provides guidance for healthcare professionals on accurate diagnosis and appropriate management of moderate aortic stenosis patients.
Also known as
Aortic valve stenosis
Moderate aortic valve stenosis, including calcified or rheumatic.
Nonrheumatic aortic valve disorders
Covers other nonrheumatic aortic valve disorders, which may be related.
Rheumatic heart diseases
Includes rheumatic aortic valve diseases if stenosis is rheumatic in origin.
Heart failure
May be used if heart failure is a consequence of the aortic stenosis.

Coding aortic stenosis without specifying rheumatic vs. non-rheumatic origin impacts severity and reimbursement.
Lack of documented peak velocity, mean gradient, or valve area hinders accurate stenosis severity coding (mild, moderate, severe).
Insufficient documentation of symptoms associated with moderate aortic stenosis impacts clinical validation and coding accuracy.
Patient presents with symptoms suggestive of moderate aortic stenosis, including exertional dyspnea, chest pain, and presyncope. Physical examination reveals a harsh systolic murmur heard best at the right second intercostal space radiating to the carotids. The patient's ECG shows left ventricular hypertrophy. Echocardiography confirms moderate aortic stenosis with an aortic valve area between 1.0 and 1.5 cm2, a mean pressure gradient across the aortic valve between 20 and 40 mmHg, and an aortic valve peak velocity between 3.0 and 4.0 m/s. Aortic valve calcification is noted. The patient's medical history includes hypertension and hyperlipidemia, both medically managed. Assessment: Moderate aortic stenosis. Plan: Continue current medications for hypertension and hyperlipidemia. Recommend regular cardiology follow-up with repeat echocardiography in 6-12 months to monitor aortic valve disease progression. Patient education provided regarding symptoms of worsening aortic stenosis, including heart failure and angina, and the importance of seeking prompt medical attention if these develop. Shared decision-making regarding future aortic valve replacement will be initiated at the next cardiology appointment based on symptom progression and echocardiographic findings. Differential diagnosis includes other causes of valvular heart disease, such as mitral stenosis and aortic regurgitation, which have been ruled out based on the echocardiogram. ICD-10 code I35.1, moderate aortic valve stenosis, is assigned.
