2025 ICD-10-CM code Q23.2
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Congenital malformations - Congenital malformations of the circulatory system Congenital malformations, deformations and chromosomal abnormalities (Q00-Q99) Feed
Congenital mitral stenosis; a narrowing of the mitral valve present at birth.
Medical necessity for procedures related to congenital mitral stenosis is established based on the severity of the stenosis, the presence of symptoms (dyspnea, fatigue, cyanosis, etc.), and the impact on the patient's quality of life.Justification often involves documenting the severity of the stenosis using echocardiographic measurements (e.g., mitral valve area, pressure gradient), as well as clinical signs and symptoms of heart failure or other complications.
Cardiologists, pediatric cardiologists, and cardiac surgeons are typically involved in the diagnosis and management of congenital mitral stenosis.The clinical responsibility includes thorough evaluation of the patient's condition, comprehensive review of cardiac imaging studies (such as echocardiograms), assessment of symptom severity, and collaborative decision-making regarding treatment options ranging from medical management to surgical intervention.

In simple words: This code describes a heart problem a baby is born with. The mitral valve, which is a part of the heart, doesn't open properly, causing a narrowing that makes it harder for blood to flow through the heart. This can lead to tiredness, breathing difficulties, or chest discomfort.
Q23.2, Congenital mitral stenosis, is an ICD-10-CM code that classifies the congenital narrowing of the mitral valve, a heart valve located between the left atrium and the left ventricle. This condition is present at birth and can lead to various cardiovascular complications.The severity varies greatly, impacting blood flow and potentially causing symptoms such as shortness of breath, fatigue, and chest pain. Diagnosis usually involves echocardiography and cardiac catheterization.Treatment may range from medical management to surgical intervention, depending on the severity of stenosis and the patient's clinical presentation.This code is specifically for congenital mitral stenosis and should not be used for acquired mitral stenosis.
Example 1: A newborn infant presents with cyanosis and respiratory distress.Echocardiography reveals significant congenital mitral stenosis. The infant undergoes cardiac catheterization which confirms the diagnosis and the severity of the stenosis.Surgical intervention (mitral valvotomy or valve replacement) is planned., A 5-year-old child experiences recurrent episodes of shortness of breath and fatigue.A transthoracic echocardiogram is performed, demonstrating moderate congenital mitral stenosis. The child is initially managed medically with diuretics and other supportive care.Regular follow-up echocardiograms are scheduled to monitor disease progression., A 10-year-old presents with symptoms consistent with congestive heart failure.Advanced imaging reveals severe congenital mitral stenosis with significant left atrial enlargement.The child undergoes surgical mitral valve repair with excellent outcomes.
Complete medical history, including prenatal history, physical examination findings, echocardiographic reports (transthoracic and/or transesophageal), cardiac catheterization reports (if performed), laboratory results (including complete blood count, electrolytes, and cardiac biomarkers), and details of the treatment plan and response.
** This code should only be used for congenital mitral stenosis. Acquired mitral stenosis should be coded appropriately using other ICD-10-CM codes.Always refer to the latest ICD-10-CM guidelines for accurate coding practices.
