2025 ICD-10-CM code Q23
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Congenital malformations - Congenital malformations of aortic and mitral valves Congenital malformations, deformations and chromosomal abnormalities (Q00-Q99) Feed
Congenital malformations of the aortic and mitral valves.
Modifiers may be applicable depending on the specific procedure or service performed. Consult the most current modifier guidelines for clarification.
Medical necessity for diagnostic and therapeutic interventions (e.g., echocardiography, cardiac catheterization, surgery) is established based on the severity of the congenital valve malformation and its impact on cardiovascular function.Symptomatic patients often require interventions to alleviate symptoms and prevent complications.

In simple words: This code describes birth defects affecting the heart's aortic and mitral valves. These valves control blood flow, and birth defects can cause them to narrow, leak, or both, sometimes leading to serious health problems.
This ICD-10-CM code encompasses congenital (present from birth) structural abnormalities affecting the aortic and/or mitral valves of the heart.These malformations can involve various valve components, including leaflets, cusps, annuli, and chordae tendineae, and may manifest as stenosis (narrowing), regurgitation (leakage), or a combination thereof.The severity can range from asymptomatic to life-threatening, requiring interventions such as surgery or catheterization.
Example 1: A newborn infant is diagnosed with bicuspid aortic valve (BAV) during a routine echocardiogram.The BAV is causing mild aortic stenosis, requiring close monitoring but no immediate intervention., A 10-year-old child presents with symptoms of heart failure (shortness of breath, fatigue) due to severe mitral valve regurgitation diagnosed as congenital. Cardiac catheterization and valve repair are planned., A 25-year-old adult experiences sudden onset chest pain and syncope. Diagnostic imaging reveals critical aortic stenosis secondary to a congenitally malformed bicuspid aortic valve. Urgent valve replacement surgery is indicated.
Complete patient history including family history of congenital heart disease.Echocardiogram report with detailed descriptions of valve morphology, function, and hemodynamic parameters.Cardiac catheterization report (if performed) with pressure measurements and any intervention details.Surgical report (if applicable), including details of the procedure and pathology findings.Relevant clinical notes documenting symptoms, physical examination findings, and response to treatment.
** This code is for use in documenting congenital heart defects and should not be used for acquired valvular disorders.Always refer to the latest ICD-10-CM coding guidelines for accurate coding practices.
