Congenital malformation of aortic and mitral valves, unsp

This code signifies a birth defect affecting both the aortic and mitral heart valves, where the specific nature of the malformation is not documented. It indicates an abnormality in the structure or function of these critical valves present at birth, without further detail regarding the type of defect (e.g., stenosis, insufficiency, atresia).

Use this code when medical record documentation confirms a congenital malformation involving both the aortic and mitral valves, but the physician has not specified the exact type of malformation. This code is appropriate when the clinical picture points to a combined defect of these valves, but further diagnostic clarity is lacking or not yet determined.

• Avoid using this code if a more specific congenital malformation of either the aortic or mitral valve (e.g., Q23.0, Q23.2) is documented.
• Query the provider for greater specificity regarding the type of malformation if possible, to allow for more precise coding.
• This code should be used when the documentation explicitly states "unspecified" or provides insufficient detail to assign a more specific code for combined aortic and mitral valve malformations.
