2025 ICD-10-CM code I34.8
(Active) Effective Date: N/A Revision Date: N/A Diseases of the circulatory system - Other nonrheumatic mitral valve disorders Diseases of the circulatory system (I00-I99) Feed
This code represents other nonrheumatic disorders affecting the mitral valve, excluding specific conditions like mitral insufficiency, prolapse, or stenosis.
Medical necessity for coding I34.8 is established through a thorough clinical evaluation, supporting diagnostic testing (e.g., echocardiogram, cardiac MRI), and documentation that the patient's condition requires treatment and management of the mitral valve dysfunction.The documentation must clearly demonstrate the nature and severity of the disorder, as well as the patient's symptoms and their relation to the mitral valve pathology.
The clinical responsibility for this code falls upon cardiologists or other healthcare professionals specializing in cardiovascular diseases. They are responsible for diagnosing the specific mitral valve disorder, determining the appropriate treatment, and ensuring accurate documentation for billing purposes.
In simple words: This code describes problems with the mitral valve in the heart that aren't caused by rheumatic fever and aren't specifically mitral insufficiency, prolapse, or stenosis.It covers various other heart valve issues needing medical attention.
ICD-10-CM code I34.8, "Other nonrheumatic mitral valve disorders," encompasses various nonrheumatic conditions of the mitral valve not otherwise specified by codes I34.0, I34.1, or I34.2.These could include, but are not limited to, mitral valve annulus calcification,mitral valve dysfunction due to degenerative changes, or other structural abnormalities not categorized elsewhere. Accurate coding requires precise documentation specifying the nature of the mitral valve abnormality.
Example 1: A 65-year-old patient presents with symptoms of heart failure.Echocardiography reveals significant mitral valve annulus calcification, leading to mitral regurgitation. Code I34.81 is used, which is a more specific code within the I34.8 category., A 70-year-old patient with a history of coronary artery disease undergoes cardiac catheterization, revealing moderate mitral regurgitation attributed to myxomatous degeneration of the mitral valve leaflets.The most appropriate code in this instance is I34.8., A 40-year-old patient experiences chest pain and shortness of breath.Echocardiography demonstrates a structurally abnormal mitral valve with restricted leaflet movement, not fitting the criteria for stenosis or prolapse. This scenario would require further investigation and might utilize I34.89.
Complete echocardiogram report detailing the specific abnormality of the mitral valve.Physician's notes should describe the clinical presentation, diagnostic findings, and the rationale for assigning code I34.8.Any relevant imaging studies (such as cardiac MRI) should also be included in the documentation.
** This code is used when the specific type of nonrheumatic mitral valve disorder is not specified or is otherwise not classifiable using other I34 codes.Always refer to the latest ICD-10-CM coding guidelines for the most up-to-date information.
