Nonrheumatic pulmonary valve disorder, unspecified
ICD-10 I37.9 is a billable code used to indicate a diagnosis of nonrheumatic pulmonary valve disorder, unspecified.
Nonrheumatic pulmonary valve disorder, unspecified, refers to a range of conditions affecting the pulmonary valve that are not caused by rheumatic fever. The pulmonary valve is located between the right ventricle and the pulmonary artery, regulating blood flow from the heart to the lungs. Clinical presentation may include symptoms such as dyspnea, fatigue, and cyanosis, which can arise from obstructive or regurgitant lesions. Disease progression can vary, with some patients remaining asymptomatic for years while others may develop significant heart failure or arrhythmias. Diagnostic considerations include echocardiography, which is the primary imaging modality for assessing valve structure and function, as well as cardiac MRI or CT for detailed anatomical evaluation. The absence of specific etiology in I37.9 necessitates thorough clinical assessment to rule out other underlying conditions, including congenital heart defects or degenerative valve disease.

I37.9 encompasses various nonrheumatic pulmonary valve disorders, including but not limited to pulmonary valve stenosis, insufficiency, and other unspecified abnormalities of the pulmonary valve that are not attributable to rheumatic disease.
I37.9 should be used when the specific type of nonrheumatic pulmonary valve disorder is not clearly defined or documented. If a more specific diagnosis is available, such as I37.0 or I37.1, those codes should be utilized.
Documentation should include a detailed clinical history, physical examination findings, results from echocardiography or other imaging studies, and any relevant laboratory tests that support the diagnosis of a nonrheumatic pulmonary valve disorder.
