Endomyocardial (eosinophilic) disease
ICD-10 I42.3 is a billable code used to indicate a diagnosis of endomyocardial (eosinophilic) disease.
Endomyocardial (eosinophilic) disease is characterized by eosinophilic infiltration of the myocardium, leading to inflammation and potential fibrosis. Clinically, patients may present with symptoms of heart failure, arrhythmias, or chest pain, often accompanied by a history of allergic conditions or drug reactions that could trigger eosinophilia. The anatomy involved primarily includes the myocardium, with possible involvement of the endocardium. Disease progression can lead to significant myocardial damage, resulting in dilated cardiomyopathy and impaired cardiac function. Diagnostic considerations include echocardiography, MRI, and endomyocardial biopsy, which can confirm eosinophilic infiltration. Blood tests to assess eosinophil counts and potential underlying causes of eosinophilia are also critical in the diagnostic process.

I42.3 specifically covers endomyocardial disease characterized by eosinophilic infiltration, which may arise from various etiologies including allergic reactions, drug-induced eosinophilia, or certain infections. It is crucial to differentiate this from other types of cardiomyopathy.
I42.3 should be used when there is clear evidence of eosinophilic infiltration of the myocardium, confirmed through biopsy or imaging, and when symptoms align with eosinophilic myocarditis. It is important to differentiate it from other cardiomyopathies that do not involve eosinophilic processes.
Documentation should include a detailed clinical history, laboratory results showing elevated eosinophil counts, imaging studies, and histopathological findings from endomyocardial biopsy confirming eosinophilic infiltration.
