Infective myocarditis
ICD-10 I40.0 is a billable code used to indicate a diagnosis of infective myocarditis.
Infective myocarditis is an inflammatory condition of the myocardium, primarily caused by viral infections, though bacterial, fungal, and parasitic infections can also contribute. Clinically, patients may present with symptoms such as chest pain, dyspnea, palpitations, and signs of heart failure. The anatomy involved includes the myocardium, which is the muscular layer of the heart responsible for contraction and pumping blood. Disease progression can vary; some patients may recover fully, while others may develop chronic heart failure or dilated cardiomyopathy. Diagnostic considerations include a thorough clinical history, physical examination, electrocardiogram (ECG), echocardiography, and possibly cardiac MRI or endomyocardial biopsy to confirm the diagnosis and rule out other conditions. Early recognition and treatment are crucial to prevent severe complications and improve outcomes.

I40.0 specifically covers myocarditis caused by infectious agents, primarily viral infections such as Coxsackievirus, adenovirus, and others. It is characterized by inflammation of the myocardium and may present with varying degrees of heart dysfunction.
I40.0 should be used when the myocarditis is confirmed to be of infectious origin. If the myocarditis is due to non-infective causes, such as autoimmune disorders or exposure to toxins, other codes like I40.1 should be used.
Documentation should include clinical findings, laboratory results indicating infection, imaging studies showing myocardial inflammation, and any relevant history of recent infections. A clear rationale for the diagnosis and treatment plan is essential.
