Acute and subacute infective endocarditis
ICD-10 I33.0 is a billable code used to indicate a diagnosis of acute and subacute infective endocarditis.
Acute and subacute infective endocarditis (IE) is an infection of the inner lining of the heart chambers and valves, primarily caused by bacteria, fungi, or other infectious agents. Clinically, patients may present with symptoms such as fever, chills, fatigue, and heart murmurs, alongside signs of systemic embolization. The anatomy involved includes the heart valves (mitral, aortic, tricuspid, and pulmonary) and the endocardium. Disease progression can vary; acute infective endocarditis develops rapidly, often leading to severe complications within days to weeks, while subacute infective endocarditis progresses more slowly, potentially allowing for a more insidious onset of symptoms. Diagnostic considerations include blood cultures, echocardiography (transthoracic or transesophageal), and laboratory tests to identify the causative organism and assess for complications such as heart failure or abscess formation. Early diagnosis and treatment are crucial to prevent severe morbidity and mortality associated with this condition.

I33.0 specifically covers acute and subacute infective endocarditis, which may be caused by various pathogens including Streptococcus, Staphylococcus, and enterococci. It is characterized by the rapid onset of symptoms in acute cases and a more gradual presentation in subacute cases.
I33.0 should be used when the patient is diagnosed with acute or subacute infective endocarditis, as opposed to other forms of endocarditis or heart infections. Accurate differentiation is essential for appropriate treatment and coding.
Documentation should include clinical findings such as fever, heart murmurs, and embolic phenomena, results from blood cultures, echocardiography findings, and treatment plans. Comprehensive notes detailing the patient's history and clinical course are also essential.
