Acute and subacute endocarditis
ICD-10 I33 is a used to indicate a diagnosis of acute and subacute endocarditis.
Acute and subacute endocarditis refers to the inflammation of the inner lining of the heart chambers and valves, typically caused by bacterial infection. Clinically, patients may present with 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 endocardial surface. Disease progression can vary; acute endocarditis develops rapidly, often leading to severe complications such as heart failure or systemic emboli, while subacute endocarditis progresses more slowly, allowing for more subtle symptoms and potentially less severe outcomes. Diagnostic considerations include blood cultures, echocardiography, and clinical criteria such as the Duke criteria, which help differentiate between acute and subacute forms. Early diagnosis and treatment are critical to prevent serious complications, including valvular damage and septicemia.

I33 covers both acute and subacute endocarditis, which can be caused by various pathogens, including bacteria, fungi, and other microorganisms. It is essential to identify the causative organism for appropriate treatment.
I33 should be used when the patient is diagnosed with acute or subacute endocarditis, characterized by specific clinical findings and diagnostic criteria. It is important to differentiate it from other heart conditions such as I38, which is more general.
Documentation should include clinical findings such as fever, heart murmurs, and embolic phenomena, along with laboratory results from blood cultures and echocardiography findings that confirm the diagnosis of endocarditis.
