Code Description

ICD-10 A32.82 is a billable code used to indicate a diagnosis of listerial endocarditis.

Key Diagnostic Point:

Listerial endocarditis is a rare but serious infection of the heart valves caused by the bacterium Listeria monocytogenes. This condition typically occurs in individuals with compromised immune systems, such as the elderly, pregnant women, and those with underlying health issues like diabetes or cancer. The infection can lead to severe complications, including heart failure, septicemia, and embolic events. Patients may present with symptoms such as fever, chills, fatigue, and new or worsening heart murmurs. Diagnosis is often confirmed through blood cultures, which may take time to yield results, complicating timely treatment. Treatment usually involves prolonged courses of antibiotics, such as ampicillin or a combination of ampicillin and gentamicin, due to the organism's resistance patterns. The prognosis can vary significantly based on the patient's overall health and the timeliness of treatment initiation. Early recognition and intervention are crucial to improving outcomes in affected patients.
