2025 ICD-10-CM code I01.1

Acute rheumatic endocarditis is an inflammation of the heart's inner lining (endocardium) specifically affecting the heart valves, a complication of rheumatic fever.

Coding should reflect the specific findings, including the presence or absence of other manifestations of rheumatic heart disease.Appropriate diagnostic confidence indicators may be used in outpatient settings.

Medical necessity is established by the presence of clinical findings consistent with acute rheumatic endocarditis, such as symptoms, physical exam findings and echocardiographic evidence of valve involvement.The severity of the condition determines the need for interventions ranging from medical management to surgical intervention.

Diagnosis and management of acute rheumatic endocarditis usually involve a cardiologist and other specialists.Treatment might include antibiotics (for any associated infection), anti-inflammatory medications (to reduce inflammation), and potentially heart valve surgery depending on severity.

IMPORTANT:Related codes include other manifestations of acute rheumatic fever, such as I01.0 (acute rheumatic pericarditis), I01.2 (acute rheumatic myocarditis), and I01.8 (other acute rheumatic heart disease).

In simple words: Acute rheumatic endocarditis is a heart problem that happens after a strep throat infection if it's not treated properly. It causes inflammation in the heart's inner lining, especially the valves, and can lead to problems with blood flow.This requires prompt medical attention.

Acute rheumatic endocarditis (I01.1) is a serious complication of acute rheumatic fever (ARF), an inflammatory condition that follows a streptococcal infection.It involves inflammation of the endocardium, often resulting in damage to the heart valves (valvulitis).This inflammation leads to the formation of vegetations (small growths) on the valves, potentially causing stenosis (narrowing) or regurgitation (leakage) of blood flow.The condition may manifest with symptoms like fever, heart murmur, fatigue, and shortness of breath, among others.It is crucial to distinguish this condition from infective endocarditis, which is caused by a microbial infection rather than an autoimmune response.

Example 1: A 10-year-old presents with a fever, joint pain (polyarthritis), and a heart murmur following an untreated streptococcal pharyngitis.Echocardiography reveals vegetations on the mitral valve, consistent with acute rheumatic endocarditis.Treatment includes anti-inflammatory medication and close monitoring., A 15-year-old with a history of rheumatic fever experiences worsening shortness of breath and chest pain.Cardiac examination reveals a new systolic murmur, and echocardiography demonstrates significant mitral valve regurgitation secondary to rheumatic endocarditis. Valve repair or replacement surgery is considered., A 12-year-old is diagnosed with acute rheumatic endocarditis after presenting with fever, carditis, and an elevated erythrocyte sedimentation rate.Antibiotics to manage any potential co-existing infection and anti-inflammatory medications to control inflammation are administered. Regular monitoring with echocardiography is crucial.

Detailed history including recent streptococcal infection (with positive throat culture or rapid antigen detection test), physical examination findings (especially cardiac examination), laboratory data (complete blood count, erythrocyte sedimentation rate, C-reactive protein), and echocardiography findings are crucial.

** Accurate diagnosis requires differentiating acute rheumatic endocarditis from infective endocarditis.This distinction is vital for appropriate treatment and prognosis.
