Acute diastolic (congestive) heart failure
ICD-10 I50.31 is a billable code used to indicate a diagnosis of acute diastolic (congestive) heart failure.
Acute diastolic heart failure, also known as acute congestive heart failure, is characterized by the heart's inability to fill adequately during diastole, leading to increased pressures in the heart and pulmonary circulation. Clinically, patients may present with symptoms such as shortness of breath, fatigue, and fluid retention, often exacerbated by physical activity or stress. The anatomy involved includes the left ventricle, which fails to relax properly, resulting in elevated left atrial pressures and pulmonary congestion. Disease progression can be rapid, often precipitated by factors such as hypertension, ischemic heart disease, or arrhythmias. Diagnostic considerations include a thorough clinical assessment, echocardiography to evaluate diastolic function, and biomarkers such as B-type natriuretic peptide (BNP) levels. Management typically involves diuretics, antihypertensive medications, and lifestyle modifications to alleviate symptoms and improve quality of life.

I50.31 covers acute diastolic heart failure, which may arise from conditions such as hypertension, myocardial ischemia, or valvular heart disease. It is characterized by impaired ventricular filling and elevated pressures, leading to pulmonary congestion and systemic symptoms.
I50.31 should be used when a patient presents with acute symptoms of heart failure specifically related to diastolic dysfunction. It is important to differentiate it from chronic heart failure codes (e.g., I50.32) and other types of heart failure to ensure appropriate treatment and reimbursement.
Documentation supporting I50.31 should include clinical notes detailing the patient's symptoms, diagnostic tests confirming diastolic dysfunction (such as echocardiography), and any relevant lab results, particularly BNP levels. Clear documentation of the acute nature of the condition is essential.
