Chronic right heart failure

This code signifies a long-standing impairment of the right ventricle's ability to pump blood effectively, leading to systemic venous congestion. It is characterized by symptoms such as peripheral edema, ascites, and hepatomegaly, resulting from the heart's inability to adequately circulate blood to the lungs.

Assign this code when documentation explicitly states "chronic right heart failure" or "chronic cor pulmonale" with evidence of right ventricular dysfunction. It is appropriate for patients with persistent symptoms and signs of right-sided heart failure that have developed over an extended period.

• Distinguish from acute right heart failure (I50.811) or unspecified right heart failure (I50.810) based on documentation of chronicity.
• Code any underlying causes of right heart failure, such as chronic obstructive pulmonary disease (COPD) or pulmonary hypertension, as additional diagnoses.
• Ensure the laterality of the heart failure (right) is clearly documented to support this specific code.
