Acute right heart failure

This code signifies the sudden onset or worsening of the heart's inability to effectively pump blood from the right ventricle into the pulmonary circulation, leading to systemic venous congestion. It is characterized by symptoms such as peripheral edema, ascites, and jugular venous distension.

Assign this code when documentation explicitly states "acute right heart failure" or describes a new or acutely exacerbated episode of right ventricular dysfunction. Supporting documentation should include clinical findings consistent with acute right-sided heart failure, such as elevated central venous pressure or signs of fluid overload.

• Differentiate from chronic right heart failure (I50.812) or unspecified right heart failure (I50.810).
• Always code any underlying cause of the right heart failure, such as pulmonary hypertension or valvular disease, as an additional diagnosis.
• Ensure documentation specifies "acute" to justify the use of this specific code.
