Hantavirus (cardio)-pulmonary syndrome [HPS] [HCPS]

📋Clinical Description

This code represents a severe, often fatal, respiratory illness caused by hantaviruses. It is characterized by rapid onset of respiratory distress, pulmonary edema, and cardiogenic shock, without significant renal involvement. The condition progresses quickly and requires intensive medical care.

🎯When to Use

Use this code when documentation explicitly states a diagnosis of Hantavirus Pulmonary Syndrome (HPS) or Hantavirus Cardiopulmonary Syndrome (HCPS). This diagnosis is typically confirmed by serological testing or PCR for hantavirus. The patient will present with acute respiratory failure and evidence of cardiac involvement.

💡Coding Tips

Do not use this code if the documentation indicates renal manifestations; instead, refer to A98.5.
Ensure the documentation clearly differentiates HPS from other forms of hantavirus disease.
Code any associated acute respiratory failure or cardiac complications separately, following sequencing guidelines.
