Hemoptysis

BILLABLE STATUSYes

Code Description

ICD-10 R04.2 is a billable code used to indicate a diagnosis of hemoptysis.

Key Diagnostic Point:

Hemoptysis refers to the expectoration of blood or blood-stained sputum from the respiratory tract, specifically from the lungs or bronchi. It can range from small streaks of blood to large volumes of blood, and its presence often indicates an underlying pathology. Common causes include infections such as pneumonia or tuberculosis, malignancies, pulmonary embolism, and chronic bronchitis. The clinical context is critical, as hemoptysis can be a sign of serious conditions requiring immediate evaluation. Diagnostic approaches typically involve a thorough history and physical examination, imaging studies like chest X-rays or CT scans, and possibly bronchoscopy to visualize the airways. Laboratory tests may include complete blood counts, coagulation profiles, and sputum cultures to identify infectious agents. The severity and frequency of hemoptysis can guide the urgency of intervention and further diagnostic workup.

Code Complexity Analysis

Medium Complexity

Complexity Factors

  • Variety of potential underlying causes
  • Need for detailed clinical documentation
  • Differentiation from other types of bleeding
  • Potential for serious conditions requiring immediate attention

Audit Risk Factors

  • Inadequate documentation of the cause of hemoptysis
  • Failure to specify the volume of blood expectorated
  • Misclassification of hemoptysis as a symptom of another condition
  • Lack of follow-up documentation for ongoing cases

Frequently Asked Questions

What is the difference between hemoptysis and hematemesis?

Hemoptysis is the expectoration of blood from the respiratory tract, while hematemesis refers to vomiting blood from the gastrointestinal tract. Accurate documentation is essential to differentiate between the two.
