Pulmonary Vascular Disease:

What Is Pulmonary Vascular Disease?

Pulmonary vascular disease is the clinical term for disease influencing the blood vessels prompting or from the lungs. Most types of pulmonary vascular disease cause windedness. The meaning of pulmonary vascular disease is straightforward: any condition that influences the blood vessels along the course between the heart and lungs.

 This interaction constantly tops off the blood with oxygen, and leaves carbon dioxide alone breathed out. Here's the way the cycle works:

  • Oxygen-poor blood gets back from the body's tissues through the veins back to the correct side of the heart.
  • The correct heart siphons oxygen-poor blood through the pulmonary corridors into the lungs. This blood gets loaded up with oxygen.
  • The oxygen-rich blood gets back from the lungs back to one side of the heart. The left heart siphons the oxygen-rich blood into the body through the aorta and numerous different courses.
  • Any piece of the heart-lung blood circuit can get harmed or blocked, prompting pulmonary vascular disease.


The side effects of pulmonary vascular disease differ as per a few components:

  • The suddenness of the interaction influencing the pulmonary blood vessels
  • Which pulmonary blood vessels are influenced?
  • The amount of the pulmonary vascular system is influenced

For instance, an abrupt, huge pulmonary embolism impeding an enormous pulmonary conduit can cause extreme windedness and chest torment. Yet, an exceptionally little pulmonary embolism (hindering just a little blood vessel) may cause no recognizable manifestations.

In spite of the fact that manifestations of pulmonary vascular disease can fluctuate broadly, every one of the reasons for pulmonary vascular disease has a bunch of common side effects. These pulmonary diseases include:

  • Pulmonary blood vessel hypertension
  • Pulmonary embolism
  • Pulmonary venous hypertension

Description Percentage

Primary pulmonary hypertension, or; chronic pulmonary thrombo-embolism with evidence of pulmonary hypertension, right ventricular hypertrophy, or cor pulmonale, or; pulmonary hypertension secondary to other obstructive disease of pulmonary arteries or veins with evidence of right ventricular hypertrophy or cor pulmonale

Description Percentage

Chronic pulmonary thromboembolism requiring anticoagulant therapy, or; following inferior vena cava surgery without evidence of pulmonary hypertension or right ventricular dysfunction

Description Percentage

Symptomatic, following resolution of acute pulmonary embolism

Description Percentage

Asymptomatic, following resolution of pulmonary thromboembolism


Note: Evaluate other residuals following pulmonary embolism under the most appropriate diagnostic code, such as chronic bronchitis (DC 6600) or chronic pleural effusion or fibrosis (DC 6844), but do not combine that evaluation with any of the above evaluations.
