A79.0

Adenoviral pneumonia

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/05/2025

Code Description

ICD-10 A79.0 is a billable code used to indicate a diagnosis of adenoviral pneumonia.

Key Diagnostic Point:

Adenoviral pneumonia is a respiratory infection caused by adenoviruses, which are a group of viruses that can lead to a variety of illnesses, including respiratory infections, conjunctivitis, and gastroenteritis. This condition is characterized by inflammation of the lung tissue, leading to symptoms such as cough, fever, difficulty breathing, and chest pain. Adenoviral pneumonia is particularly prevalent in children and can occur in outbreaks, especially in crowded settings such as schools and daycare centers. The diagnosis is typically confirmed through clinical evaluation and laboratory tests, including PCR assays or viral cultures. Treatment primarily focuses on supportive care, as there are no specific antiviral therapies for adenoviral infections. Patients with underlying health conditions or weakened immune systems may experience more severe symptoms and complications. Understanding the epidemiology and transmission routes of adenoviruses is crucial, especially in the context of travel-related infections, where exposure to contaminated environments can increase the risk of infection.

Frequently Asked Questions

What are the common symptoms of adenoviral pneumonia?

Common symptoms include cough, fever, difficulty breathing, and chest pain. Symptoms can vary based on the patient's age and health status.

How is adenoviral pneumonia diagnosed?

Diagnosis is typically made through clinical evaluation and confirmed with laboratory tests such as PCR or viral cultures.

What is the treatment for adenoviral pneumonia?

Treatment is primarily supportive, focusing on symptom management, as there are no specific antiviral treatments for adenoviral infections.

Can adenoviral pneumonia lead to complications?

Yes, particularly in individuals with weakened immune systems or underlying respiratory conditions, complications can include severe respiratory distress and secondary infections.
