What is Pneumonia?
The textbook pneumonia definition is a lung infection brought on by bacteria, viruses, or fungi. The infection causes inflammation in the lungs' alveoli, which are small air sacs. As the alveoli swell with liquid or pus, breathing becomes challenging. Pneumonia caused by bacteria or viruses can then easily spread to others. This implies that they can transmit from person to person when airborne droplets from a cough or sneeze are inhaled. These kinds of pneumonia can also spread by contact with surfaces or objects that have been exposed to pathogens that cause the disease.
The pneumonia ICD-10 code used to specify a diagnosis for financial reimbursement is J18. 9
