Healthy Lung Month
Share this:

Each year, October is observed as Healthy Lung Month. This month is dedicated to raising awareness about lung disease, the importance of protecting the lungs, and possible ways of avoiding lung health issues. Pulmonology is a branch of internal medicine and pulmonologists are specialized in diagnosing and treating diseases of the respiratory system – the lungs and other organs that help you breathe. Lung diseases may refer to many conditions including lung cancer, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, chronic bronchitis, emphysema, interstitial lung disease, asthma, and infections such as influenza, pneumonia, and tuberculosis. Pulmonary medical coding must be error-free if the medical claims are to be reimbursed by the insurer on time. Assigning the right procedure and diagnosis codes minimizes claim denials and enhances cash in-flow for practices.

To keep the lungs healthy and prevent the risk of lung disease, the American Lung Association recommends exercising regularly, performing breathing exercises, avoiding smoking, avoiding exposure to indoor pollutants that can damage your lungs, reducing exposure to outdoor air pollution and getting vaccines against infectious respiratory. It is also important to screen for lung cancer even if there’s no signs of the condition, as early detection is critical to identifying and beating the disease.

Some of the common symptoms of lung disease include chronic cough that lasts for at least one month, chest pain mainly caused by breathing or coughing, shortness of breath without any physical exertion, chronic mucus production and wheezing. Depending on symptoms and diagnosis, doctors might recommend a lung test or procedure such as bronchoscopy, chest tube procedure, CT scan, lung biopsy, endobronchial ultrasound (EBUS), exhaled nitric oxide test and more. A pulmonologist can treat many kinds of lung problems. Diagnoses should be documented using right ICD-10 codes.
