Medicare covers some COPD treatments but not others. Read on to learn what COPD is, some of the most common treatments and what Medicare covers.

What is COPD?
Chronic obstructive pulmonary disease, or COPD, is a progressive disease that can cause coughing, chest tightness, mucus, wheezing and shortness of breath, according to the National Heart, Lung, and Blood Institute. It is also known as chronic bronchitis or emphysema.
It is a relatively common disease that impacts about 1 in 9 Medicare beneficiaries.
Cigarette smoke or long-term exposure to lung irritants like chemicals, air pollution and dust may cause COPD.
The disease becomes worse as it progresses and can limit your ability to perform daily activities.
