Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Chronic obstructive airway disease NOS
  • Chronic obstructive lung disease NOS

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Information for Patients


COPD

COPD (chronic obstructive pulmonary disease) makes it hard for you to breathe. The two main types are chronic bronchitis and emphysema. The main cause of COPD is long-term exposure to substances that irritate and damage the lungs. This is usually cigarette smoke. Air pollution, chemical fumes, or dust can also cause it.

At first, COPD may cause no symptoms or only mild symptoms. As the disease gets worse, symptoms usually become more severe. They include

  • A cough that produces a lot of mucus
  • Shortness of breath, especially with physical activity
  • Wheezing
  • Chest tightness

Doctors use lung function tests, imaging tests, and blood tests to diagnose COPD. There is no cure. Treatments may relieve symptoms. They include medicines, oxygen therapy, surgery, or a lung transplant. Quitting smoking is the most important step you can take to treat COPD.
