Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

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.

Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the J43 range.

Centrilobular Emphysema

Pulmonary emphysema in which the changes are noted around the central pulmonary artery and bronchiole of a secondary pulmonary lobule, particularly in the upper lobes of the lung. It is the most common type of pulmonary emphysema and it is the most closely associated with cigarette smoking.

Emphysema

A pathological accumulation of air in tissues or organs.

Lung, Hyperlucent

A lung with reduced markings on its chest radiograph and increased areas of transradiancy (hyperlucency). A hyperlucent lung is usually associated with pulmonary emphysema or PNEUMOTHORAX.

Panlobular Emphysema

Pulmonary emphysema in which the changes are noted throughout a secondary pulmonary lobule, particularly in the lower lobes of the lung.

Swyer-James Syndrome

A pneumothorax condition marked by complete absence of markings in the chest radiograph.

About the J43 Code Range

Emphysema is an abnormal buildup of air in tissues or organs. This category sits among chronic diseases of the lower respiratory system.

The subdivisions distinguish emphysema of one lung, J43.0, from panlobular emphysema, J43.1, and centrilobular emphysema, J43.2. They also include other emphysema, J43.8, and emphysema without a specified form, J43.9.
