Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

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.

The gastrointestinal device subdivision separates gastric lap bands from other devices. Urinary devices have a separate subdivision. Among other specified devices, insulin pumps and non-vascular catheters have distinct codes. Z46.9 covers an unspecified device.
