An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

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.
