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.

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.
