Type 2 Excludes

Type 2 Excludes Help

A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (F45) and the excluded code together.

A category of psychiatric disorders which are characterized by the presence of physical symptoms that suggest a medical condition but are not fully explained by any known medical reasons.

The symptoms must cause clinically significant distress or impairment in social, occupational, or other areas of functioning. In contrast to factitious disorders and malingering, the physical symptoms are not under voluntary control. (apa, dsm-iv)
