Inclusion Terms
These terms are the conditions for which that code is to be used. 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.
- Paranoid reaction
- Psychogenic paranoid psychosis
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.

About the F23 Code Range
ICD-10 code F23 is used to classify brief psychotic disorder, a condition characterized by sudden, short-term episodes of psychosis that typically last less than one month. This code is essential for accurately identifying and documenting these acute, transient mental health episodes.
The code F23 covers various presentations commonly known as schizophrenic reaction, reactive psychoses, acute paranoid reaction, and bouffée délirante. These synonyms reflect how brief psychotic disorder may appear with sudden changes in perception, confusion, paranoia, or mood, often triggered by stress or trauma. Healthcare professionals rely on this code to distinguish brief psychotic episodes from longer-lasting psychotic disorders within the schizophrenia spectrum. For medical coders, recognizing the many terms—such as acute polymorphic psychotic disorder with or without schizophrenic symptoms—is crucial for accurate coding and treatment planning. Using the ICD-10 code for brief psychotic disorder ensures clear communication about these transient but significant mental health conditions.
