Unspecified Schizophrenia Spectrum and
Other Psychotic Disorder
298.9 (F29)
This category applies to presentations in which symptoms characteristic of a schizophre-
nia spectrum and other psychotic disorder that cause clinically significant distress or im-
pairment in social, occupational, or other important areas of functioning predominate but
do not meet the full criteria for any of the disorders in the schizophrenia spectrum and oth-
er psychotic disorders diagnostic class. The unspecified schizophrenia spectrum and oth-
er psychotic disorder category is used in situations in which the clinician chooses not to
specify the reason that the criteria are not met for a specific schizophrenia spectrum and
other psychotic disorder, and includes presentatio ns in which there is insufficient informa-
tion to make a more specific diagnosis (e.g., in emergency room settings).
