297.8
ICD-9-CMThis code represents a group of psychotic disorders characterized by prominent paranoid delusions that do not meet the full diagnostic criteria for paranoid schizophrenia or delusional disorder. Patients typically experience fixed, false beliefs of persecution, conspiracy, or grandeur, without significant disorganization of thought, prominent hallucinations, or severe functional impairment often seen in other psychotic conditions.
Use this code when documentation specifies a paranoid state that is clearly defined but does not fit into more specific categories like paranoid schizophrenia, delusional disorder, or acute paranoid reaction. This applies to conditions where the primary feature is paranoia, but the clinical picture is atypical or subthreshold for other diagnoses. Supporting documentation should clearly describe the nature of the paranoid ideation and rule out other specified psychotic disorders.
