297.9
ICD-9-CMThis code signifies a mental health condition characterized by prominent paranoid ideation, delusions of persecution, or suspiciousness, where the specific type of paranoid disorder cannot be further classified. It indicates a psychotic disturbance primarily involving paranoia without other defining features of a more specific paranoid psychosis.
This code is appropriate when a patient presents with significant paranoid symptoms, but the diagnostic workup is incomplete, or the clinician has not yet established a more definitive diagnosis such as paranoid schizophrenia or delusional disorder. It should be used when documentation clearly states "paranoid state, unspecified" or similar terminology indicating a provisional or undifferentiated paranoid condition.
