Acute paranoid reaction

This code represents a transient psychotic disorder characterized by acute onset of paranoid delusions, often accompanied by hallucinations, anxiety, and disorganized thought processes. It is typically a short-lived condition, often triggered by severe stress or trauma, and resolves within a few days to weeks.

Use this code when documenting an acute, temporary psychotic episode primarily featuring paranoid ideation. Documentation should clearly indicate the sudden onset of paranoid delusions, often in response to a precipitating stressor, and the absence of a chronic psychotic disorder or substance-induced psychosis.

• Differentiate from chronic paranoid disorders (e.g., paranoid schizophrenia) which would use codes from the 295 series.
• Ensure documentation specifies "acute" and "paranoid reaction" to support this specific diagnosis.
• Exclude cases where paranoia is clearly secondary to a general medical condition or substance use, which would require different primary diagnoses.
