Delusional Disorder is rated by the U.S. Department of Veterans Affairs under DC 9208 of 38 CFR § 4.130, DC 9208 across 6 severity tiers (0% / 10% / 30% / 50% / 70%…). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303.
Delusional Disorder is a psychotic condition defined by one or more fixed, false beliefs (delusions) persisting at least one month, where apart from the delusion and its direct ramifications, functioning is not markedly impaired and behavior is not obviously bizarre. Common subtypes are persecutory, jealous, grandiose, erotomanic, and somatic, and unlike schizophrenia the criteria are not met for prominent hallucinations, disorganized speech, or negative symptoms. Insight is characteristically poor, so the person experiences the belief as real rather than as a symptom, which often delays diagnosis and treatment.
