Mental disorders due to known physiological conditions
ICD-10 codes F01–F09 classify mental disorders that arise from identifiable physiological conditions — including vascular dementia, dementia in Alzheimer's, delirium, and personality changes due to known causes. Accurate coding requires identifying both the mental disorder and its underlying physiological etiology.
