ICD-10-CM F22: Delusional Disorders Overview
Delusional disorders represent persistent, non-bizarre or bizarre false beliefs that are not attributable to mood disorders or substance use and primarily affect thought content and perception. These diagnoses target psychiatric conditions affecting cognition, perception, and social functioning. Accurate coding of delusional disorders is important for clinical documentation and appropriate reimbursement because it communicates diagnosis specificity and complexity to payers and care teams.
