Delusional disorders
Chapter 5:Mental, Behavioral and Neurodevelopmental disorders
ICD-10 F22 is a billable code used to indicate a diagnosis of delusional disorders.
Delusional disorders are characterized by the presence of one or more delusions that persist for at least one month. These delusions are false beliefs that are firmly held despite evidence to the contrary and can significantly impact an individual's functioning. The delusions can take various forms, including paranoid delusions, grandiose delusions, or somatic delusions. Unlike schizophrenia, individuals with delusional disorders do not exhibit the full range of psychotic symptoms, such as hallucinations or disorganized thinking, which makes the diagnosis more nuanced. The onset of delusional disorders can occur in adulthood, and while the exact cause is often unclear, genetic, environmental, and psychological factors may contribute. Treatment typically involves antipsychotic medications, which can help alleviate symptoms, alongside psychotherapy to support the individual in managing their beliefs and improving their overall functioning. Accurate diagnosis and coding are crucial, as delusional disorders can overlap with other psychotic disorders, necessitating careful clinical assessment.
