- Billable — Valid for Submission

- Not Chronic
F06.2 is a billable ICD-10-CM diagnosis code for psychotic disorder with delusions due to known physiological condition. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026) and groups to MS-DRG 884. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 442 closely related codes. Coders also document this condition as organic delusional disorder. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Schizophrenia spectrum and other psychotic disorders.

Psychotic Disorders
Psychotic disorders are severe mental disorders that cause abnormal thinking and perceptions. People with psychoses lose touch with reality. Two of the main symptoms are delusions and hallucinations. Delusions are false beliefs, such as thinking that someone is plotting against you or that the TV is sending you secret messages.
