Psychotic disorder w hallucin due to known physiol condition

This code describes a mental health condition characterized by the presence of hallucinations (e.g., seeing or hearing things that aren't there) that are directly caused by an underlying medical illness or physiological disturbance. The psychotic symptoms are not better explained by another mental disorder or substance use.

Apply this code when documentation clearly links psychotic symptoms, specifically hallucinations, to a diagnosed medical condition such as a neurological disorder, endocrine imbalance, or systemic infection. The physician's notes should explicitly state the physiological cause and rule out other psychiatric or substance-induced etiologies.

• Ensure the medical record explicitly states the physiological condition causing the hallucinations; this code requires a causal link.
• Do not use this code if the hallucinations are due to alcohol or other psychoactive substances (refer to F10-F19 with appropriate fifth characters).
• Distinguish from schizophrenia (F20.-) where the etiology is not primarily physiological.
