Psychotic disorder w delusions due to known physiol cond

This code signifies a mental health condition characterized by the presence of delusions that are directly attributable to a specific, identifiable medical or neurological illness. The psychotic symptoms are not better explained by another mental disorder and are a direct physiological consequence of the underlying condition.

Apply this code when documentation clearly establishes a causal link between a known physiological condition (e.g., brain tumor, endocrine disorder, autoimmune disease, stroke) and the development of delusional symptoms. The medical record should explicitly state that the delusions are "due to" or "secondary to" the physiological condition.

• Always code the underlying physiological condition first, followed by this code.
• Ensure documentation differentiates this from substance-induced psychosis or primary psychotic disorders like schizophrenia.
• Look for phrases like "delusions secondary to [medical condition]" or "psychotic disorder due to [physiological cause]."
