In simple words: This code describes a type of dementia caused by a physical illness, where the person experiences symptoms like hallucinations, paranoia, or delusions.

Major neurocognitive disorder in other diseases classified elsewhere, unspecified severity, with psychotic disturbance such as hallucinations, paranoia, suspiciousness, or delusional state.

Example 1: A patient with a history of Huntington's disease develops dementia and experiences hallucinations., A patient with multiple sclerosis exhibits signs of dementia and paranoia., A patient with a traumatic brain injury develops dementia and exhibits delusional behavior.

Documentation should include evidence of dementia, presence of psychotic disturbance, and the underlying physiological condition causing the dementia. Details about the patient's cognitive decline, behavioral changes, and impact on daily living are essential. Supporting documentation might include neuropsychological testing, imaging studies, and clinical evaluations.

** The code specifically describes dementia accompanied by psychotic symptoms. It is crucial to differentiate this from other dementia-related codes that might describe behavioral disturbances, mood disturbances, or anxiety without psychotic features.
