Dem in other dis classd elswhr, mild, with psych disturb

This code describes a mild stage of dementia that is a manifestation of another underlying medical condition, such as Parkinson's disease or Huntington's disease. The patient exhibits cognitive decline impacting daily activities, along with symptoms like hallucinations or delusions.

Apply this code when documentation clearly indicates mild cognitive impairment secondary to a specified neurological or systemic disease, and the patient is experiencing psychotic features. Ensure the physician explicitly links the dementia to the underlying condition and specifies the severity and presence of psychotic symptoms.

• Always sequence the underlying disease causing the dementia first, followed by this code.
• Distinguish from F02.B2 (moderate) and F02.C2 (severe) based on the documented severity of cognitive impairment.
• Ensure documentation specifies "with psychotic disturbance" to differentiate from codes without this feature.
