In simple words: This code indicates severe memory loss and cognitive decline with anxiety, caused by a physical condition affecting the brain.This is not due to typical aging, but rather a specific medical problem.

Major neurocognitive disorder in other diseases classified elsewhere, severe, with anxiety. This code represents severe dementia with anxiety resulting from a known physiological condition other than those specifically excluded (e.g., vascular dementia, dementia in alcohol or substance use disorders).The underlying physiological condition should be coded first.

Example 1: A patient with a history of traumatic brain injury now exhibits severe memory loss, confusion, and significant anxiety., A patient with Huntington's disease develops severe dementia and experiences heightened anxiety., A patient with severe dementia due to Parkinson's disease also presents with marked anxiety symptoms.

Documentation should include details of the underlying physiological condition, the severity of the cognitive impairment as determined by standardized cognitive assessments, and the presence and nature of the anxiety symptoms.A clear distinction between dementia-related anxiety and primary anxiety disorders is essential.
