In simple words: This code indicates mild stage dementia due to a known medical condition, along with the presence of anxiety.

Major neurocognitive disorder in other diseases classified elsewhere, mild, with anxiety.This code is used to describe mild dementia caused by a medical condition other than those specifically listed in other dementia categories (e.g., Alzheimer's disease, vascular dementia) and accompanied by anxiety.

Example 1: A patient with a history of hypothyroidism presents with mild cognitive impairment and symptoms of anxiety. After ruling out other causes, the physician diagnoses dementia due to hypothyroidism and uses F02.A4., A patient with a traumatic brain injury experiences mild memory loss and difficulty concentrating, along with increased anxiety. The physician determines the cognitive decline and anxiety are a direct result of the injury, thus F02.A4 is applicable., A patient with a long-standing vitamin B12 deficiency develops mild cognitive impairment and reports feeling anxious and restless. F02.A4 is used to document the dementia and anxiety secondary to the deficiency.

Documentation should clearly link the dementia and anxiety to the underlying physiological condition. This may include imaging studies, laboratory results, neuropsychological testing, and detailed clinical evaluation notes. The severity of dementia should support a "mild" classification, and the anxiety should be documented as a clinically significant feature.

** It is important to distinguish F02.A4 from other dementia codes to ensure accurate reporting and reimbursement. The documentation should support the diagnosis of mild dementia and anxiety related to the underlying condition.Consider HCCs and RXHCCs for risk adjustment purposes.
