In simple words: This code indicates a mild form of dementia caused by a medical condition not specifically identified elsewhere. The person experiences some memory and thinking problems that affect their ability to perform certain daily tasks. They don't have significant behavioral issues, hallucinations, mood swings, or excessive worry.

This code represents a mild stage of dementia resulting from a disease other than those specifically listed elsewhere in the ICD-10-CM classification.It is characterized by a decline in cognitive abilities, including memory, thinking, and reasoning, that is sufficient to impact daily functioning, particularly instrumental activities of daily living.This diagnosis specifies the absence of behavioral disturbances, psychotic disturbances, mood disturbances, and anxiety commonly associated with dementia.

Example 1: A patient with mild cognitive impairment due to hypothyroidism is diagnosed with F02.A0 after neuropsychological testing and ruling out other causes of dementia., A patient with a history of traumatic brain injury now exhibits mild dementia with functional limitations, fitting the criteria for F02.A0. , A patient with a confirmed diagnosis of systemic lupus erythematosus experiences mild cognitive decline impacting instrumental activities of daily living, and exhibits no behavioral or psychological symptoms.The dementia is coded as F02.A0 after appropriate evaluation.

Documentation should include details of the underlying medical condition causing the dementia, evidence of cognitive decline from history, physical examination, and neuropsychological testing if available. Functional limitations should be assessed and documented.Absence of behavioral, mood, or psychotic disturbances should be explicitly noted.

** It is crucial to distinguish this code from other forms of mild dementia (F01.A- for vascular dementia, F03.A- for unspecified dementia).It's also important to accurately assess and document any behavioral or psychological symptoms to ensure accurate coding.
