2025 ICD-10-CM code F02.A
Dementia in other diseases classified elsewhere, mild.
Medical necessity for this code requires demonstrating a causal link between the underlying physiological condition and the mild dementia. The documentation should clearly establish that the cognitive impairment is a direct consequence of the underlying condition.
Diagnosis and management of the underlying condition causing dementia is crucial. Comprehensive assessment should include cognitive testing, neuroimaging, and laboratory tests to determine the etiology. Collaboration with specialists, such as neurologists or geriatricians, might be necessary.

- Mental disorders due to known physiological conditions (F01-F09)
In simple words: This code is used when someone has mild memory loss and other thinking problems because of a known medical problem like an illness or injury.
Major neurocognitive disorder due to another medical condition, mild.This code should be used when a patient has mild dementia as a result of a medical condition not classified elsewhere. Code first the underlying physiological condition, such as Alzheimer's disease (G30.-), Parkinson's disease (G20.-), or traumatic brain injury (S06.-).Excludes1: mild neurocognitive disorder due to known physiological condition with or without behavioral disturbance (F06.7-) Excludes2: dementia in alcohol and psychoactive substance disorders (F10-F19 with .17, .27, .97) and vascular dementia (F01.5-, F01.A-, F01.B-, F01.C-).
Example 1: A patient with a history of Parkinson's disease presents with mild memory impairment and difficulty with executive functions., A patient experiences mild cognitive decline following a traumatic brain injury., A patient with a history of hypothyroidism develops mild dementia, which improves with thyroid hormone replacement.
Documentation should include evidence of dementia such as cognitive assessments, a description of the symptoms, their impact on daily life, and the underlying medical condition causing the dementia. The documentation should clearly link the cognitive decline to the underlying condition.
