Dementia in other diseases classd elswhr, mild, with anxiety

This code describes a mild form of dementia that is a manifestation of another underlying medical condition, not a primary neurodegenerative disease. Patients exhibit cognitive decline affecting daily activities, accompanied by clinically significant anxiety symptoms. The "mild" specifier indicates that the cognitive deficits are noticeable but do not significantly impair independence in instrumental activities of daily living.

Use this code when documentation clearly links a patient's mild dementia to an underlying medical condition (e.g., Parkinson's disease, Huntington's disease, HIV, multiple sclerosis) and specifies the presence of anxiety. The medical record must explicitly state "mild dementia" and "with anxiety" in the context of the primary disease.

• Always sequence the underlying disease causing the dementia first, followed by this code.
• Ensure documentation specifies "mild" dementia; otherwise, a different severity code (e.g., F02.B4, F02.C4) would be appropriate.
• Distinguish from primary neurodegenerative dementias (e.g., Alzheimer's) which are coded under F00.xx or F03.xx.
