In simple words: This refers to a moderate stage of memory loss and cognitive decline caused by a diagnosed physical illness, along with changes in behavior.

This code signifies moderate dementia caused by a disease classified elsewhere, accompanied by behavioral disturbances.The underlying physiological condition causing the dementia should be coded first.

Example 1: A patient with moderate Parkinson's disease (G20) is exhibiting memory problems, confusion, and aggressive behavior. The dementia is attributed to Parkinson's, and F02.B1 is used as a secondary code after G20., A patient with Huntington's disease (G10) demonstrates moderate cognitive decline, including difficulty with daily tasks, and experiences hallucinations. F02.B1 is applied after G10 to specify the dementia with behavioral disturbance (hallucinations)., A patient with a history of traumatic brain injury (S06.-) now presents with moderate dementia, including disorientation and significant personality changes (e.g., irritability and social withdrawal). S06.- is coded first, followed by F02.B1.

Documentation should clearly describe the severity of dementia (moderate), the type of behavioral disturbance, and the underlying physiological condition responsible for the dementia.Diagnostic tests and clinical findings supporting the diagnosis should also be included.

** This code provides a general categorization. It is crucial to use more specific codes if available for accurate representation and reporting. Always consult the latest ICD-10-CM guidelines for proper code selection and documentation requirements.
