In simple words: This refers to a situation where someone has dementia caused by a physical condition, and they’re experiencing behavioral changes, like sleep problems or inappropriate social behavior.It's important to also identify the specific physical problem causing the dementia.

This code signifies dementia with unspecified severity due to a known physiological condition, accompanied by behavioral disturbances other than agitation, psychotic disturbance, mood disturbance, or anxiety.The underlying physiological condition must be coded separately.

Example 1: A patient with Parkinson's disease (G20) experiences increasing memory loss and displays socially inappropriate behavior., A patient with a traumatic brain injury (S06.-) develops dementia and starts experiencing sleep disturbances and disinhibition., A patient with Huntington's disease (G10) shows signs of dementia and also has difficulty controlling their impulses.

Documentation should clearly specify the underlying physiological condition causing the dementia and detail the specific behavioral disturbances exhibited. The severity of the dementia (mild, moderate, or severe) should be documented if known.
