Dem in other dis classd elswhr, sev, with other beh distrb

This code signifies severe dementia that is a manifestation of another underlying medical condition, not primarily a neurodegenerative disorder like Alzheimer's. The patient exhibits significant cognitive decline impacting daily living, accompanied by behavioral disturbances beyond simple agitation, such as psychotic features, aggression, or wandering.

Apply this code when documentation clearly links severe dementia and complex behavioral issues to a specific, separately classified disease (e.g., Parkinson's disease, Huntington's disease, HIV disease). The medical record must specify both the severity of the dementia and the nature of the "other behavioral disturbance."

• Ensure the underlying disease causing the dementia is coded first, followed by this code.
• Distinguish "other behavioral disturbance" from "with behavioral disturbance, unspecified" (F02.C11) or "with psychotic disturbance" (F02.C14).
• Verify documentation explicitly states "severe" dementia; otherwise, consider codes for mild or moderate severity.
