F02.81Dementia in other diseases classified elsewhere, unspecified severity, with behavioral disturbance

F02.81 is the ICD-10-CM diagnosis code for dementia in other diseases classified elsewhere, unspecified severity, with behavioral disturbance. It belongs to category F02 (dementia in other diseases classified elsewhere), block F01-F09 (mental disorders due to known physiological conditions) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within F02.8 (dementia in other diseases classified elsewhere, unspecified severity), F02.81 is specifically for dementia in other diseases classified elsewhere, unspecified severity, with behavioral disturbance. Related codes cover without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety (F02.80), with psychotic disturbance (F02.82), with mood disturbance (F02.83) and with anxiety (F02.84).

To report this condition, pick the subcode that matches the documentation: F02.811 (agitation) and F02.818 (disturbance).

Code first the underlying physiological condition, such as: Alzheimer's (G30.-), cerebral lipidosis (E75.4), Creutzfeldt-Jakob disease (A81.0-), epilepsy and recurrent seizures (G40.-) and 20 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2023 (title revised).

Before ICD-10, this condition was coded in ICD-9-CM as 294.11 (dementia in conditions classified elsewhere with behavioral disturbance).
