F02.81
Dementia in other diseases classified elsewhere, unspecified severity, with behavioral disturbance
Non-billable headerNot valid on its own. Use one of the more specific codes under it.
F02.81 is a non-billable ICD-10-CM code header for dementia in other diseases classified elsewhere, unspecified severity, with behavioral disturbance. Report a more specific code from it instead. It is part of the FY2027 code set, effective October 1, 2026. The more specific codes under it are F02.811 Dementia in other diseases classified elsewhere, unspecified severity, with agitation and F02.818 Dementia in other diseases classified elsewhere, unspecified severity, with other behavioral disturbance. Its coding notes include a Code first instruction, 1 Excludes1 entry and 3 Excludes2 entries.
Guidelines tip
From the FY2027 Official Guidelines. ICD10Ref adds no rules of its own.
Dementia codes depend on severity documented by the provider. If severity is not documented, the unspecified severity code is assigned. If severity progresses during an inpatient stay, one code is assigned for the highest level.
Code first
If the underlying condition listed here is present and known, sequence it first.

Notes
Also from chapter/block level (1 note)
Inherited from F01–F09 Mental disorders due to known physiological conditions
- This block comprises a range of mental disorders grouped together on the basis of their having in common a demonstrable etiology in cerebral disease, brain injury, or other insult leading to cerebral dysfunction. The dysfunction may be primary, as in diseases, injuries, and insults that affect the brain directly and selectively; or secondary, as in systemic diseases and disorders that attack the brain only as one of the multiple organs or systems of the body that are involved.
