2020 ICD-10-CM Diagnosis Code F02.81

Dementia in other diseases classified elsewhere with behavioral disturbance

    2016 2017 2018 2019 2020 Billable/Specific Code Manifestation Code
  • F02.81 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
  • Short description: Dementia in oth diseases classd elswhr w behavioral disturb
  • The 2020 edition of ICD-10-CM F02.81 became effective on October 1, 2019.
  • This is the American ICD-10-CM version of F02.81 - other international versions of ICD-10 F02.81 may differ.
ICD-10-CM Coding Rules
  • F02.81 describes the manifestation of an underlying disease, not the disease itself.
Applicable To
  • Dementia in other diseases classified elsewhere with aggressive behavior
  • Dementia in other diseases classified elsewhere with combative behavior
  • Dementia in other diseases classified elsewhere with violent behavior
  • Major neurocognitive disorder in other diseases classified elsewhere with aggressive behavior
  • Major neurocognitive disorder in other diseases classified elsewhere with combative behavior
  • Major neurocognitive disorder in other diseases classified elsewhere with violent behavior

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

    Mental disorders due to known physiological conditions

    Note
    • 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.
