Code Description

ICD-10 F02.818 is a billable code used to indicate a diagnosis of dementia in other diseases classified elsewhere, unspecified severity, with other behavioral disturbance.

Key Diagnostic Point:

F02.818 refers to dementia that arises as a complication of other diseases not specifically classified under dementia categories. This code is used when the severity of dementia is unspecified, but the patient exhibits behavioral disturbances such as aggression, agitation, or mood swings. Common underlying conditions may include Parkinson's disease, Huntington's disease, or multiple sclerosis. The behavioral disturbances associated with this type of dementia can significantly impact the patient's quality of life and complicate caregiving. Cognitive assessments are crucial for determining the extent of cognitive impairment and guiding treatment. Caregivers often face challenges due to the unpredictable nature of behavioral symptoms, necessitating support and education to manage these disturbances effectively.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying conditions that can lead to dementia.
  • Unspecified severity complicates treatment planning.
  • Behavioral disturbances require careful documentation.
  • Need for comprehensive cognitive assessments.

Audit Risk Factors

  • Inadequate documentation of behavioral disturbances.
  • Failure to specify the underlying disease causing dementia.
  • Lack of cognitive assessment results in the medical record.
  • Inconsistent use of the code across different encounters.
