Code Description

ICD-10 F02.83 is a billable code used to indicate a diagnosis of dementia in other diseases classified elsewhere, unspecified severity, with mood disturbance.

Key Diagnostic Point:

F02.83 refers to dementia that occurs as a result of other diseases not specifically classified under dementia categories, characterized by unspecified severity and accompanied by mood disturbances such as depression or anxiety. This code is often used when dementia symptoms arise from conditions like Parkinson's disease, Huntington's disease, or multiple sclerosis. Patients may exhibit cognitive decline, memory loss, and impaired reasoning, alongside mood disturbances that can complicate their overall clinical picture. The presence of mood disturbances can exacerbate cognitive symptoms, leading to increased caregiver burden and necessitating a comprehensive approach to management that includes both cognitive and emotional support. Accurate coding requires careful documentation of the underlying disease, the severity of dementia, and the nature of mood disturbances to ensure appropriate treatment and reimbursement.

Code Complexity Analysis

Medium Complexity

Complexity Factors

  • Variety of underlying diseases that can cause dementia
  • Need for precise documentation of mood disturbances
  • Differentiation from other types of dementia codes
  • Potential overlap with other mental health diagnoses

Audit Risk Factors

  • Inadequate documentation of the underlying disease
  • Failure to specify the nature of mood disturbances
  • Misclassification of dementia severity
  • Inconsistent use of related codes

Frequently Asked Questions

What is the significance of mood disturbance in F02.83?

Mood disturbances can significantly impact the management and treatment of dementia, affecting both cognitive function and the quality of life for patients and caregivers. Accurate documentation of these symptoms is crucial for appropriate coding and care planning.
