Code Description

ICD-10 F02.84 is a billable code used to indicate a diagnosis of dementia in other diseases classified elsewhere, unspecified severity, with anxiety.

Key Diagnostic Point:

F02.84 refers to dementia that occurs as a result of other diseases classified elsewhere, such as Parkinson's disease, Huntington's disease, or multiple sclerosis. This code is specifically used when the severity of dementia is unspecified and is accompanied by anxiety symptoms. Dementia is characterized by a decline in cognitive function, affecting memory, thinking, and social abilities, which can interfere with daily life. The presence of anxiety can exacerbate cognitive symptoms, leading to increased confusion, agitation, and behavioral changes. Cognitive assessments, such as the Mini-Mental State Examination (MMSE) or Montreal Cognitive Assessment (MoCA), are essential for evaluating the extent of cognitive impairment. Behavioral symptoms may include mood swings, irritability, and withdrawal from social interactions. Caregiver support is crucial, as caregivers often face significant stress and need resources to manage both the patient’s dementia and their own well-being.

Complexity Factors

  • Requires understanding of dementia types and their underlying diseases.
  • Need for accurate documentation of anxiety symptoms.
  • Differentiating between various dementia-related codes.
  • Understanding the impact of co-existing conditions on dementia.

Audit Risk Factors

  • Inadequate documentation of anxiety symptoms.
  • Failure to specify the underlying disease causing dementia.
  • Lack of cognitive assessment results in the medical record.
  • Inconsistent documentation of severity levels.

Specialty Focus

Neurology

Documentation Requirements

Detailed neurological assessments, cognitive testing results, and documentation of anxiety symptoms.

Common Clinical Scenarios

Patients with dementia due to Parkinson's disease presenting with anxiety and cognitive decline.

Billing Considerations

Neurologists must ensure comprehensive documentation of both cognitive and behavioral symptoms to support coding.

Psychiatry

Documentation Requirements

Mental health evaluations, treatment plans addressing anxiety, and documentation of cognitive assessments.

Common Clinical Scenarios

Patients with dementia experiencing significant anxiety impacting their daily functioning.

Billing Considerations

Psychiatrists should document the interplay between dementia and anxiety to justify the use of F02.84.
