Code Description

ICD-10 F02 is a billable code used to indicate a diagnosis of dementia in other diseases classified elsewhere.

Key Diagnostic Point:

F02 is used to classify dementia that arises as a consequence of other diseases that are classified in different categories. This includes dementia associated with conditions such as Parkinson's disease, Huntington's disease, and multiple sclerosis. Patients with F02 may exhibit a range of cognitive impairments, including memory loss, difficulty with problem-solving, and impaired judgment. Behavioral symptoms such as agitation, depression, and personality changes are also common. The diagnosis of dementia in these cases requires careful assessment of the underlying disease and its impact on cognitive function. Cognitive assessments, including standardized tests, are essential for evaluating the severity of dementia and guiding treatment. Caregiver support is crucial, as caregivers often face significant challenges in managing the behavioral and psychological symptoms associated with dementia, necessitating education and resources to improve care quality.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more precise coding of dementia types, improving the ability to capture the complexity of dementia associated with other diseases. This specificity aids in better patient management and resource allocation.

ICD-9 vs ICD-10

Frequently Asked Questions

What is the difference between F02 and F00?

F02 is used for dementia resulting from other diseases, while F00 specifically refers to dementia due to Alzheimer's disease.

How do I document cognitive assessments for F02?

Document the type of cognitive tests performed, results, and how they relate to the patient's overall condition.
