ICD-10 F02.8 Dementia in Other Diseases
ICD-10-CM code F02.8 represents 'Dementia in other diseases classified elsewhere' of unspecified severity. As a secondary diagnosis, it's essential to identify the primary condition causing dementia. Clinicians must document patient history, mental status exams, potential cognitive deficits, and any related affective symptoms. This code requires specific attention to the etiological link to the underlying condition. Comprehensive notes on behavioral and psychological symptoms, progression, and healthcare impacts enhance medical records, supporting CMS compliance and audit readiness.
Overview
F02.8 refers to dementia that arises as a complication of other diseases not specifically classified under dementia-related codes. This includes conditions such as Parkinson's disease, Huntington's disease, and other neurodegenerative disorders that can lead to cognitive decline. Patients may exhibit a range of cognitive impairments, including memory loss, difficulty with language, impaired judgment, and changes in personality. Behavioral symptoms such as agitation, depression, and anxiety are also common. The severity of dementia can vary widely among individuals, and it is often challenging to assess due to the underlying disease processes. Caregiver support is crucial, as caregivers often face significant emotional and physical burdens while managing the complexities of dementia care. Effective communication and education about the disease can help caregivers provide better support and improve the quality of life for both themselves and the patient.
Coding Complexity
Rating: Medium
Factors:
- Variety of underlying diseases that can cause dementia
- Overlap of symptoms with other mental health conditions
- Need for comprehensive documentation of cognitive assessments
- Variability in severity and progression of dementia
- Potential for misdiagnosis or underdiagnosis
Comparison:
Compared to codes for specific types of dementia (e.g., Alzheimer's disease), F02.8 is more complex due to the need to identify and document the underlying disease causing the dementia. Specific dementia codes often have clearer diagnostic criteria and established treatment protocols, making them easier to code accurately.
Audit Risk Factors:
- Inadequate documentation of the underlying disease
- Failure to specify the severity of dementia
- Lack of cognitive assessment results
- Inconsistent use of related codes
- Misalignment between diagnosis and treatment provided
Specialty Focus
- Specialty: Neurology
Documentation Requirements: Detailed neurological assessments, cognitive testing results, and documentation of the underlying disease process.
Common Clinical Scenarios: Patients with Parkinson's disease presenting with cognitive decline, or patients with Huntington's disease showing behavioral changes.
Special Considerations: Neurologists must ensure that the documentation clearly links the dementia symptoms to the underlying neurological condition. - Specialty: Geriatrics
Documentation Requirements: Comprehensive geriatric assessments, including cognitive and functional evaluations.
Common Clinical Scenarios: Older adults with multiple comorbidities presenting with cognitive impairment.
Special Considerations: Geriatricians should focus on the impact of dementia on daily living activities and the need for caregiver support.
Coding Guidelines
According to ICD-10 coding guidelines, F02.8 should be used when dementia is documented as a complication of another disease. Coders must ensure that the primary diagnosis reflects the underlying condition, and F02.8 is used as a secondary code to indicate the presence of dementia.
Related CPT Codes
- Code: 96116
Procedure Name: Neuropsychological testing
Clinical Scenario: Used to assess cognitive function in patients with suspected dementia.
Documentation Requirements: Results of cognitive assessments must be documented.
Specialty Considerations: Neurologists and psychologists should collaborate on documentation.
Billing Information
Billing for F02.8 requires comprehensive documentation of the patient's cognitive status, the underlying disease, and any assessments performed. Clear linkage between the diagnosis and treatment provided is essential for reimbursement.

Q: What documentation is required for coding F02.8?
For F02.8, documentation should clearly establish the link between the dementia and the underlying disease classified elsewhere. Medical records must include a detailed patient history, cognitive evaluation findings, mental status assessments, and the severity level of the dementia even if not specified within F02.8. Note the presence of specific behavioral or psychological symptoms, progression rates, and functional impairments. The underlying medical condition should be coded first with dementia F02.8 as a secondary diagnosis. Accurate and thorough documentation ensures compliance with CMS guidelines and supports appropriate reimbursement.
Q: How does F02.8 differ from other dementia codes?
F02.8 is unique as it specifies dementia linked to diseases classified elsewhere, unlike codes for primary dementia types like Alzheimer's (e.g., F00) or specific vascular dementia (e.g., F01). The primary condition underlying F02.8 must be documented first, acknowledging the secondary nature of the dementia. This emphasizes the etiological basis, ensuring that clinicians document the primary disease's ICD-10-CM code alongside F02.8, capturing the full clinical picture.
Q: Why is severity unspecified in F02.8, and how to indicate it?
Though F02.8 does not specify severity, effective documentation should describe the dementia's impact on daily functioning and cognitive abilities. Notes should detail behavior changes, affective symptoms, and decision-making capabilities. Severity can indirectly be indicated by the extent of care required, such as the need for supervision or assistance, enabling more precise clinical evaluation and facilitating better-adjusted care strategies.
Q: What are the coding complexities involving F02.8?
F02.8 poses unique coding challenges due to its nature as a secondary diagnosis contingent on a primary etiological factor. Coders must discern and appropriately apply the primary condition's ICD-10 code first, followed by F02.8. Accurate reflection of the clinical scenario in documentation helps avoid misinterpretation, ensuring audit readiness and avoiding reimbursement issues. Coders should pay particular attention to documentation notes regarding the transmitted conditions and mental or behavioral factors.
Q: What specialty-specific documentation is crucial for F02.8?
Specialty-specific documentation must uphold a cohesive narrative between disciplines like neurology, geriatrics, and psychology. Detailed cognitive assessments, neurologists' evaluations, and psychological reports contribute to a robust record. Cross-referencing notes from specialists aids in substantiating the dementia's link to the primary disease. Thorough documentation ensures a comprehensive understanding, facilitates interspecialty collaboration, and adheres to CMS current auditing standards.
