G30-G31Primary Range
Diseases of the nervous system, specifically Alzheimer's disease and other degenerative diseases of the nervous system
This range includes codes for Alzheimer's disease and other neurodegenerative conditions, which are relevant for coding mixed dementia when Alzheimer's is a component.
Mental and behavioral disorders due to known physiological conditions, specifically dementia
This range includes codes for dementia in Alzheimer's disease and other specified dementias, which are used in conjunction with G30-G31 codes for mixed dementia.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G30.8 | Other Alzheimer's disease | Use when mixed dementia includes Alzheimer's disease and is explicitly documented as 'mixed'. |
|
| F00.2* | Dementia in Alzheimer's disease, mixed type | Use when mixed dementia is documented with Alzheimer's as a component. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Use when mixed dementia is documented with Alzheimer's as a component.
Applicable To
- Dementia in Alzheimer's disease with other specified types
Excludes
- Dementia in other diseases classified elsewhere (F02.-)
Clinical Validation Requirements
- Documentation of mixed dementia with Alzheimer's
- Neuroimaging or lab results confirming multiple etiologies

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Mixed Dementia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G30.8.
Impact
Clinical: May lead to inappropriate treatment plans., Regulatory: Non-compliance with ICD-10 coding standards., Financial: Potential loss of reimbursement due to unspecified coding.
Mitigation Strategy
Educate providers on the importance of specifying 'mixed dementia'., Use EHR prompts to ensure complete documentation.
Impact
Reimbursement: May result in lower reimbursement due to unspecified coding., Compliance: Non-compliance with coding guidelines for specificity., Data Quality: Decreases data accuracy and quality.
Mitigation Strategy
Query for specific etiologies and use appropriate codes.
Impact
Risk of audits due to unspecified dementia coding.
Mitigation Strategy
Ensure explicit documentation of mixed dementia and use appropriate codes.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
