| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G30.0 | Alzheimer's disease with early onset | Use when Alzheimer's disease is diagnosed in patients under 65 years old. |
|
| G30.1 | Alzheimer's disease with late onset | Use when Alzheimer's disease is diagnosed in patients 65 years or older. |
|
| F02.80 | Dementia in other diseases classified elsewhere without behavioral disturbance | Use when dementia is present without behavioral disturbances. |
|
| F02.81 | Dementia in other diseases classified elsewhere with behavioral disturbance | Use when dementia is present with behavioral disturbances. |

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

F02.80Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Dementia in Alzheimer's Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G30.0.
Impact
Clinical: Inaccurate clinical picture affecting treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims or reduced reimbursement.
Mitigation Strategy
Include specific examples of behavioral disturbances in documentation.
Impact
Reimbursement: Incorrect coding can lead to denied claims or reduced reimbursement., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate data affecting clinical decision-making and reporting.
Mitigation Strategy
Always pair G30.x + F02.8x when Alzheimer's etiology is established.
Impact
Inadequate documentation of behavioral symptoms can lead to audit findings.
Mitigation Strategy
Ensure all behavioral symptoms are clearly documented with specific examples.
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.
