| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G30.0 | Alzheimer's disease with early onset | Use when Alzheimer's disease is diagnosed with symptom onset before age 65. |
|
| F02.81 | Dementia in other diseases classified elsewhere with behavioral disturbance | Use when dementia is accompanied by 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.

Excludes
- Dementia without behavioral disturbance (F02.80)
Clinical Validation Requirements
- Documented behavioral disturbances such as aggression or agitation
Coding Notes
Ensure documentation specifies the type of behavioral disturbance.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Early Onset Dementia 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 treatment planning due to incomplete clinical picture., Regulatory: Potential non-compliance with coding standards., Financial: Loss of potential reimbursement for higher complexity care.
Mitigation Strategy
Ensure detailed documentation of any behavioral symptoms., Use structured templates to capture all necessary information.
Impact
Reimbursement: May result in lower reimbursement due to incomplete coding., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate representation of patient condition in medical records.
Mitigation Strategy
Always pair G30.0 with an appropriate F02.8- code to specify dementia manifestations.
Impact
Risk of audits due to missing secondary codes for dementia manifestations.
Mitigation Strategy
Implement regular training sessions on ICD-10 coding rules for dementia.
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.
