| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G30.0 | Alzheimer's disease with early onset | Use when Alzheimer's disease is diagnosed with onset before age 65. |
|
| G30.1 | Alzheimer's disease with late onset | Use when Alzheimer's disease is diagnosed with onset after age 65. |

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

Decision Criteria
clinical Criteria
- Onset before age 65 with genetic confirmation
Applicable To
- Early onset Alzheimer's disease
Excludes
- Vascular dementia (F01.-)
Clinical Validation Requirements
- Onset before age 65
- Genetic testing confirming mutations
Code-Specific Risks
- Misclassification if age of onset is not documented
Coding Notes
- Ensure documentation specifies early onset and any genetic findings.
G30.1 - Alzheimer's disease with late onset
Use when Alzheimer's disease is diagnosed with onset after age 65.
Applicable To
- Late onset Alzheimer's disease
Excludes
- Dementia with Lewy bodies (G31.83)
Clinical Validation Requirements
- Onset after age 65
- Clinical diagnosis based on cognitive decline
Coding Notes
Ensure documentation includes age of onset and cognitive assessment results.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Alzheimer's 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: May lead to inappropriate treatment plans., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.
Mitigation Strategy
Always include patient's age at onset in documentation.
Impact
Reimbursement: May result in lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of patient records.
Mitigation Strategy
Always specify the type of dementia and link it to Alzheimer's when applicable.
Impact
High risk of audit if dementia type is not specified.
Mitigation Strategy
Always document specific dementia type and link to Alzheimer's when applicable.
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.
