| 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. |
|
| 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.

Primary ICD-10-CM Codes for dementia with alzheimer's
Decision Criteria
clinical Criteria
- Onset before age 65 with confirmed Alzheimer's diagnosis
Applicable To
- Early-onset Alzheimer's disease
Excludes
- Dementia with Lewy bodies (G31.83)
Clinical Validation Requirements
- Diagnosis confirmed by clinical assessment and neuroimaging
- Onset before age 65
Code-Specific Risks
- Misclassification if onset age is not documented
Coding Notes
- Ensure onset age is clearly documented to differentiate from late-onset.
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
- Frontotemporal dementia (G31.09)
Clinical Validation Requirements
- Diagnosis confirmed by clinical assessment and neuroimaging
- Onset after age 65
Coding Notes
Ensure onset age is clearly documented to differentiate from early-onset.
F02.80 - Dementia in other diseases classified elsewhere without behavioral disturbance
Use when dementia is present without behavioral disturbances.
Applicable To
- Dementia without behavioral disturbance
Excludes
- Dementia with behavioral disturbance (F02.81)
Clinical Validation Requirements
- Cognitive decline documented without behavioral symptoms
Coding Notes
Ensure absence of behavioral symptoms is documented.
F02.81 - Dementia in other diseases classified elsewhere with behavioral disturbance
Use when dementia is present with behavioral disturbances.
Applicable To
- Dementia with behavioral disturbance
Excludes
- Dementia without behavioral disturbance (F02.80)
Clinical Validation Requirements
- Cognitive decline with documented behavioral symptoms
Coding Notes
Ensure behavioral symptoms are documented.

F02.80Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Dementia with Alzheimer's 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 inadequate treatment planning., Regulatory: Non-compliance with documentation standards., Financial: Potential loss of reimbursement for behavioral disturbance.
Mitigation Strategy
Train staff on importance of documenting behavioral symptoms., Use checklists to ensure all symptoms are recorded.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces accuracy of patient data.
Mitigation Strategy
Always document and code specific details such as onset and behavioral symptoms.
Impact
Risk of audits if behavioral symptoms are not documented when coding F02.81.
Mitigation Strategy
Implement regular documentation audits and staff training.
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.
