| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G20 | Parkinson's disease | Use as the primary code for Parkinson's disease diagnosis. |
|
| F02.81 | Dementia in other diseases classified elsewhere with behavioral disturbance | Use when dementia in Parkinson's disease includes behavioral disturbances. |
|
| F02.80 | Dementia in other diseases classified elsewhere without behavioral disturbance | Use when dementia in Parkinson's disease lacks 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 parkinson's dementia
Decision Criteria
clinical Criteria
- Presence of bradykinesia and at least one other motor symptom.
Applicable To
- Idiopathic Parkinson's disease
- Primary Parkinsonism
Excludes
- Secondary Parkinsonism (G21.-)
Clinical Validation Requirements
- Bradykinesia plus one of: resting tremor, rigidity, postural instability
Code-Specific Risks
- Ensure motor symptoms are documented to differentiate from secondary Parkinsonism.
Coding Notes
- Ensure clear documentation of Parkinson's disease diagnosis.
F02.81 - Dementia in other diseases classified elsewhere with behavioral disturbance
Use when dementia in Parkinson's disease includes behavioral disturbances.
Applicable To
- Dementia with behavioral disturbances such as aggression, hallucinations
Excludes
- Dementia without behavioral disturbance (F02.80)
Clinical Validation Requirements
- Documented behavioral disturbances like aggression or hallucinations.
Coding Notes
Behavioral disturbances must be explicitly documented.
F02.80 - Dementia in other diseases classified elsewhere without behavioral disturbance
Use when dementia in Parkinson's disease lacks behavioral disturbances.
Applicable To
- Dementia without behavioral disturbances
Excludes
- Dementia with behavioral disturbance (F02.81)
Clinical Validation Requirements
- Absence of documented behavioral disturbances.
Coding Notes
Document explicitly that no behavioral disturbances are present.
Differential Codes

G31.83Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Parkinson's Dementia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G20.
Impact
Clinical: Inaccurate clinical picture., Regulatory: Non-compliance with coding standards., Financial: Potential for lower reimbursement.
Mitigation Strategy
Ensure thorough documentation of all symptoms.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Verify the timing of cognitive and motor symptoms; use G20 and F02.81 for Parkinson's dementia.
Impact
Failure to document behavioral disturbances can lead to incorrect coding.
Mitigation Strategy
Ensure all behavioral symptoms are documented in detail.
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.
