| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G20 | Parkinson's Disease | Use for confirmed idiopathic Parkinson's disease without specifying complications. |
|
| G20.B2 | Parkinson's disease with dyskinesia and fluctuations | Use when both dyskinesia and motor fluctuations are documented. |

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
- Confirmed idiopathic Parkinson's with classic symptoms
Applicable To
- Idiopathic Parkinsonism
Clinical Validation Requirements
- Presence of bradykinesia, rigidity, resting tremor
- Positive response to levodopa
Code-Specific Risks
- Misclassification if secondary causes are not ruled out
Coding Notes
- Ensure idiopathic nature is documented to avoid misclassification.
G20.B2 - Parkinson's disease with dyskinesia and fluctuations
Use when both dyskinesia and motor fluctuations are documented.
Applicable To
- Parkinson's with motor complications
Clinical Validation Requirements
- Documented dyskinesia and wearing-off episodes
Coding Notes
Ensure detailed documentation of motor complications.
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.

G31.83Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Parkinson's Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G20.
Impact
Clinical: Inadequate treatment planning, Regulatory: Non-compliance with coding standards, Financial: Potential claim denials
Mitigation Strategy
Use specific clinical terms, Document response to treatment
Impact
Reimbursement: Potential claim denial or reduced payment, Compliance: Non-compliance with CMS guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Always sequence G20 before F02.80/F02.81
Impact
Inadequate documentation of motor symptoms can lead to audit issues.
Mitigation Strategy
Ensure thorough documentation of all motor symptoms and treatment responses.
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.
