| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G62.9 | Unspecified polyneuropathy | Use when the etiology of polyneuropathy is unknown after thorough evaluation. |
|
| G63 | Polyneuropathy in diseases classified elsewhere | Use when polyneuropathy is secondary to a documented systemic disease. |
|
| E11.42 | Type 2 diabetes mellitus with diabetic polyneuropathy | Use when diabetes is confirmed as the cause of polyneuropathy. |

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

Essential facts and insights about Polyneuropathy
Primary ICD-10-CM Codes for polyneuropathy
Decision Criteria
clinical Criteria
- No identifiable cause after comprehensive workup
Applicable To
- Peripheral neuropathy NOS
Excludes
- Diabetic polyneuropathy (E11.42)
Clinical Validation Requirements
- EMG/NCS confirming neuropathy
- Exclusion of specific causes such as diabetes, toxins, or nutritional deficiencies
Code-Specific Risks
- Using this code when a more specific cause is identified can lead to audit issues.
Coding Notes
- Ensure all potential causes are ruled out before using this unspecified code.
G63 - Polyneuropathy in diseases classified elsewhere
Use when polyneuropathy is secondary to a documented systemic disease.
Clinical Validation Requirements
- Documentation linking polyneuropathy to a specific systemic disease
Coding Notes
Always sequence the underlying condition code first.
E11.42 - Type 2 diabetes mellitus with diabetic polyneuropathy
Use when diabetes is confirmed as the cause of polyneuropathy.
Applicable To
- Diabetic neuropathy
Clinical Validation Requirements
- HbA1c ≥6.5%
- Nerve conduction studies showing diabetic pattern
Coding Notes
This is a combination code and does not require additional codes for the neuropathy.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Polyneuropathy to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G62.9.
Impact
Clinical: Leads to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.
Mitigation Strategy
Provide detailed clinical notes., Use specific terminology linking symptoms to conditions.
Impact
Reimbursement: Incorrect coding can lead to lower reimbursement., Compliance: May result in non-compliance with coding guidelines., Data Quality: Affects the accuracy of clinical data.
Mitigation Strategy
Use E11.42 when diabetes is the confirmed cause.
Impact
Using unspecified codes when a specific code is available.
Mitigation Strategy
Ensure thorough documentation and use of specific codes.
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.
