| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| B02.22 | Postherpetic trigeminal neuralgia | Use when there is confirmed trigeminal nerve involvement post-herpes zoster. |
|
| B02.29 | Other postherpetic nervous system involvement | Use for postherpetic neuralgia affecting non-trigeminal dermatomes. |
|
| G53.0 | Postzoster neuralgia | Use when provider explicitly uses 'postzoster' terminology. |

Decision Criteria
clinical Criteria
- Pain in trigeminal nerve distribution persisting ≥90 days post-herpes zoster
Applicable To
- Trigeminal nerve involvement post-herpes zoster
Excludes
- Trigeminal neuralgia unrelated to herpes zoster (G50.0)
Clinical Validation Requirements
- Persistent pain in trigeminal nerve distribution for ≥90 days post-herpes zoster
- MRI showing trigeminal ganglion enhancement
Code-Specific Risks
- Incorrect use without specifying trigeminal nerve involvement
Coding Notes
- Ensure documentation specifies trigeminal nerve involvement and duration of pain.
B02.29 - Other postherpetic nervous system involvement
Use for postherpetic neuralgia affecting non-trigeminal dermatomes.
Applicable To
- Non-trigeminal nerve involvement post-herpes zoster
Excludes
- Trigeminal neuralgia (B02.22)
Clinical Validation Requirements
- Persistent neuropathic pain in non-trigeminal dermatomes for ≥90 days post-herpes zoster
Coding Notes
Ensure documentation specifies the affected dermatomes and duration of pain.
G53.0 - Postzoster neuralgia
Use when provider explicitly uses 'postzoster' terminology.
Applicable To
- Postzoster neuralgia
Clinical Validation Requirements
- Provider documentation using 'postzoster' terminology
Coding Notes
Ensure provider's terminology aligns with code usage.
Ancillary Codes

B02.21Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Post-Zoster Neuralgia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code B02.22.
Impact
Clinical: Inaccurate diagnosis of postherpetic neuralgia., Regulatory: Non-compliance with coding standards., Financial: Potential loss of reimbursement.
Mitigation Strategy
Use templates that prompt for pain duration., Educate providers on documentation requirements.
Impact
Reimbursement: May lead to incorrect DRG assignment, affecting reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation clearly states trigeminal nerve involvement.
Impact
Reimbursement: Incorrect code may affect reimbursement rates., Compliance: Potential audit risk due to coding errors., Data Quality: Misrepresentation of clinical condition.
Mitigation Strategy
Use G53.0* only if 'postzoster' terminology is used by the provider.
Impact
Using codes without proper documentation of nerve involvement or pain duration.
Mitigation Strategy
Implement regular audits and provider education.
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.
