| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| B02.22 | Postherpetic trigeminal neuralgia | Use when the patient presents with facial pain following herpes zoster affecting the trigeminal nerve. |
|
| B02.29 | Other postherpetic neuralgia | Use for PHN affecting nerves other than the trigeminal nerve. |

Primary ICD-10-CM Codes for postherpetic neuralgia
Decision Criteria
clinical Criteria
- Pain in trigeminal nerve distribution post-herpes zoster
Applicable To
- Trigeminal nerve involvement
Excludes
- Non-trigeminal postherpetic neuralgia
Clinical Validation Requirements
- Persistent pain in trigeminal nerve distribution 90+ days post-herpes zoster resolution
Code-Specific Risks
- Misclassification with other facial pain syndromes
Coding Notes
- Ensure documentation specifies trigeminal nerve involvement.
B02.29 - Other postherpetic neuralgia
Use for PHN affecting nerves other than the trigeminal nerve.
Applicable To
- Non-trigeminal nerve involvement
Excludes
- Trigeminal neuralgia
Clinical Validation Requirements
- Pain persisting 120 days after rash resolution in non-trigeminal distribution
Coding Notes
Document specific nerve involvement and duration of pain.
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 Postherpetic 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: Misdiagnosis risk, Regulatory: Non-compliance with documentation standards, Financial: Potential claim denials
Mitigation Strategy
Include pain duration in all PHN notes
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding standards., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use B02.22 or B02.29 depending on nerve involvement.
Impact
Risk of incorrect coding due to lack of specific nerve involvement documentation.
Mitigation Strategy
Require detailed documentation of nerve involvement and pain duration.
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.
