| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C78.02 | Secondary malignant neoplasm of left lung | Use when metastasis to the left lung is confirmed by clinical evidence. |

| C78.00 | Secondary malignant neoplasm of unspecified lung | Use when metastasis to the lung is confirmed but laterality is not specified. |

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

documentation Criteria
- Documentation must specify laterality and primary site if known
Applicable To
- Metastatic cancer to left lung
Excludes
- Primary malignant neoplasm of lung (C34.-)
Clinical Validation Requirements
- Pathology report confirming metastasis
- Radiologic evidence of metastatic lesions
Code-Specific Risks
- Incorrectly coding as primary lung cancer
Coding Notes
- Ensure documentation specifies metastasis and laterality.
C78.00 - Secondary malignant neoplasm of unspecified lung
Use when metastasis to the lung is confirmed but laterality is not specified.
Applicable To
- Metastatic cancer to lung, unspecified
Excludes
- Primary malignant neoplasm of lung (C34.-)
Clinical Validation Requirements
- Radiologic evidence of metastatic lesions without specified laterality
Coding Notes
Ensure documentation specifies metastasis even if laterality is unknown.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Lung Metastases to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C78.02.
Impact
Clinical: Incomplete clinical picture, Regulatory: Non-compliance with coding guidelines, Financial: Potential underpayment
Mitigation Strategy
Always verify primary cancer documentation, Cross-check with oncology reports
Impact
Reimbursement: Incorrect coding may lead to improper reimbursement levels., Compliance: May result in compliance issues during audits., Data Quality: Affects the accuracy of cancer registry data.
Mitigation Strategy
Ensure documentation specifies the metastatic nature of the lung lesion.
Impact
Risk of coding errors due to unspecified laterality or primary site.
Mitigation Strategy
Implement regular training and audits on documentation and coding practices.
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.
