| C78.01 | Secondary malignant neoplasm of right lung | Use when metastasis to the right lung is confirmed. |
|
| C78.02 | Secondary malignant neoplasm of left lung | Use when metastasis to the left lung is confirmed. |

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

Primary ICD-10-CM Codes for secondary lung cancer
Decision Criteria
clinical Criteria
- Confirmed metastasis to lung via imaging or biopsy.
documentation Criteria
- Documentation must specify 'metastatic to lung'.
Applicable To
- Metastatic cancer to lung, unspecified
Excludes
- Primary lung cancer (C34.xx)
Clinical Validation Requirements
- Imaging showing lung lesion
- Biopsy confirming metastasis
Code-Specific Risks
- Risk of unspecified laterality leading to reduced specificity.
Coding Notes
- Ensure documentation specifies 'metastatic to lung' and not primary lung cancer.
C78.01 - Secondary malignant neoplasm of right lung
Use when metastasis to the right lung is confirmed.
Applicable To
- Metastatic cancer to right lung
Excludes
- Primary lung cancer (C34.xx)
Clinical Validation Requirements
- Imaging showing lesion in right lung
- Biopsy confirming metastasis
Coding Notes
Ensure documentation specifies 'metastatic to right lung'.
C78.02 - Secondary malignant neoplasm of left lung
Use when metastasis to the left lung is confirmed.
Applicable To
- Metastatic cancer to left lung
Excludes
- Primary lung cancer (C34.xx)
Clinical Validation Requirements
- Imaging showing lesion in left lung
- Biopsy confirming metastasis
Coding Notes
Ensure documentation specifies 'metastatic to left lung'.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Secondary Lung Cancer to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C78.00.
Impact
Clinical: Impacts treatment planning and monitoring., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims due to unspecified codes.
Mitigation Strategy
Always document laterality for lung metastases., Use templates that prompt for complete information.
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with ICD-10 coding guidelines., Data Quality: Inaccurate data on cancer prevalence and treatment.
Mitigation Strategy
Use C78.0x codes for metastases to the lung.
Impact
Leads to incorrect DRG assignment and reimbursement issues.
Mitigation Strategy
Train coders on proper sequencing rules and documentation requirements.
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.
