C34.0-C34.9Primary Range
Malignant neoplasm of bronchus and lung
This range covers primary malignant neoplasms of the lung, categorized by specific lobes and laterality.
Secondary malignant neoplasm of lung
This range is used for coding metastatic lung cancer originating from another primary site.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C34.11 | Malignant neoplasm of upper lobe, right bronchus or lung | Use when a malignant tumor is confirmed in the right upper lobe of the lung. |
|
| C78.02 | Secondary malignant neoplasm of left lung | Use for metastatic lesions in the left lung originating from another primary site. |

Applicable To
- Metastatic carcinoma to left lung
Excludes
- Primary lung cancer (C34.x)
Clinical Validation Requirements

- Primary site documentation
Coding Notes
Ensure primary site is coded and documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Lung Carcinoma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C34.11.
Impact
Clinical: May lead to inappropriate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.
Mitigation Strategy
Ensure detailed documentation of tumor location., Use specific codes whenever possible.
Impact
Reimbursement: Incorrect DRG assignment may affect reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate cancer registry data.
Mitigation Strategy
Verify primary site and document clearly in the medical record.
Impact
Failure to document laterality can lead to incorrect coding.
Mitigation Strategy
Implement mandatory laterality checks in documentation workflows.
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.
