| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C34.11 | Malignant neoplasm of upper lobe, right bronchus or lung | Use when adenocarcinoma is confirmed in the right upper lobe of the lung. |
|
| C78.01 | Secondary malignant neoplasm of right lung | Use when adenocarcinoma has metastasized to the right lung. |

Applicable To
- Adenocarcinoma of right upper lobe
Excludes
- Benign neoplasms of lung
Clinical Validation Requirements
- Histological confirmation of adenocarcinoma
- Imaging showing mass in right upper lobe
Code-Specific Risks

C78.01 - Secondary malignant neoplasm of right lung
Use when adenocarcinoma has metastasized to the right lung.
Applicable To
- Metastatic adenocarcinoma to right lung
Excludes
- Primary lung cancer
Clinical Validation Requirements
- Evidence of metastasis to the right lung from another primary site
Coding Notes
Ensure documentation specifies metastasis to the lung.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Adenocarcinoma Lung Cancer to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C34.11.
Impact
Clinical: Impacts treatment decisions and surgical planning., Regulatory: Non-compliance with coding guidelines., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Ensure imaging and pathology reports specify the affected lobe., Train staff on the importance of detailed documentation.
Impact
Reimbursement: May lead to lower reimbursement due to lack of specificity., Compliance: Non-compliance with coding standards., Data Quality: Decreases accuracy of cancer registry data.
Mitigation Strategy
Ensure histological confirmation is attempted and documented.
Impact
Risk of audit if histological confirmation is not documented.
Mitigation Strategy
Ensure all diagnoses are supported by pathology reports.
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.
