C34.0-C34.9Primary Range
Malignant neoplasm of bronchus and lung
This range covers all primary malignant neoplasms of the bronchus and lung, including specific lobes and laterality.
Personal history of malignant neoplasm of bronchus and lung
Used for patients with a history of lung cancer, primarily in follow-up care.
Malignant pleural effusion
Used as a secondary code when a malignant pleural effusion is present alongside lung cancer.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C34.11 | Malignant neoplasm of upper lobe, right bronchus or lung | Use when the cancer is confirmed in the right upper lobe of the lung. |
|
| Z85.118 | Personal history of malignant neoplasm of bronchus and lung | Use for follow-up visits when the patient has a history of lung cancer. |

Decision Criteria
clinical Criteria
- Confirmed primary lung cancer in the right upper lobe
Applicable To
- Right upper lobe lung cancer

Code-Specific Risks
- Incorrect laterality documentation
Coding Notes
- Ensure laterality is documented correctly to avoid miscoding.
Z85.118 - Personal history of malignant neoplasm of bronchus and lung
Use for follow-up visits when the patient has a history of lung cancer.
Applicable To
- History of lung cancer
Excludes
- Active lung cancer (C34.XX)
Clinical Validation Requirements
- Documented history of lung cancer treatment
- No current active disease
Coding Notes
Ensure the cancer is not currently active.
Ancillary Codes

J91.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting 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: Potential for incorrect treatment planning., Regulatory: Non-compliance with ICD-10 coding standards., Financial: Claims may be denied or delayed.
Mitigation Strategy
Always document the specific lung lobe affected.
Impact
Reimbursement: Incorrect sequencing can lead to denied claims or reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Always sequence the primary lung cancer code before any secondary or ancillary codes.
Impact
Using Z85.118 for active cancer cases.
Mitigation Strategy
Verify current cancer status before coding.
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.
