| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C34.11 | Malignant neoplasm of upper lobe, right bronchus or lung | Use when squamous cell carcinoma is confirmed in the upper lobe of the right lung. |
|
| C34.32 | Malignant neoplasm of lower lobe, left bronchus or lung | Use when squamous cell carcinoma is confirmed in the lower lobe of the left lung. |

Primary ICD-10-CM Codes for squamous cell carcinoma of lung
Decision Criteria
clinical Criteria
- Confirmed squamous cell carcinoma in the upper lobe of the right lung
documentation Criteria
- Documentation must specify 'upper lobe, right lung' and 'squamous cell carcinoma'
Applicable To
- Squamous cell carcinoma of upper lobe, right lung
Excludes
- Benign neoplasm of lung (D14.3)
Clinical Validation Requirements
- Biopsy confirming squamous cell carcinoma
- Imaging showing mass in upper lobe, right lung
Code-Specific Risks
- Incorrect laterality documentation leading to miscoding
Coding Notes
- Ensure documentation specifies laterality and subsite to avoid unspecified codes.
C34.32 - Malignant neoplasm of lower lobe, left bronchus or lung
Use when squamous cell carcinoma is confirmed in the lower lobe of the left lung.
Applicable To
- Squamous cell carcinoma of lower lobe, left lung
Excludes
- Benign neoplasm of lung (D14.3)
Clinical Validation Requirements
- Biopsy confirming squamous cell carcinoma
- Imaging showing mass in lower lobe, left lung
Coding Notes
Ensure documentation specifies laterality and subsite to avoid unspecified codes.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Squamous Cell Carcinoma of the Lung 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 decisions., Regulatory: Non-compliance with coding guidelines., Financial: Potential for claim denials or reduced reimbursement.
Mitigation Strategy
Ensure histology is documented in all relevant reports., Use templates that prompt for histology type.
Impact
Reimbursement: Incorrect coding may lead to denied claims or incorrect DRG assignment., Compliance: Misclassification of the cancer type can lead to compliance issues., Data Quality: Impacts the accuracy of cancer registry data.
Mitigation Strategy
Confirm the anatomic site in documentation to ensure correct coding under C34.XX.
Impact
Reimbursement: Unspecified codes may result in lower reimbursement rates., Compliance: Inadequate documentation can lead to audit issues., Data Quality: Affects the precision of clinical data and outcomes tracking.
Mitigation Strategy
Ensure documentation specifies right or left lung to avoid unspecified codes.
Impact
Use of unspecified codes when specific codes are available.
Mitigation Strategy
Implement documentation checks to ensure laterality and site are specified.
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.
