R91Primary Range
Abnormal findings on diagnostic imaging of lung
This range includes codes for abnormal findings on lung imaging, such as X-rays or CT scans, without a confirmed diagnosis.
Neoplasms of uncertain or benign behavior
This range includes codes for benign or uncertain behavior neoplasms found in the lung.
Malignant neoplasm of bronchus and lung
This range includes codes for confirmed malignant neoplasms of the lung.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R91.8 | Other nonspecific abnormal finding of lung field | Use when imaging shows an abnormality without a confirmed diagnosis. |
|
| D14.30 | Benign neoplasm of unspecified part of bronchus and lung | Use when a biopsy confirms a benign lung neoplasm. |
|
| C34.90 | Malignant neoplasm of unspecified part of bronchus or lung | Use when malignancy is confirmed by biopsy or histology. |

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

Decision Criteria
clinical Criteria
- Imaging shows abnormality without specific diagnosis.
Clinical Validation Requirements
- Radiology report indicating abnormal finding without specific diagnosis
- No biopsy or histological confirmation
Code-Specific Risks
- Misclassification if a neoplasm is later confirmed
Coding Notes
- Ensure documentation specifies the abnormal finding and its nonspecific nature.
D14.30 - Benign neoplasm of unspecified part of bronchus and lung
Use when a biopsy confirms a benign lung neoplasm.
Applicable To
- Benign lung tumor
Excludes
- Malignant neoplasm (C34)
Clinical Validation Requirements
- Biopsy confirms benign nature
- Stable imaging over time
Coding Notes
Document biopsy results confirming benign status.
C34.90 - Malignant neoplasm of unspecified part of bronchus or lung
Use when malignancy is confirmed by biopsy or histology.
Applicable To
- Lung cancer
Excludes
- Benign neoplasm (D14.30)
Clinical Validation Requirements
- Biopsy or histology confirms malignancy
- PET scan positive for malignancy
Coding Notes
Ensure documentation includes biopsy or histology results.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Abnormal Lung Imaging Findings to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R91.8.
Impact
Clinical: May lead to inappropriate follow-up or missed diagnosis., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to insufficient documentation.
Mitigation Strategy
Use structured templates for radiology reports, Ensure detailed descriptions of findings
Impact
Reimbursement: Incorrect DRG assignment may occur., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate cancer registry data.
Mitigation Strategy
Ensure malignancy is confirmed by biopsy before using C34.90.
Impact
Coding R91.8 without documented follow-up plan may trigger audits.
Mitigation Strategy
Ensure follow-up recommendations are documented.
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.
