R91Primary Range
Abnormal findings on diagnostic imaging of lung
This range is used for coding abnormal findings specifically related to the lung, such as nodules or infiltrates.
Abnormal findings on diagnostic imaging of other specified body structures
This range is used for coding abnormal findings in non-lung chest structures, such as the mediastinum or chest wall.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R91.1 | Solitary pulmonary nodule | Use when a CT chest report identifies a solitary pulmonary nodule with specific size criteria. |
|
| R93.8 | Abnormal findings on diagnostic imaging of other specified body structures | Use when CT findings are related to non-lung structures such as the mediastinum or chest wall. |

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
- Presence of a solitary pulmonary nodule ≥6 mm on CT
Applicable To
- Solitary pulmonary nodule
Excludes
- Malignant neoplasm of bronchus and lung (C34.-)
Clinical Validation Requirements
- CT report indicating a solitary pulmonary nodule ≥6 mm
- No prior history of malignancy
Code-Specific Risks
- Incorrectly coding as malignancy without biopsy confirmation
Coding Notes
- Ensure documentation includes nodule size and follow-up recommendations per guidelines.
R93.8 - Abnormal findings on diagnostic imaging of other specified body structures
Use when CT findings are related to non-lung structures such as the mediastinum or chest wall.
Applicable To
- Mediastinal lymphadenopathy
Excludes
- Specific conditions classified elsewhere
Clinical Validation Requirements
- CT report indicating abnormal findings in non-lung chest structures
Coding Notes
Ensure documentation specifies the structure involved and any follow-up recommendations.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Abnormal CT Chest Findings to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R91.1.
Impact
Clinical: May result in inappropriate follow-up or treatment., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials or reduced reimbursement.
Mitigation Strategy
Ensure detailed documentation of findings, Use structured templates for reporting
Impact
Reimbursement: Incorrect coding can lead to denied claims or incorrect DRG assignment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.
Mitigation Strategy
Ensure the provider documents the impression clearly and confirms malignancy before coding as cancer.
Impact
Risk of coding lung cancer instead of abnormal findings due to unclear documentation.
Mitigation Strategy
Ensure clear documentation of findings and confirmatory tests before coding malignancy.
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.
