| R91.8 | Other nonspecific abnormal finding of lung field | Use for initial findings of a lung mass on imaging when no specific diagnosis is confirmed. |
|
| C34.90 | Malignant neoplasm of unspecified part of unspecified bronchus or lung | Use when a lung mass is confirmed to be malignant, but specific site or laterality is not documented. |
|
| D14.30 | Benign neoplasm of unspecified bronchus and lung | Use when a lung mass is confirmed to be benign. |

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Mass on Lung to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R91.8.
Impact
Clinical: Inaccurate treatment planning., Regulatory: Potential audit issues., Financial: Incorrect reimbursement.
Mitigation Strategy
Verify imaging reports for laterality., Include laterality in documentation.
Impact
Reimbursement: Incorrect DRG assignment leading to potential underpayment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient records.
Mitigation Strategy
Replace R91.8 with the appropriate C34.xx code.
Impact
Lack of specificity in coding lung masses can lead to audits.
Mitigation Strategy
Ensure detailed documentation of imaging and pathology findings.
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.
