Complete code families applicable to Left Renal Mass
C64-C65Primary Range
Malignant neoplasms of kidney, except renal pelvis
This range includes codes for malignant neoplasms of the kidney, which are primary for coding left renal masses when malignancy is confirmed.
Benign and uncertain behavior neoplasms of the urinary organs
This range includes codes for benign and uncertain behavior neoplasms, applicable when the behavior of the renal mass is not confirmed as malignant.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C64.2 | Malignant neoplasm of left kidney, except renal pelvis | Use when a left renal mass is confirmed as malignant through biopsy and imaging. |
|
| D30.02 | Benign neoplasm of left kidney | Use when a left renal mass is confirmed as benign through biopsy. |
|
| D41.02 | Neoplasm of uncertain behavior of left kidney | Use when the behavior of a left renal mass is uncertain and cannot be classified as benign or malignant. |

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
- Biopsy confirms malignant neoplasm
documentation Criteria
- Imaging shows enhancement consistent with malignancy
Applicable To
- Renal cell carcinoma of left kidney
Excludes
- Malignant neoplasm of renal pelvis (C65.2)
Clinical Validation Requirements
- Histologic confirmation of malignancy
- Imaging showing enhancement >15-20 HU
Code-Specific Risks
- Incorrectly coding as unspecified when laterality is known
Coding Notes
- Ensure documentation specifies laterality and confirms malignancy.
D30.02 - Benign neoplasm of left kidney
Use when a left renal mass is confirmed as benign through biopsy.
Applicable To
- Angiomyolipoma of left kidney
Excludes
- Malignant neoplasm of kidney (C64.2)
Clinical Validation Requirements
- Biopsy confirms benign nature
- Imaging shows homogeneous, non-enhancing mass
Coding Notes
Ensure biopsy results are documented to confirm benign status.
D41.02 - Neoplasm of uncertain behavior of left kidney
Use when the behavior of a left renal mass is uncertain and cannot be classified as benign or malignant.
Applicable To
- Indeterminate renal mass
Excludes
- Malignant neoplasm of kidney (C64.2)
- Benign neoplasm of kidney (D30.02)
Clinical Validation Requirements
- Biopsy inconclusive
- Imaging shows indeterminate features
Coding Notes
Document imaging and biopsy findings thoroughly to support uncertainty.
Ancillary Codes

D30.02Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Left Renal Mass to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C64.2.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Fails to meet documentation standards., Financial: Can affect reimbursement due to incorrect coding.
Mitigation Strategy
Ensure all imaging reports are detailed and included in the patient record., Train staff on the importance of comprehensive documentation.
Impact
Reimbursement: May lead to incorrect DRG assignment and reimbursement issues., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces data accuracy for clinical and research purposes.
Mitigation Strategy
Always specify the laterality (e.g., C64.2 for left kidney).
Impact
Reimbursement: Incorrect coding can affect DRG and reimbursement., Compliance: Fails to meet documentation standards., Data Quality: Impacts clinical decision-making and research data.
Mitigation Strategy
Ensure biopsy results are documented to confirm malignancy or benign nature.
Impact
Coding unspecified kidney when laterality is documented.
Mitigation Strategy
Implement checks to ensure laterality is always specified in documentation.
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.
