| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C64.1 | Malignant neoplasm of right kidney, except renal pelvis | Use when the tumor is located in the right kidney and confirmed as renal cell carcinoma. |
|
| C64.2 | Malignant neoplasm of left kidney, except renal pelvis | Use when the tumor is located in the left kidney and confirmed as renal cell carcinoma. |
|
| C64.9 | Malignant neoplasm of unspecified kidney, except renal pelvis | Use when the laterality of the kidney tumor is not specified or cannot be determined. |

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
- Confirmed diagnosis of renal cell carcinoma in the right kidney
Applicable To
- Right kidney cancer
Excludes
- Malignant neoplasm of renal pelvis (C65.1)
Clinical Validation Requirements
- Imaging showing a solid mass in the right kidney
- Pathology report confirming renal cell carcinoma
Code-Specific Risks
- Incorrect laterality documentation
Coding Notes
- Ensure laterality is documented to avoid using unspecified codes.
C64.2 - Malignant neoplasm of left kidney, except renal pelvis
Use when the tumor is located in the left kidney and confirmed as renal cell carcinoma.
Applicable To
- Left kidney cancer
Excludes
- Malignant neoplasm of renal pelvis (C65.2)
Clinical Validation Requirements
- Imaging showing a solid mass in the left kidney
- Pathology report confirming renal cell carcinoma
Coding Notes
Ensure laterality is documented to avoid using unspecified codes.
C64.9 - Malignant neoplasm of unspecified kidney, except renal pelvis
Use when the laterality of the kidney tumor is not specified or cannot be determined.
Applicable To
- Unspecified kidney cancer
Excludes
- Malignant neoplasm of renal pelvis (C65.9)
Clinical Validation Requirements
- Imaging showing a solid mass in the kidney without specified laterality
- Pathology report confirming renal cell carcinoma
Coding Notes
Avoid using this code if laterality is documented.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Renal Cell Cancer to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C64.1.
Impact
Clinical: May lead to inappropriate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims or incorrect reimbursement.
Mitigation Strategy
Always verify laterality in imaging and pathology reports, Educate staff on the importance of laterality documentation
Impact
Reimbursement: May lead to incorrect DRG assignment and affect reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data collection for kidney cancer statistics.
Mitigation Strategy
Use C64.1 or C64.2 based on the documented laterality.
Impact
High risk of audit if laterality is not documented for kidney cancer cases.
Mitigation Strategy
Implement a checklist for documentation that includes laterality verification.
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.
