Complete code families applicable to Renal Tumor
C64-C65Primary Range
Malignant neoplasms of kidney, except renal pelvis
This range includes primary malignant neoplasms of the kidney, which are the most common types of renal tumors.
Secondary malignant neoplasm of kidney
This code is used for metastatic cancer to the kidney, not primary renal tumors.
Benign neoplasm of kidney
This code is used for benign renal tumors, which must be differentiated from malignant neoplasms.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| C64.1 | Malignant neoplasm of right kidney, except renal pelvis | Use when a malignant tumor is confirmed in the right kidney. |
|
| C64.2 | Malignant neoplasm of left kidney, except renal pelvis | Use when a malignant tumor is confirmed in the left kidney. |
|
| C64.9 | Malignant neoplasm of unspecified kidney, except renal pelvis | Use when laterality is not documented 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.

Primary ICD-10-CM Codes for renal tumor
Decision Criteria
clinical Criteria

documentation Criteria
- Documentation must specify 'right kidney' and exclude renal pelvis involvement.
Applicable To
- Right kidney cancer
- Right renal cell carcinoma
Excludes
- Malignant neoplasm of renal pelvis (C65.1)
Clinical Validation Requirements
- Imaging confirming mass in right kidney
- Biopsy confirming renal cell carcinoma
Code-Specific Risks
- Incorrect laterality documentation
- Confusion with renal pelvis neoplasm
Coding Notes
- Ensure laterality is documented to avoid unspecified coding.
C64.2 - Malignant neoplasm of left kidney, except renal pelvis
Use when a malignant tumor is confirmed in the left kidney.
Applicable To
- Left kidney cancer
- Left renal cell carcinoma
Excludes
- Malignant neoplasm of renal pelvis (C65.2)
Clinical Validation Requirements
- Imaging confirming mass in left kidney
- Biopsy confirming renal cell carcinoma
Coding Notes
Ensure laterality is documented to avoid unspecified coding.
C64.9 - Malignant neoplasm of unspecified kidney, except renal pelvis
Use when laterality is not documented or cannot be determined.
Applicable To
- Kidney cancer, unspecified
- Renal cell carcinoma, unspecified
Excludes
- Malignant neoplasm of renal pelvis (C65.9)
Clinical Validation Requirements
- General imaging or biopsy confirming renal cell carcinoma without specified laterality
Coding Notes
Query for laterality if possible to avoid unspecified coding.
Ancillary Codes

Personal history of malignant neoplasm of kidney
Z85.3Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

C65.2Malignant neoplasm of unspecified renal pelvis
C65.9Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Renal Tumor 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 decisions., Regulatory: Increased audit risk., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Always document laterality in clinical notes., Verify imaging reports for laterality.
Impact
Reimbursement: Reduced reimbursement due to unspecified codes., Compliance: Increased risk of audit due to lack of specificity., Data Quality: Decreased data accuracy and quality.
Mitigation Strategy
Always document and code the laterality when known.
Impact
Reimbursement: Incorrect DRG assignment affecting payment., Compliance: Non-compliance with coding guidelines., Data Quality: Misleading clinical data.
Mitigation Strategy
Ensure documentation specifies the exact location of the tumor.
Impact
Coding without specifying laterality increases audit risk.
Mitigation Strategy
Ensure laterality is documented in all relevant reports.
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.
