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

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Essential facts and insights about Renal Carcinoma
Primary ICD-10-CM Codes for renal carcinoma
Decision Criteria
clinical Criteria
- Confirmed right kidney mass via imaging or biopsy
Applicable To
- Right kidney involvement
Excludes
- Malignant neoplasm of renal pelvis (C65.1)
Clinical Validation Requirements
- Biopsy-confirmed clear cell renal cell carcinoma
- Imaging showing right kidney mass
Code-Specific Risks
- Misidentifying laterality
- Incorrect histologic subtype documentation
Coding Notes
- Ensure laterality is documented clearly to avoid using unspecified codes.
C64.2 - Malignant neoplasm of left kidney, except renal pelvis
Use when the left kidney is confirmed to have a malignant neoplasm, excluding the renal pelvis.
Applicable To
- Left kidney involvement
Excludes
- Malignant neoplasm of renal pelvis (C65.2)
Clinical Validation Requirements
- Biopsy-confirmed papillary renal cell carcinoma
- Imaging showing left kidney mass
Coding Notes
Ensure laterality is documented clearly to avoid using unspecified codes.
C64.9 - Malignant neoplasm of unspecified kidney, except renal pelvis
Use when the laterality of the kidney involvement is not specified.
Applicable To
- Unspecified laterality
Excludes
- Malignant neoplasm of renal pelvis (C65.9)
Clinical Validation Requirements
- Biopsy-confirmed renal cell carcinoma without specified laterality
- Imaging showing renal mass without specified laterality
Coding Notes
Avoid using unspecified codes when laterality is documented elsewhere.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Malignant neoplasm of right renal pelvis
C65.1Malignant neoplasm of left renal pelvis
C65.2Malignant neoplasm of unspecified renal pelvis
C65.9Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Renal Carcinoma 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 affect treatment decisions., Regulatory: Non-compliance with documentation standards., Financial: Potential for claim denials.
Mitigation Strategy
Ensure histologic subtype is included in pathology reports., Cross-check clinical notes for completeness.
Impact
Reimbursement: May lead to denied claims or reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Ensure laterality is clearly documented and use specific codes.
Impact
Failure to document laterality can lead to incorrect coding.
Mitigation Strategy
Implement mandatory laterality checks in clinical 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.
