Use when the behavior of the kidney mass is indeterminate.
Clinical Validation Requirements
- Imaging identifies a mass but histology is pending
Coding Notes
Reassess once histology results are available.
N28.89 - Other specified disorders of kidney
Use for benign lesions or other specified kidney disorders.
Applicable To
- Benign complex cyst
Clinical Validation Requirements
- Imaging shows smooth margins, lack of enhancement
Coding Notes
Ensure benign nature is confirmed through imaging.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Mass Left Kidney to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code C64.2.
Impact
Clinical: Leads to less precise clinical data., Regulatory: May not meet coding compliance standards., Financial: Can affect reimbursement rates.
Mitigation Strategy
Ensure histology and imaging are reviewed before coding.
Impact
Reimbursement: Incorrect coding can lead to improper reimbursement., Compliance: May result in compliance issues with coding standards., Data Quality: Affects the accuracy of clinical data.
Mitigation Strategy
Use imaging and histology to confirm diagnosis before coding.
Impact
Coding without histology confirmation can lead to audit issues.
Mitigation Strategy
Ensure biopsy results are available before final coding.
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.
