| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R94.4 | Abnormal results of kidney function studies | When lab results show elevated creatinine but CKD is not diagnosed. |
|
| N18.3 | Chronic kidney disease, stage 3 (moderate) | When CKD stage 3 is documented by the provider. |

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Elevated Kidney Function to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R94.4.
Impact
Clinical: Inaccurate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.
Mitigation Strategy
Educate providers on documentation standards., Use templates to guide documentation.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces accuracy of patient data.
Mitigation Strategy
Always use the most specific CKD stage code available.
Impact
Inadequate documentation of CKD stages.
Mitigation Strategy
Implement regular training and audits.
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.
