| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R34 | Anuria and Oliguria | Use when decreased urine output is documented without a more specific renal diagnosis. |
|
| N17.9 | Acute kidney failure, unspecified | Use when acute kidney injury is confirmed but 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.

Use when acute kidney injury is confirmed but not specified.
Applicable To
- Acute renal failure
Excludes
- Chronic kidney disease (N18.-)
Clinical Validation Requirements
- Increase in serum creatinine by ≥0.3 mg/dL within 48 hours
- Urine output <0.5 mL/kg/hr for 6 hours
Coding Notes
Ensure AKI criteria are met and documented.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Decreased Urine Output to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R34.
Impact
Clinical: Inadequate clinical picture of renal function., Regulatory: Potential for coding non-compliance., Financial: Risk of claim denials due to insufficient documentation.
Mitigation Strategy
Use standardized templates for documentation., Educate staff on documentation requirements.
Impact
Reimbursement: Incorrect sequencing can affect DRG assignment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Code N17.x as primary and R34 as secondary.
Impact
Inadequate documentation of urine output can lead to audit findings.
Mitigation Strategy
Implement comprehensive documentation templates.
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.
