| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R35.0 | Frequency of micturition | Use when the patient experiences frequent urination without increased urine volume. |
|
| R35.1 | Nocturnal polyuria | Use when nocturnal urine output is significantly higher than daytime output. |
|
| R35.8 | Other polyuria | Use when there is increased urine volume without a specific cause identified. |

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 nocturnal urine output is significantly higher than daytime output.
Applicable To
- Excessive urination at night
Excludes
- Nocturia (R35.0)
Clinical Validation Requirements
- Documented nocturnal urine output exceeding 33% of total daily output
Coding Notes
Ensure nocturnal volume is documented.
R35.8 - Other polyuria
Use when there is increased urine volume without a specific cause identified.
Applicable To
- Polyuria NOS
Excludes
- Diabetes insipidus (E23.2)
Clinical Validation Requirements

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Polyuria to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R35.0.
Impact
Clinical: Inaccurate diagnosis and treatment planning., Regulatory: Potential for audit failures., Financial: Loss of reimbursement due to incorrect coding.
Mitigation Strategy
Implement standard protocols for urine volume measurement.
Impact
Reimbursement: Incorrect coding may lead to lower reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure urine volume is documented to differentiate between frequency and polyuria.
Impact
Failure to code underlying conditions first can lead to audits.
Mitigation Strategy
Educate staff on proper sequencing rules.
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.
