| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R80.0 | Isolated proteinuria | Use when proteinuria is detected without any accompanying hematuria or renal pathology. |
|
| R80.1 | Persistent proteinuria | Use when proteinuria is persistent over multiple tests. |
|
| R80.2 | Orthostatic proteinuria | Use when proteinuria is confirmed to be orthostatic. |
|
| R80.3 | Bence Jones proteinuria | Use when Bence Jones proteins are confirmed in the urine. |
|
| R80.9 | Unspecified proteinuria | Use when proteinuria is detected but not further 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.

Primary ICD-10-CM Codes for proteinuria
Decision Criteria
clinical Criteria
- Proteinuria without hematuria or renal pathology
Applicable To
- Proteinuria without hematuria
- Asymptomatic proteinuria
Excludes
- Proteinuria with known renal pathology
Clinical Validation Requirements
- Urine protein >150 mg/24h without hematuria
- No renal pathology on imaging or biopsy
Code-Specific Risks
- Misclassification if renal pathology is later identified
Coding Notes
- Ensure no underlying renal condition is present before using this code.
R80.1 - Persistent proteinuria
Use when proteinuria is persistent over multiple tests.
Applicable To
- Proteinuria confirmed on multiple tests
Excludes
- Transient proteinuria
Clinical Validation Requirements
- Proteinuria confirmed on at least two separate occasions over 3-6 months
Coding Notes
Document persistence clearly with dates of tests.
R80.2 - Orthostatic proteinuria
Use when proteinuria is confirmed to be orthostatic.
Applicable To
- Proteinuria that resolves when supine
Excludes
- Persistent proteinuria
Clinical Validation Requirements
- Proteinuria present in upright position, absent when supine
Coding Notes
Ensure documentation includes positional testing results.
R80.3 - Bence Jones proteinuria
Use when Bence Jones proteins are confirmed in the urine.
Applicable To
- Presence of monoclonal light chains in urine
Excludes
- Non-monoclonal proteinuria
Clinical Validation Requirements
- Urine immunofixation showing monoclonal light chains
Coding Notes
Confirmatory testing is essential before coding.
R80.9 - Unspecified proteinuria
Use when proteinuria is detected but not further specified.
Applicable To
- Proteinuria not otherwise specified
Excludes
- Specific types of proteinuria
Clinical Validation Requirements
- Initial finding of proteinuria without further specification
Coding Notes
Avoid using as a principal diagnosis if a more specific code is available.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Proteinuria to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R80.0.
Impact
Clinical: Inaccurate diagnosis and treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.
Mitigation Strategy
Educate clinicians on the importance of detailed documentation., Implement documentation templates.
Impact
Reimbursement: May lead to denied claims if specificity is not provided., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces accuracy of clinical data.
Mitigation Strategy
Ensure documentation specifies the type of proteinuria for accurate coding.
Impact
Frequent use of R80.9 without attempts to specify.
Mitigation Strategy
Encourage detailed documentation and regular 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.
