| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R31.21 | Asymptomatic microscopic hematuria | Use when microscopic hematuria is confirmed without symptoms and no visible blood is present. |
|
| R31.29 | Other microscopic hematuria | Use when microscopic hematuria is symptomatic or associated with risk factors. |

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 microhematuria
Decision Criteria
clinical Criteria
- Confirmed microscopic hematuria on urinalysis
documentation Criteria
- No symptoms reported by the patient
Applicable To
- Persistent asymptomatic microscopic hematuria
Excludes
- Symptomatic microscopic hematuria
Clinical Validation Requirements
- >3 RBC/HPF on microscopy confirmed on two separate occasions
- No visible blood in urine
Code-Specific Risks
- Misclassification if not confirmed by microscopy
- Incorrect use if symptoms are present
Coding Notes
- Ensure documentation specifies asymptomatic status and confirms microscopy results.
R31.29 - Other microscopic hematuria
Use when microscopic hematuria is symptomatic or associated with risk factors.
Applicable To
- Symptomatic microscopic hematuria
Excludes
- Asymptomatic microscopic hematuria
Clinical Validation Requirements
- Microscopic hematuria with symptoms or risk factors such as smoking history
Coding Notes
Document any symptoms or risk factors clearly to support code selection.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Microhematuria to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R31.21.
Impact
Clinical: May lead to misdiagnosis., Regulatory: Fails to meet documentation standards., Financial: Could result in claim denials.
Mitigation Strategy
Always confirm with microscopy.
Impact
Reimbursement: May lead to claim denials due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces data accuracy for patient records.
Mitigation Strategy
Ensure thorough documentation and evaluation to use specific codes like R31.21 or R31.29.
Impact
Risk of audits due to use of unspecified codes.
Mitigation Strategy
Ensure complete documentation and use of specific codes.
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.
