Excludes
- Asymptomatic hematuria (R31.21)
Clinical Validation Requirements
- Urinalysis showing ≥3 RBC/HPF
- Presence of symptoms such as dysuria
Coding Notes
Ensure documentation specifies symptoms and confirms microscopy.

Z79.01Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Microscopic Hematuria to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R31.21.
Impact
Clinical: Leads to misdiagnosis., Regulatory: Fails to meet documentation standards., Financial: Potential claim denials.
Mitigation Strategy
Always confirm with microscopy.
Impact
Reimbursement: May lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data.
Mitigation Strategy
Confirm with microscopy before coding.
Impact
Coding based on dipstick results alone.
Mitigation Strategy
Ensure all hematuria codes are supported by urinalysis.
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.
