R31

Hematuria

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R31 is a billable code used to indicate a diagnosis of hematuria.

Key Diagnostic Point:

Hematuria is defined as the presence of blood in the urine, which can be either gross (visible to the naked eye) or microscopic (detected only through laboratory testing). It is a symptom rather than a diagnosis and can arise from various underlying conditions affecting the urinary tract, kidneys, or bladder. Common causes include urinary tract infections (UTIs), kidney stones, trauma, tumors, and glomerular diseases. The clinical significance of hematuria varies; while it may indicate benign conditions, it can also signal serious pathologies such as malignancies. The diagnostic approach typically involves a thorough patient history, physical examination, urinalysis, and possibly imaging studies or cystoscopy to identify the source of bleeding. Accurate documentation of hematuria is crucial for appropriate coding and management, as it guides further diagnostic and therapeutic interventions.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of potential underlying causes
  • Need for thorough diagnostic workup
  • Differentiation between gross and microscopic hematuria
  • Documentation of associated symptoms and findings

Audit Risk Factors

  • Inadequate documentation of the type of hematuria
  • Failure to specify associated symptoms
  • Misclassification of hematuria as a diagnosis rather than a symptom
  • Lack of follow-up documentation for underlying conditions

Specialty Focus

Internal Medicine

Documentation Requirements

Detailed patient history, including duration and characteristics of hematuria, associated symptoms, and any relevant medical history.

Common Clinical Scenarios

Patients presenting with hematuria due to UTIs, kidney stones, or glomerulonephritis.

Billing Considerations

Ensure comprehensive documentation of diagnostic tests performed and their results.

Emergency Medicine

Documentation Requirements

Acute care documentation must include vital signs, initial assessment findings, and any immediate interventions.

Common Clinical Scenarios

Patients with acute hematuria due to trauma or severe infections.

Billing Considerations

Rapid assessment and documentation of potential life-threatening causes are critical.

Frequently Asked Questions

What is the difference between gross and microscopic hematuria?

Gross hematuria is visible to the naked eye, while microscopic hematuria is detected only through laboratory analysis. Both require further evaluation to determine the underlying cause.
