Code Description

ICD-10 N02.3 is a billable code used to indicate a diagnosis of recurrent and persistent hematuria with diffuse mesangial proliferative glomerulonephritis.

Key Diagnostic Point:

N02.3 refers to a condition characterized by recurrent and persistent hematuria, which is the presence of blood in the urine, alongside diffuse mesangial proliferative glomerulonephritis (GN). This type of GN is marked by an increase in mesangial cells and matrix within the glomeruli, leading to impaired kidney function. Patients typically present with symptoms such as hematuria, proteinuria, and possible hypertension. The condition may arise from various underlying causes, including autoimmune disorders, infections, or systemic diseases. Diagnosis often involves renal biopsy, which reveals mesangial proliferation and may show immune complex deposition. Management typically includes controlling blood pressure, addressing underlying causes, and possibly using immunosuppressive therapy. Regular monitoring of renal function and urinalysis is essential to assess disease progression and response to treatment.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of nephrology terminology and conditions.
  • Differentiation from other types of glomerulonephritis.
  • Need for accurate documentation of hematuria and proteinuria.
  • Potential overlap with other renal codes.

Audit Risk Factors

  • Inadequate documentation of hematuria severity.
  • Failure to document renal biopsy findings.
  • Lack of clarity on underlying causes of glomerulonephritis.
  • Inconsistent coding of associated conditions.

Specialty Focus

Medical Specialties

Nephrology

Documentation Requirements

Detailed clinical notes on hematuria, proteinuria, and renal function tests.

Common Clinical Scenarios

Patients presenting with unexplained hematuria, recurrent urinary tract infections, or renal insufficiency.

Billing Considerations

Ensure that all relevant lab results and imaging studies are included in the documentation.

Pathology

Documentation Requirements

Comprehensive reports on renal biopsy findings, including histological analysis.

Common Clinical Scenarios

Biopsy evaluations for patients with suspected glomerulonephritis.

Billing Considerations

Pathology reports must clearly indicate the type of glomerular disease and any associated findings.

Coding Guidelines

Inclusion Criteria

Use N02.3 When
  • Follow the official ICD
  • CM coding guidelines, ensuring that the diagnosis is supported by clinical documentation
  • Include specific details about hematuria and renal biopsy findings

Exclusion Criteria

Do NOT use N02.3 When
  • Exclude codes that do not specify glomerulonephritis or are unrelated to the patient's condition

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of glomerulonephritis, improving the accuracy of diagnoses and treatment tracking. N02.3 provides a clear distinction for recurrent hematuria associated with a specific type of glomerulonephritis.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of glomerulonephritis, improving the accuracy of diagnoses and treatment tracking. N02.3 provides a clear distinction for recurrent hematuria associated with a specific type of glomerulonephritis.

Reimbursement & Billing Impact

Frequently Asked Questions

What is the significance of mesangial proliferation in glomerulonephritis?

Mesangial proliferation indicates an inflammatory response within the glomeruli, which can lead to impaired kidney function and is a hallmark of certain types of glomerulonephritis.
