Code Description

ICD-10 N02.6 is a billable code used to indicate a diagnosis of recurrent and persistent hematuria with dense deposit disease.

Key Diagnostic Point:

Recurrent and persistent hematuria with dense deposit disease is a condition characterized by the presence of blood in the urine (hematuria) that occurs repeatedly and is associated with dense deposit disease (DDD), a rare form of kidney disease. DDD is a type of membranoproliferative glomerulonephritis, which is characterized by the accumulation of dense deposits in the glomerular basement membrane. Patients typically present with symptoms such as hematuria, proteinuria, and potential nephrotic syndrome, which may include edema and hypoalbuminemia. Renal biopsy findings often reveal a characteristic pattern of glomerular changes, including mesangial proliferation and the presence of dense deposits. Management of this condition typically involves nephrology consultation, where treatment may include corticosteroids, immunosuppressive agents, and supportive care to manage symptoms and prevent progression to end-stage renal disease. Regular monitoring of renal function and urinalysis is essential for assessing disease activity and guiding treatment decisions.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Requires understanding of specific renal pathologies.
  • Involves differentiation from other types of hematuria.
  • Management may involve multiple specialties (nephrology, urology).
  • Documentation must be precise to capture the recurrent nature of hematuria.

Audit Risk Factors

  • Inadequate documentation of recurrent hematuria.
  • Failure to document the specific type of glomerulonephritis.
  • Lack of clarity on the relationship between hematuria and dense deposit disease.
  • Insufficient follow-up documentation on management and outcomes.

Specialty Focus

Medical Specialties

Nephrology

Documentation Requirements

Detailed clinical notes on hematuria episodes, renal function tests, and biopsy results.

Common Clinical Scenarios

Patients presenting with unexplained hematuria, proteinuria, or nephrotic syndrome.

Billing Considerations

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

Urology

Documentation Requirements

Comprehensive assessment of urinary tract, including imaging and cystoscopy findings.

Common Clinical Scenarios

Evaluation of hematuria with potential urological causes.

Billing Considerations

Document any interventions or procedures performed to rule out urological pathology.

Coding Guidelines

Inclusion Criteria

Use N02.6 When
  • According to ICD
  • 10 coding guidelines, N02
  • 6 should be used when there is documented recurrent and persistent hematuria specifically linked to dense deposit disease
  • It is essential to ensure that the diagnosis is confirmed through appropriate clinical evaluation and testing

Exclusion Criteria
