Code Description

ICD-10 N02.4 is a billable code used to indicate a diagnosis of recurrent and persistent hematuria with diffuse endocapillary proliferative glomerulonephritis.

Key Diagnostic Point:

N02.4 refers to a condition characterized by recurrent and persistent hematuria, which is the presence of blood in the urine, associated with diffuse endocapillary proliferative glomerulonephritis (GN). This type of GN is marked by an increase in the number of cells within the capillary loops of the glomeruli, leading to inflammation and damage. Patients typically present with symptoms such as hematuria, proteinuria, and possible edema. The condition can be secondary to infections, autoimmune diseases, or other underlying health issues. Diagnosis often involves renal biopsy, which may reveal hypercellularity, mesangial proliferation, and immune complex deposition. Management may include corticosteroids, immunosuppressive agents, and supportive care to control symptoms and prevent progression to chronic kidney disease. Regular monitoring of renal function and urine analysis is essential for assessing disease activity and treatment efficacy.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Requires understanding of nephrology terminology and conditions.
  • Involves differentiating between various types of glomerulonephritis.
  • Documentation must clearly indicate the presence of hematuria and its persistence.
  • Requires knowledge of renal biopsy findings and their implications.

Audit Risk Factors

  • Inadequate documentation of hematuria persistence.
  • Failure to document renal biopsy findings.
  • Misclassification of glomerulonephritis type.
  • Lack of clarity in treatment plans.
