Code Description

ICD-10 N03.7 is a billable code used to indicate a diagnosis of chronic nephritic syndrome with diffuse crescentic glomerulonephritis.

Key Diagnostic Point:

Chronic nephritic syndrome with diffuse crescentic glomerulonephritis is characterized by the presence of significant renal impairment due to the inflammation of the glomeruli, leading to the formation of crescents in the Bowman’s space. This condition typically presents with symptoms such as hematuria, proteinuria, and hypertension. Patients may also experience edema and renal insufficiency. The crescentic formation indicates a severe form of glomerulonephritis, often associated with rapidly progressive renal failure. Diagnosis is confirmed through renal biopsy, which reveals crescentic changes along with inflammatory cell infiltration. Management involves immunosuppressive therapy, including corticosteroids and cytotoxic agents, to reduce inflammation and prevent further renal damage. Close monitoring of renal function and regular follow-up are essential to manage complications and adjust treatment as necessary.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Requires detailed clinical documentation to support diagnosis.
  • Differentiation from other types of nephritis and glomerulonephritis.
  • Need for renal biopsy results to confirm diagnosis.
  • Management may involve multiple specialties, complicating coding.

Audit Risk Factors

  • Inadequate documentation of renal biopsy findings.
  • Failure to document the severity of symptoms.
  • Misclassification of nephritic syndrome types.
  • Lack of follow-up documentation on treatment response.
