Code Description

ICD-10 N03.0 is a billable code used to indicate a diagnosis of chronic nephritic syndrome with minor glomerular abnormality.

Key Diagnostic Point:

Chronic nephritic syndrome with minor glomerular abnormality is characterized by persistent proteinuria, hematuria, and hypertension, often resulting from underlying glomerular diseases. This condition is typically associated with minimal changes in glomerular structure, which may not be evident on standard imaging or light microscopy but can be identified through electron microscopy. Patients may present with symptoms such as edema, fatigue, and decreased urine output. The pathophysiology involves immune-mediated damage to the glomeruli, leading to increased permeability and subsequent protein loss in urine. Diagnosis is often confirmed through renal biopsy, which may reveal minimal glomerular changes, and laboratory tests showing elevated serum creatinine and abnormal urinalysis findings. Management includes controlling blood pressure, reducing proteinuria with ACE inhibitors or ARBs, and addressing any underlying conditions. Regular monitoring of renal function and protein levels is essential to prevent progression to end-stage renal disease.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and severity of symptoms
  • Need for renal biopsy to confirm diagnosis
  • Differentiation from other types of nephritic syndromes
  • Potential for overlapping symptoms with nephrotic syndrome

Audit Risk Factors

  • Inadequate documentation of renal biopsy results
  • Failure to document the presence of proteinuria and hematuria
  • Lack of clarity in distinguishing between nephritic and nephrotic syndromes
  • Insufficient follow-up documentation on treatment efficacy
