Code Description

ICD-10 N06.2 is a billable code used to indicate a diagnosis of isolated proteinuria with diffuse membranous glomerulonephritis.

Key Diagnostic Point:

Isolated proteinuria with diffuse membranous glomerulonephritis is characterized by the presence of excess protein in the urine without significant hematuria or other renal dysfunction. This condition is often associated with diffuse membranous glomerulonephritis, which is a type of kidney disease that affects the glomeruli, the filtering units of the kidneys. In this disorder, the glomerular basement membrane becomes thickened due to the deposition of immune complexes, leading to increased permeability and protein leakage into the urine. Patients may present with symptoms such as edema, hypertension, and foamy urine, although many may be asymptomatic. Diagnosis typically involves urinalysis, serum creatinine levels, and kidney biopsy to confirm the presence of membranous changes. Genetic factors may play a role in the development of this condition, particularly in hereditary nephropathies. Understanding the underlying causes and potential genetic predispositions is crucial for effective management and treatment.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between isolated proteinuria and other forms of proteinuria.
  • Understanding the relationship between membranous glomerulonephritis and other glomerular disorders.
  • Identifying hereditary nephropathies that may present similarly.
  • Navigating the documentation requirements for genetic testing.

Audit Risk Factors

  • Inadequate documentation of the type and cause of proteinuria.
  • Failure to document associated symptoms or comorbidities.
  • Misclassification of the type of glomerulonephritis.
  • Lack of genetic testing documentation when applicable.
