Other nephrotic syndrome with diffuse membranous glomrlneph

This code signifies a specific type of nephrotic syndrome characterized by widespread thickening of the glomerular basement membrane due to immune complex deposition. It indicates that the underlying cause is diffuse membranous glomerulonephritis, but the presentation does not fit other more specific categories of nephrotic syndrome.

Use this code when documentation confirms a diagnosis of nephrotic syndrome and specifies diffuse membranous glomerulonephritis as the etiology, without further detail that would allow for a more precise subclassification. Supporting documentation should include renal biopsy findings consistent with diffuse membranous glomerulonephritis and clinical signs of nephrotic syndrome (e.g., proteinuria, hypoalbuminemia, edema).

• Ensure the documentation explicitly states "diffuse membranous glomerulonephritis" as the cause of the nephrotic syndrome.
• Differentiate from other specified types of nephrotic syndrome (e.g., N04.0, N04.1) which have distinct pathological findings.
• Code any associated chronic kidney disease (CKD) separately, typically as a secondary diagnosis.
