Other isolated protein with diffuse membranous glomrlneph

This code signifies a kidney disorder characterized by the presence of protein in the urine (proteinuria) without other significant kidney abnormalities, specifically due to diffuse membranous glomerulonephritis. This condition involves thickening of the glomerular basement membrane, impairing the kidney's filtering function.

Use this code when documentation explicitly states isolated proteinuria caused by diffuse membranous glomerulonephritis. This diagnosis is typically confirmed by renal biopsy findings. It should be applied when the proteinuria is the primary or sole significant renal manifestation.

• Ensure the documentation specifies "diffuse membranous glomerulonephritis" as the underlying cause of the proteinuria.
• Distinguish from other forms of glomerulonephritis or proteinuria not explicitly linked to diffuse membranous changes.
• Do not use if other significant renal pathologies are present; consider more specific codes for those conditions.
