Acute glomerulonephritis with lesion of proliferative glomerulonephritis

This code signifies an acute inflammation of the kidney's glomeruli, specifically characterized by the presence of proliferative changes within the glomerular tissue. This condition often results in impaired kidney function due to damage to the filtering units.

Assign this code when documentation clearly indicates a diagnosis of acute glomerulonephritis and specifies a proliferative lesion identified through renal biopsy or other diagnostic studies. It is appropriate for initial episodes of this specific type of acute glomerular disease.

• Ensure the documentation explicitly states "proliferative glomerulonephritis" in an acute setting.
• Distinguish from chronic glomerulonephritis or other specific types of glomerulonephritis (e.g., membranous, focal segmental).
• Code any associated underlying systemic diseases (e.g., streptococcal infection) as additional diagnoses.
