Acute glomerulonephritis with lesion of rapidly progressive glomerulonephritis

This code signifies an acute inflammation of the kidney's glomeruli, specifically characterized by the presence of a rapidly progressive form of glomerulonephritis. This condition involves severe and swift deterioration of kidney function, often associated with crescent formation in the glomeruli.

Apply this code when documentation clearly indicates a diagnosis of acute glomerulonephritis with histological evidence or strong clinical suspicion of rapidly progressive features. This is typically supported by biopsy results showing crescentic changes, rapid decline in GFR, and clinical signs of severe renal impairment.

• Ensure documentation explicitly links acute glomerulonephritis with "rapidly progressive" features or crescentic glomerulonephritis.
• Differentiate from other forms of acute glomerulonephritis that are not rapidly progressive.
• Consider sequencing with codes for underlying systemic diseases if applicable, such as vasculitis or lupus nephritis, as the rapidly progressive glomerulonephritis may be a manifestation.
