Rapidly progr nephritic syndrome w minor glomerular abnlt

This code signifies a severe and rapidly worsening form of kidney inflammation (nephritic syndrome) characterized by the sudden onset of hematuria, proteinuria, and declining renal function, where kidney biopsy reveals only minor changes to the glomeruli. It indicates a swift progression towards end-stage renal disease if untreated.

Apply this code when documentation explicitly states "rapidly progressive nephritic syndrome" and a renal biopsy report confirms "minor glomerular abnormality." This diagnosis is typically made after acute kidney injury with evidence of glomerular disease and a rapid decline in GFR over weeks to months.

• Ensure the documentation clearly distinguishes "rapidly progressive" from other forms of nephritic syndrome.
• Verify the biopsy findings specifically state "minor glomerular abnormality" to support this precise code.
• Do not use this code if the biopsy reveals significant glomerular lesions, such as crescentic glomerulonephritis, even if the progression is rapid.
