Acute nephritic syndrome with minor glomerular abnormality

This code signifies a sudden onset of kidney inflammation characterized by hematuria, proteinuria, and often hypertension and edema, specifically when the underlying kidney tissue damage is minimal and primarily affects the glomeruli. It represents an acute inflammatory process within the kidney's filtering units.

Apply this code when documentation explicitly states "acute nephritic syndrome" and specifies "minor glomerular abnormality" or similar findings on renal biopsy. This diagnosis is typically supported by clinical signs and symptoms of acute nephritis, coupled with histological evidence of minimal glomerular changes.

• Differentiate from chronic nephritic syndromes (N03.-) which involve persistent or long-standing inflammation.
• Ensure documentation specifies "acute" and "minor glomerular abnormality" to avoid miscoding to other forms of acute glomerulonephritis.
• Review pathology reports carefully for the precise nature and extent of glomerular involvement.
