Nephrotic syndrome with minor glomerular abnormality

This code identifies a specific type of nephrotic syndrome characterized by significant proteinuria, hypoalbuminemia, edema, and hyperlipidemia, where kidney biopsy reveals only minor changes to the glomeruli under light microscopy. It often presents as minimal change disease, which is the most common cause of nephrotic syndrome in children.

Apply this code when documentation confirms nephrotic syndrome and a renal biopsy report indicates minor glomerular abnormalities, such as minimal change disease. This diagnosis is typically made after excluding other causes of nephrotic syndrome and confirming the characteristic histological findings.

• Ensure documentation explicitly states "minor glomerular abnormality" or "minimal change disease" in the context of nephrotic syndrome.
• Do not use this code if the biopsy shows significant glomerular lesions, such as focal segmental glomerulosclerosis or membranous nephropathy.
• Sequence this code as the primary diagnosis when nephrotic syndrome with minor glomerular abnormality is the reason for the encounter.
