Nephrotic syndrome with lesion of minimal change glomerulonephritis

This code identifies a specific type of nephrotic syndrome characterized by minimal change glomerulonephritis (MCGN). Nephrotic syndrome is a kidney disorder causing the body to excrete too much protein in the urine, leading to symptoms like severe edema, hypoalbuminemia, hyperlipidemia, and lipiduria. MCGN is diagnosed via renal biopsy, showing normal glomeruli under light microscopy but effacement of podocyte foot processes on electron microscopy.

Use this code when documentation explicitly states a diagnosis of nephrotic syndrome and specifies the underlying renal pathology as minimal change glomerulonephritis. This is typically confirmed by a renal biopsy report. It is appropriate for both initial diagnosis and subsequent encounters where the condition is being managed.

• Ensure the documentation clearly links the nephrotic syndrome to minimal change glomerulonephritis; avoid using this code if the specific lesion is not identified.
• Do not confuse this with other forms of glomerulonephritis or nephrotic syndrome where the underlying pathology is different.
• Always review the pathology report for definitive diagnosis of minimal change glomerulonephritis.
