Nep syn w idio imm cmplx membr prolif glomrlneph (IC-MPGN)

This code signifies a specific type of nephrotic syndrome characterized by significant proteinuria, hypoalbuminemia, edema, and hyperlipidemia, occurring in the context of idiopathic immune complex membranoproliferative glomerulonephritis (IC-MPGN). IC-MPGN is a kidney disease where immune complexes deposit in the glomeruli, leading to inflammation and damage.

Use this code when documentation clearly indicates a diagnosis of nephrotic syndrome and specifies the underlying cause as idiopathic immune complex membranoproliferative glomerulonephritis. This typically applies to patients undergoing diagnostic workup, treatment, or long-term management for this particular renal condition. Supporting documentation would include pathology reports confirming IC-MPGN and clinical findings consistent with nephrotic syndrome.

• Ensure the documentation explicitly states "idiopathic immune complex" to differentiate from other forms of MPGN.
• Do not use if the cause of the membranoproliferative glomerulonephritis is secondary to another condition (e.g., hepatitis C, autoimmune disease).
• Code any associated complications of nephrotic syndrome, such as acute kidney injury or thrombosis, separately.
