N04.B
N04.B — Nephrotic syndrome with immune complex membranoproliferative glomerulonephritis (IC-MPGN)
Non-billable headerICD-10-CM
N04.B is a non-billable header ICD-10-CM code for nephrotic syndrome with immune complex membranoproliferative glomerulonephritis (ic-mpgn). It cannot be billed on its own: choose one of the more specific child codes below.
Risk adjustment
N04.B does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code to one of these instead N04.B
2 child codes. Green means billable.
