N04.2
N04.2 — Nephrotic syndrome with diffuse membranous glomerulonephritis
Non-billable headerICD-10-CM
N04.2 is a non-billable header ICD-10-CM code for nephrotic syndrome with diffuse membranous glomerulonephritis. It cannot be billed on its own: choose one of the more specific child codes below.
Other codes that can never be billed with N04.2
These codes carry an Excludes1 note pointing at N04.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N04.2 alone.
Risk adjustment
N04.2 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 N04.2
4 child codes. Green means billable.
