N06.2 — Isolated proteinuria with diffuse membranous glomerulonephritis
N06.2 is a non-billable header ICD-10-CM code for isolated proteinuria with diffuse membranous glomerulonephritis. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 inherited from the categories above N06.2
These are not written on N06.2, but they bind it: a note on a category applies to every code beneath it. Billing N06.2 with anything listed here is a denial.
Other codes that can never be billed with N06.2
These codes carry an Excludes1 note pointing at N06.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N06.2 alone.
- R80.0Isolated proteinuria
Risk adjustment
N06.2 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 history
N06.2 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Questions about N06.2
- Is N06.2 a billable ICD-10-CM code?
- No. N06.2 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does N06.2 sit in the tabular list?
- Diseases of the genitourinary system (N00-N99), in the block Glomerular diseases (N00-N08).
- What cannot be coded together with N06.2?
- N06.2 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above N06.2 (N06) and apply to it just the same.
