Is N06 a billable ICD-10-CM code?

No. N06 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does N06 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?

N06 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

N06

N06 — Isolated proteinuria with specified morphological lesion

Non-billable headerICD-10-CM

N06 is a non-billable header ICD-10-CM code for isolated proteinuria with specified morphological lesion. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

Proteinuria not associated with specific morphologic lesions (R80.0)

Other codes that can never be billed with N06

These codes carry an Excludes1 note pointing at N06. 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 alone.

N06.5Isolated proteinuria with diffuse mesangiocapillary glomerulonephritis
N06.AIsolated proteinuria with C3 glomerulonephritis
R80.0Isolated proteinuria

Risk adjustment

N06 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 N06

11 child codes. Green means billable.
