Is N02 a billable ICD-10-CM code?

No. N02 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does N02 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 N02?

N02 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

N02

N02 — Recurrent and persistent hematuria

Non-billable headerICD-10-CM

N02 is a non-billable header ICD-10-CM code for recurrent and persistent hematuria. 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.

acute cystitis with hematuria (N30.01)
hematuria NOS (R31.9)
hematuria not associated with specified morphologic lesions (R31.-)

Other codes that can never be billed with N02

These codes carry an Excludes1 note pointing at N02. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N02 alone.

N02.5Recurrent and persistent hematuria with diffuse mesangiocapillary glomerulonephritis
N02.ARecurrent and persistent hematuria with C3 glomerulonephritis
R31Hematuria

Risk adjustment

N02 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 N02

12 child codes. Green means billable.
