R31 — Hematuria

Non-billable headerICD-10-CM

R31 is a non-billable header ICD-10-CM code for 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.

hematuria included with underlying conditions, such as:
acute cystitis with hematuria (N30.01)
recurrent and persistent hematuria in glomerular diseases (N02.-)

Other codes that can never be billed with R31

These codes carry an Excludes1 note pointing at R31. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R31 alone.

N02Recurrent and persistent hematuria
N42.1Congestion and hemorrhage of prostate

Risk adjustment

R31 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 R31

4 child codes. Green means billable.
