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

Their own Excludes1 notes name this code, so the conflict is not listed above.

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