The code is not specific and is NOT valid for the year 2025 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.

  • Use R31.0 for Gross hematuria - BILLABLE CODE

  • Use R31.1 for Benign essential microscopic hematuria - BILLABLE CODE

  • R31.2 for Other microscopic hematuria - NON-BILLABLE CODE

  • Use R31.21 for Asymptomatic microscopic hematuria - BILLABLE CODE

  • Use R31.29 for Other microscopic hematuria - BILLABLE CODE

  • Use R31.9 for Hematuria, unspecified - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • hematuria included with underlying conditions, such as:
  • acute cystitis with hematuria N30.01
  • recurrent and persistent hematuria in glomerular diseases N02

Patient Education


Urine and Urination

Your kidneys make urine by filtering wastes and extra water from your blood. The waste is called urea. Your blood carries it to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to urinate. It swells into a round shape when it is full and gets smaller when empty. If your urinary system is healthy, your bladder can hold up to 16 ounces (2 cups) of urine comfortably for 2 to 5 hours.

You may have problems with urination if you have:

  • Kidney failure
  • Urinary tract infections
  • An enlarged prostate
  • Bladder control problems like incontinence, overactive bladder, or interstitial cystitis
  • A blockage that prevents you from emptying your bladder

Some conditions may also cause you to have blood or protein in your urine. If you have a urinary problem, see your health care provider. Urinalysis and other urine tests can help to diagnose the problem. Treatment depends on the cause.
