hematuria

Definition of hematuria

hemat-ur--ia - blood in urine (condition of blood in urine); Hematuria refers to blood or red blood cells mixing with urine, with bleeding that can originate anywhere in the urinary system (kidney, ureter, bladder, urethra) and in men also the prostate. Gross hematuria may change urine color and can include clots that may cause pain or obstruct urine flow, while microscopic hematuria often has no symptoms.

Diagnosis Codes:

• R31.0: gross hematuria
  • Explanation: Used when the patient or clinician can see blood in the urine. The urine may appear bright red, pink, or “tea-colored.”
• R31.21: Asymptomatic microscopic hematuria
  • Explanation: Specifically for cases where blood is found during a routine test or screening in a patient who has no other symptoms (like pain or frequency).
• R31.9: hematuria, unspecified
  • Explanation: The default code used when the documentation states “hematuria” but does not specify if it is gross or microscopic.

CPT/HCPCS Code(s) (Common Diagnostic Procedures):

When a patient presents with hematuria, a workup is performed to find the source. These are the most common codes associated with that evaluation:

• 52000 - Cystourethroscopy (separate procedure)
• Explanation: A diagnostic procedure where a scope is inserted into the bladder to look for tumors, stones, or bleeding sites.
  • wRVU: 1.10 (Facility) / 2.06 (Non-Facility)
  • Global Period: 000
• Assistant Payable: No
  • Bundling: Bundled into more extensive procedures (e.g., if a biopsy 52204 is performed, 52000 is not billed).
• 81001 - Urinalysis, automated, with microscopy
• Explanation: Used to confirm the presence of red blood cells (RBCs) and screen for infection (nitrites/leukocytes) as a cause.
  • Global Period: XXX
• 74177 - CT Abdomen and Pelvis with contrast
• Explanation: Often referred to as a “CT Urogram,” this is used to check the kidneys and ureters for stones or masses.
• Global Period: XXX

Etymology of hematuria

Hematuria is built from greek roots: “haima” (blood) + “ouron/-uria” (urine/urination). In word-part terms used in med terminology, it’s essentially hemat-/hem- (blood) + -uria (urine condition).

Note

• Microhematuria / microscopic hematuria: small amounts of blood in urine not visible to the eye.​
• Gross hematuria: visible blood/discoloration in urine.
• Red urine ≠ hematuria (look-alikes): discoloration can also come from hemoglobin, myoglobin, porphyrins, some drugs, or foods (e.g., beets), so confirmation is typically by urinalysis/microscopy.
