Hematuria ICD-10-CM Codes

What are Hematuria ICD-10-CM Codes?

It's important to note that hematuria ICD codes typically indicate a specific complication associated with hematuria, or hematuria itself can be a complication of another underlying issue. To accurately represent your patient's condition, consider selecting the code that best corresponds to their situation. Here are six examples:

R31 Hematuria is the general code used to indicate the presence of blood in the urine when no further details are specified. It serves as a broad category for hematuria and is used when the type or cause of hematuria has not been determined or documented. This code is also used for persistent hematuria linked to various abnormal findings. This is not valid for billing and reimbursement, but specific codes under this category are.

Here are the following ICD-10 codes for hematuria:

• R31.0 Gross hematuria: This code is used when blood is visibly present in the urine. Gross hematuria means that the blood can be seen with the naked eye, often causing the urine to appear pink, red, or cola-colored. It can be a sign of various underlying conditions such as urinary tract infections, kidney stones, trauma, or malignancies. Gross hematuria may accompany diffuse mesangial proliferative glomerulonephritis or acute cystitis with hematuria in more severe urinary tract disorders.
• R31.1 Benign essential microscopic hematuria: This code applies to abnormal clinical findings where microscopic amounts of blood are detected in the urine through laboratory testing, but no underlying pathological cause is identified. It is considered “benign” because it does not indicate a serious disease and often requires monitoring rather than aggressive treatment.
• R31.21 Asymptomatic microscopic hematuria: This code is designated for patients who have microscopic hematuria detected incidentally and do not experience any symptoms related to it. It emphasizes that the blood in the urine is discovered during routine testing or evaluation for other conditions without any associated clinical signs.
• R31.29 Other microscopic hematuria: This category includes other specified forms of microscopic hematuria that do not fit into the previously mentioned subcategories. It is used when the microscopic blood in the urine has a known but less common cause or presentation, such as glomerular diseases or abnormal results from kidney function tests.
• R31.9 Hematuria, unspecified: This code applies when hematuria is documented but there is insufficient information to classify it as gross or microscopic, or when the type of hematuria is not clearly identified in the medical record. It is a catch-all code used in the absence of more specific details and is categorized under unspecified symptoms of the genitourinary system.

Are these hematuria ICD codes billable?

All the codes above are recognized as billable/specific ICD-10-CM codes, meaning they can be used for medical billing and insurance reimbursement.

Clinical information

• Hematuria is the medical term for the presence of blood in the urine. 
• Healthcare professionals also employ other terminology to distinguish between various types of hematuria. 
•  Microscopic indicates the presence of blood in the urine that is not visible to the naked eye and requires a microscope for detection. 
• Another term, "dipstick," refers to a urine test strip undergoing oxidation, resulting in a color change.
• It is important to note that a color change on the dipstick does not necessarily indicate the presence of blood in the urine. This type of hematuria has a higher likelihood of producing false positives.

Synonyms include

• Hematuria
• Haematuria
• Blood in the urine
• Erythrocyturia
• Haematocyturia / Hematocyturia
• Presence of blood cells in urine)
• Gross hematuria
• Microscopic hematuria
• Asymptomatic microscopic hematuria (microscopic hematuria without symptoms)
• Visible hematuria
• Overt hematuria
• Tea-colored urine

• N30.01 – Acute cystitis with hematuria:
• N02.- – Recurrent and persistent hematuria
• N20.0 – Calculus of kidney (kidney stones)
• C67.9 – Malignant neoplasm of bladder, unspecified
• N10 – Acute pyelonephritis
• N39.0 – Urinary tract infection, site not specified
