2025 ICD-10-CM code N02

Recurrent and persistent hematuria.

Follow the official ICD-10-CM coding guidelines for selecting the most specific code based on the available clinical documentation. When possible, always code the underlying cause of the hematuria rather than just the symptom itself. Always maintain accurate documentation.

Modifiers are not typically applied to ICD-10-CM codes. Modifiers are used with procedure codes such as CPT codes.

Medical necessity for coding N02 is established when recurrent or persistent hematuria is present and requires further evaluation to rule out or identify underlying renal or urinary tract pathology.The physician must document the clinical findings supporting the persistent nature of the hematuria and any investigations performed to determine the underlying cause.

The clinical responsibility for this code lies with a nephrologist or urologist, who would order further investigations to determine the underlying cause of hematuria, such as urinalysis, imaging studies (ultrasound, CT scan), and potentially a kidney biopsy.

IMPORTANT:Consider additional codes for specific underlying glomerular diseases or other causes of hematuria (e.g., IgA nephropathy, N02.B).Also code any associated kidney failure (N17-N19). Excludes acute cystitis with hematuria (N30.01), hematuria NOS (R31.9), and hematuria not associated with specified morphologic lesions (R31.-).

In simple words: This code means that blood is repeatedly or constantly found in the urine.It's a sign that something may be wrong with the kidneys or urinary tract, and more tests are needed to figure out the exact problem.

This ICD-10-CM code classifies recurrent and persistent hematuria, which is the presence of blood in the urine that occurs repeatedly or continuously.It's a symptom that can indicate various underlying kidney or urinary tract conditions.Further investigation is necessary to determine the root cause.This code should be used when hematuria is a persistent clinical finding and other specific diagnoses have been ruled out or are unclear.

Example 1: A 45-year-old female patient presents with a history of recurrent macroscopic hematuria (visible blood in the urine) for the past six months.Investigations reveal no specific glomerular disease, and other causes are excluded. Code N02 is used., A 60-year-old male patient with known hypertension and diabetes presents with microscopic hematuria (blood detected only on microscopic examination) detected during routine urinalysis. After a kidney biopsy, diffuse membranous glomerulonephritis is diagnosed.Appropriate additional codes should be used alongside N02., A 20-year-old female patient experiences episodic gross hematuria associated with menstrual cycles for several years.The hematuria resolves between periods.Code N02 may not be the most appropriate code in this scenario, as the hematuria appears to be primarily menstrual-related.Further investigation is required to determine if the hematuria is exclusively menstrual-related, or if another underlying issue is present.

Detailed history of hematuria (frequency, duration, amount, associated symptoms), results of urinalysis, microscopic examination of urine sediment, any imaging studies (ultrasound, CT scan, etc.), and results of any renal biopsies performed to ascertain the underlying cause of the hematuria are crucial for proper coding.

** This code should not be used to code hematuria solely due to menstruation or trauma.Always document the appropriate context and ensure there is supporting medical evidence to show the nature of the hematuria is recurrent and persistent.Careful clinical investigation is required to clarify the underlying cause.
