    ICD-10-CM Code For Recurrent And Persistent Hematuria: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group N02 includes diagnoses for recurrent and persistent hematuria of glomerular origin, covering conditions with repeated or ongoing blood in the urine due to underlying glomerular disease. These ICD-10-CM diagnosis codes are used to document clinical scenarios involving chronic or recurrent glomerular bleeding, capturing disease severity, organ involvement, or clinical complexity relevant to this group. Accurate coding within the ICD-10-CM N02 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM N02: Recurrent And Persistent Hematuria Overview

    The diagnoses in this group represent recurrent or persistent bleeding from the urinary tract originating in the glomeruli. They target glomerular diseases affecting the kidneys and presenting with repeated or ongoing hematuria. Accurate coding matters for correct clinical records and can impact reimbursement by reflecting disease complexity.

    When to Use

    Use codes from this group when documentation indicates ongoing or repeated hematuria attributed to glomerular disease rather than transient or isolated bleeding. Assign a specific N02 code when clinical notes describe recurrent or persistent glomerular hematuria with the appropriate laterality or presentation details.

    Typical Clinical Scenarios

    • An adult patient with a history of IgA nephropathy presents to clinic for worsening frothy urine and visible blood intermittently over several months, accompanied by mild flank discomfort and a stable creatinine. Urinalysis confirms persistent hematuria with red blood cell casts and proteinuria on repeat testing, and the nephrologist documents recurrent glomerular bleeding as part of the known glomerular disease; a code from this group is assigned to reflect recurrent and persistent hematuria of glomerular origin. Typical codes: N02.0, N02.1
    • A young adolescent is brought to the emergency department with sudden onset of cola-colored urine and oliguria following an upper respiratory infection; evaluation reveals acute nephritic features with elevated blood pressure and RBC casts, but symptoms persist beyond the acute phase into a recurrent course. Because the hematuria is glomerular in origin and has continued after the initial episode, a code from this group is used to capture recurrent/persistent glomerular hematuria during follow-up and management. Typical codes: N02.2, N02.3
    • An older patient with chronic kidney disease due to diabetic nephropathy is admitted for evaluation of worsening anemia and persistent microscopic hematuria on serial urinalyses without a new urologic source; nephrology documents ongoing glomerular bleeding contributing to monitoring and adjustment of care plans. A diagnosis from this group is recorded to indicate persistent glomerular hematuria as a comorbidity influencing the patient’s CKD management. Typical codes: N02.7, N02.9
