N02.4
BillableRecurrent and persistent hematuria with diffuse endocapillary proliferative glomerulonephritis
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is N02.4 an HCC code?
No. N02.4 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
N02.4 is the ICD-10-CM diagnosis code for recurrent and persistent hematuria with diffuse endocapillary proliferative glomerulonephritis. Persistent blood in the urine caused by widespread inflammation and cell growth in the inner lining of the kidney's blood vessels. N02.4 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering glomerular diseases (n00-n08).
N02.4 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Ensure the endocapillary proliferation is clearly documented in the renal biopsy findings.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for N02.4 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Ensure the endocapillary proliferation is clearly documented in the renal biopsy findings.
- •Differentiate from extracapillary proliferation, which would indicate a different glomerular disease pattern.
