What This Code Means
N02.A is the ICD-10-CM diagnosis code for recurrent and persistent hematuria with c3 glomerulonephritis. Repeated episodes of blood in the urine caused by a specific type of kidney inflammation called C3 glomerulonephritis, where complement protein C3 accumulates in the kidney filters. N02.A sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering glomerular diseases (n00-n08).
N02.A 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.
This code requires documentation of both recurrent hematuria and C3 glomerulonephritis diagnosis.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for N02.A sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This code requires documentation of both recurrent hematuria and C3 glomerulonephritis diagnosis
- •Ensure biopsy results or clinical findings confirm C3 glomerulonephritis rather than other glomerulonephritis types
Excludes 1, Do NOT code together
- Recurrent and persistent hematuria (with C3 glomerulopathy) with dense deposit disease (N02.6)
