N02.A ICD-10-CM Code: Recurrent and persistent hematuria with C3 glomerulonephritis
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
Inpatient Payment Groups (MS-DRG)
MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0, Appendix B.
- MS-DRG 698 — OTHER KIDNEY AND URINARY TRACT DIAGNOSES WITH MCC (MDC 11)
- MS-DRG 699 — OTHER KIDNEY AND URINARY TRACT DIAGNOSES WITH CC (MDC 11)
- MS-DRG 700 — OTHER KIDNEY AND URINARY TRACT DIAGNOSES WITHOUT CC/MCC (MDC 11)
A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Potential MS-DRG Relationships (FY2026)
CC — Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 131 clinically related codes on its CMS exclusion list.
Named in the grouper logic of 3 MS-DRGs: DRG 698 (MDC 11), DRG 699 (MDC 11), DRG 700 (MDC 11).
From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.

Same clinical process (MS-DRG)
Acts as CC — raises the severity of other admissions. CMS groups these diagnoses into one MS-DRG principal-diagnosis exclusion process — a CC/MCC on this list never raises severity when the principal diagnosis is also on it.
