N02.B5
BillableRecurrent and persistent immunoglobulin A nephropathy with diffuse mesangial proliferative glomerulonephritis
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Repeated episodes of blood in the urine from IgA nephropathy with widespread proliferation of mesangial cells, the supporting cells in the kidney filters.
Coding Tips
- •B5 indicates diffuse mesangial proliferative pattern; ensure biopsy confirms increased mesangial cellularity
- •This pattern is common in IgA nephropathy and indicates moderate disease severity
