Billable

Recurrent and persistent immunoglobulin A nephropathy with glomerular lesion

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 due to IgA nephropathy, an autoimmune kidney disease where immunoglobulin A antibodies damage the kidney filters.

Coding Tips

  • •Confirm kidney biopsy showing IgA deposits on immunofluorescence microscopy
  • •B1 indicates minimal glomerular changes; document the specific pathological findings
