About N02.B3

N02.B3 is the ICD-10-CM diagnosis code for recurrent and persistent immunoglobulin A nephropathy with diffuse membranoproliferative glomerulonephritis. It belongs to category N02 (recurrent and persistent hematuria), block N00-N08 (glomerular diseases) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within N02.B (recurrent and persistent immunoglobulin A nephropathy), N02.B3 is specifically for recurrent and persistent immunoglobulin A nephropathy with diffuse membranoproliferative glomerulonephritis. Related codes cover with glomerular lesion (N02.B1), with focal and segmental glomerular lesion (N02.B2), with diffuse membranous glomerulonephritis (N02.B4), with diffuse mesangial proliferative glomerulonephritis (N02.B5), with diffuse mesangiocapillary glomerulonephritis (N02.B6) and other recurrent and persistent immunoglobulin A nephropathy (N02.B9).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It was added in FY2024, effective October 1, 2023.
