N04.2Nephrotic syndrome with diffuse membranous glomerulonephritis

N04.2 is the ICD-10-CM diagnosis code for nephrotic syndrome with diffuse membranous glomerulonephritis. It belongs to category N04 (nephrotic syndrome), block N00-N08 (glomerular diseases) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within N04 (nephrotic syndrome), N04.2 is specifically for nephrotic syndrome with diffuse membranous glomerulonephritis. Related codes cover with minor glomerular abnormality (N04.0), with focal and segmental glomerular lesions (N04.1), with diffuse mesangial proliferative glomerulonephritis (N04.3), with diffuse endocapillary proliferative glomerulonephritis (N04.4), with diffuse mesangiocapillary glomerulonephritis (N04.5), with dense deposit disease (N04.6), with diffuse crescentic glomerulonephritis (N04.7), with other morphologic changes (N04.8) and 3 more.

To report this condition, pick the subcode that matches the documentation: N04.20 (unspecified), N04.21 (syndrome), N04.22 (syndrome) and N04.29 (glomerulonephritis).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2024 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 581.1 (nephrotic syndrome with lesion of membranous glomerulonephritis).
