N06.2Isolated proteinuria with diffuse membranous glomerulonephritis

N06.2 is the ICD-10-CM diagnosis code for isolated proteinuria with diffuse membranous glomerulonephritis. It belongs to category N06 (isolated proteinuria with specified morphological lesion), 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 N06 (isolated proteinuria with specified morphological lesion), N06.2 is specifically for isolated proteinuria with diffuse membranous glomerulonephritis. Related codes cover minor glomerular abnormality (N06.0), focal and segmental glomerular lesions (N06.1), diffuse mesangial proliferative glomerulonephritis (N06.3), diffuse endocapillary proliferative glomerulonephritis (N06.4), diffuse mesangiocapillary glomerulonephritis (N06.5), dense deposit disease (N06.6), diffuse crescentic glomerulonephritis (N06.7), other morphologic lesion (N06.8) and 2 more.

To report this condition, pick the subcode that matches the documentation: N06.20 (unspecified), N06.21 (proteinuria), N06.22 (proteinuria) and N06.29 (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 583.1 (nephritis and nephropathy, not specified as acute or chronic, with lesion of membranous glomerulonephritis).
