Modifiers
The following fourth-character subdivisions classify morphological changes and are for use with categories N00, N01, N02, N03, N04, N05, N06, N07. Subdivisions .0-.8 should not normally be used unless these have been specifically identified (e.g. by renal biopsy or autopsy). The three-character categories relate to clinical syndromes.
- .0 Minor glomerular abnormality
- Minimal change lesion
- .1 Focal and segmental glomerular lesions
- Focal and segmental: hyalinosis
- Focal and segmental: sclerosis
- Focal glomerulonephritis
- .2 Diffuse membranous glomerulonephritis
- .3 Diffuse mesangial proliferative glomerulonephritis
- .4 Diffuse endocapillary proliferative glomerulonephritis
- .5 Diffuse mesangiocapillary glomerulonephritis
- Membranoproliferative glomerulonephritis, types 1 and 3, or NOS
- .6 Dense deposit disease
- Membranoproliferative glomerulonephritis, type 2
- .7 Diffuse crescentic glomerulonephritis
- Extracapillary glomerulonephritis
- .8 Other
- Proliferative glomerulonephritis NOS
- .9 Unspecified
