Note
- See note under chapter heading (N00-N08) for fourth character subdivisions
- The following fourth-character subdivisions classify morphological changes and are for use with categories N00 - 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 abnormalityMinimal change lesion.1 Focal and segmental glomerular lesionsGlomerulonephritis, Hyalinosis, Sclerosis — focal and segmental.2 Diffuse membranous glomerulonephritis.3 Diffuse mesangial proliferative glomerulonephritis.4 Diffuse endocapillary proliferative glomerulonephritis.5 Diffuse mesangiocapillary glomerulonephritisMembranoproliferative glomerulonephritis, types 1 and 3, or NOS.6 Dense deposit diseaseMembranoproliferative glomerulonephritis, type 2.7 Diffuse crescentic glomerulonephritisExtracapillary glomerulonephritis.8 OtherProliferative glomerulonephritis NOS.9 UnspecifiedFrom N00-N08 Glomerular diseases
