Certain infectious and parasitic diseases

Glomerular diseases
(N00-N08)
Use additional code, if desired, to identify external cause (Chapter XX) or presence of
renal failure (N17-N19).
Excludes: hypertensive renal disease ( I12.- )
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 abnormality
Minimal change lesion
.1 Focal and segmental glomerular lesions
Focal and segmental:
· hyalinosis
· 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
N00
Acute nephritic syndrome
[See before N00 for subdivisions ]
Includes: acute:
· glomerular disease
· glomerulonephritis
· nephritis
· renal disease NOS
Excludes: acute infectious tubulo-interstitial nephritis ( N10 )
nephritic syndrome NOS ( N05.- )
