N07Hereditary nephropathy, not elsewhere classified

N07 is the ICD-10-CM diagnosis code for hereditary nephropathy, not elsewhere classified. It belongs to 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 12 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: N07.0 (with minor glomerular abnormality), N07.1 (with focal and segmental glomerular lesions), N07.2 (with diffuse membranous glomerulonephritis), N07.3 (with diffuse mesangial proliferative glomerulonephritis), N07.4 (with diffuse endocapillary proliferative glomerulonephritis), N07.5 (with diffuse mesangiocapillary glomerulonephritis), N07.6 (with dense deposit disease), N07.7 (with diffuse crescentic glomerulonephritis) and 4 more.

The conditions in its Excludes2 note aren't part of N07, but may be coded alongside it if the patient has both: Alport's syndrome (Q87.81-), hereditary amyloid nephropathy (E85.-), nail patella syndrome (Q87.2) and non-neuropathic heredofamilial amyloidosis (E85.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
