About N07.0

N07.0 is the ICD-10-CM diagnosis code for hereditary nephropathy, not elsewhere classified with minor glomerular abnormality. It belongs to category N07 (hereditary nephropathy, not elsewhere classified), block N00-N08 (glomerular diseases) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within N07 (hereditary nephropathy, not elsewhere classified), N07.0 is specifically for hereditary nephropathy, not elsewhere classified with minor glomerular abnormality. Related codes cover with focal and segmental glomerular lesions (N07.1), with diffuse membranous glomerulonephritis (N07.2), with diffuse mesangial proliferative glomerulonephritis (N07.3), with diffuse endocapillary proliferative glomerulonephritis (N07.4), with diffuse mesangiocapillary glomerulonephritis (N07.5), with dense deposit disease (N07.6), with diffuse crescentic glomerulonephritis (N07.7), with other morphologic lesions (N07.8) and 3 more.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

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

Before ICD-10, this condition was coded in ICD-9-CM as 583.89 (nephritis and nephropathy, not specified as acute or chronic, with other specified pathological lesion in kidney).
