N04.7Nephrotic syndrome with diffuse crescentic glomerulonephritis

N04.7 is the ICD-10-CM diagnosis code for nephrotic syndrome with diffuse crescentic glomerulonephritis. It belongs to category N04 (nephrotic syndrome), 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 N04 (nephrotic syndrome), N04.7 is specifically for nephrotic syndrome with diffuse crescentic glomerulonephritis. Related codes cover with minor glomerular abnormality (N04.0), with focal and segmental glomerular lesions (N04.1), with diffuse membranous glomerulonephritis (N04.2), with diffuse mesangial proliferative glomerulonephritis (N04.3), with diffuse endocapillary proliferative glomerulonephritis (N04.4), with diffuse mesangiocapillary glomerulonephritis (N04.5), with dense deposit disease (N04.6), with other morphologic changes (N04.8) and 3 more.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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 581.89 (nephrotic syndrome with other specified pathological lesion in kidney).
