N05

Unspecified nephritic syndrome

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 11 more specific codes instead:

  • N05.0 Unspecified nephritic syndrome with minor glomerular abnormality
  • N05.1 Unspecified nephritic syndrome with focal and segmental glomerular lesions
  • N05.2 Unspecified nephritic syndrome with diffuse membranous glomerulonephritis
  • N05.3 Unspecified nephritic syndrome with diffuse mesangial proliferative glomerulonephritis
  • N05.4 Unspecified nephritic syndrome with diffuse endocapillary proliferative glomerulonephritis
  • N05.5 Unspecified nephritic syndrome with diffuse mesangiocapillary glomerulonephritis
  • N05.6 Unspecified nephritic syndrome with dense deposit disease
  • N05.7 Unspecified nephritic syndrome with diffuse crescentic glomerulonephritis
  • N05.8 Unspecified nephritic syndrome with other morphologic changes
  • N05.9 Unspecified nephritic syndrome with unspecified morphologic changes
  • N05.A Unspecified nephritic syndrome with C3 glomerulonephritis

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

How CDC's index refers to this code

Wording from the official alphabetic index. Much of it appears nowhere in the code description, which is why a search for the everyday phrase so often finds nothing.
