Acute nephritic syndrome with unspecified morphologic changes
ValidICD-10-CM diagnosis code.
Valid for claims with a date of service in the current code year.
What has happened to this code
Every change the publisher made, from 2007 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.

Official coding rules
Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
Inherited from N00 Acute nephritic syndrome
Excludes1 - never coded here
- acute tubulo-interstitial nephritis (N10)
- nephritic syndrome NOS (N05.-)
Includes
- acute glomerular disease
- acute glomerulonephritis
- acute nephritis
Inherited from the N00-N08 section Glomerular diseases (N00-N08)
Excludes1 - never coded here
- hypertensive chronic kidney disease (I12.-)
Code also
- any associated kidney failure (N17-N19).
