Nephrotic 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.
- FY2007 Added to the draft code set draft Nephrotic syndrome with unspecified morphologic changes
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 N04 Nephrotic syndrome
Includes
- congenital nephrotic syndrome
- lipoid nephrosis
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).
