Unspecified abnormal finding in cerebrospinal fluid
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 the R83-R89 section Abnormal findings on examination of other body fluids, substances and tissues, without diagnosis (R83-R89)
Excludes1 - never coded here
- abnormal findings on antenatal screening of mother (O28.-)
- diagnostic abnormal findings classified elsewhere - see Alphabetical Index
Excludes2 - not included here
- abnormal findings on examination of blood, without diagnosis (R70-R79)
- abnormal findings on examination of urine, without diagnosis (R80-R82)
- abnormal tumor markers (R97.-)
