Abnormal findings in cerebrospinal fluid

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 9 more specific codes instead:

R83.0 Abnormal level of enzymes in cerebrospinal fluid
R83.1 Abnormal level of hormones in cerebrospinal fluid
R83.2 Abnormal level of other drugs, medicaments and biological substances in cerebrospinal fluid
R83.3 Abnormal level of substances chiefly nonmedicinal as to source in cerebrospinal fluid
R83.4 Abnormal immunological findings in cerebrospinal fluid
R83.5 Abnormal microbiological findings in cerebrospinal fluid
R83.6 Abnormal cytological findings in cerebrospinal fluid
R83.8 Other abnormal findings in cerebrospinal fluid
R83.9 Unspecified abnormal finding in cerebrospinal fluid

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.

FY2012 Added to the draft code set draft Abnormal findings in cerebrospinal fluid
