ICD-10-CM Code R83.8

Other abnormal findings in cerebrospinal fluid

Version 2020 Billable Code No Valid Principal Dx

Valid for Submission

R83.8 is a billable code used to specify a medical diagnosis of other abnormal findings in cerebrospinal fluid. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code R83.8 might also be used to specify conditions or terms like abnormal histological findings in csf, abnormal histology findings, cerebrospinal fluid: protein - increased +, cerebrospinal fluid: protein - increased ++, chloride level - finding, color of fluid - finding, etc

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.

Short Description:Other abnormal findings in cerebrospinal fluid
Long Description:Other abnormal findings in cerebrospinal fluid

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
