Abnormal level of enzymes in cerebrospinal fluid

This code indicates an elevated or decreased concentration of enzymes detected in the cerebrospinal fluid (CSF) during diagnostic testing. It signifies an abnormal finding that may point to underlying neurological conditions, infections, or other pathological processes affecting the central nervous system.

Assign this code when laboratory results from a CSF analysis specifically report an abnormal level of one or more enzymes. Documentation should clearly state the enzyme(s) affected and the deviation from normal reference ranges, often prompting further investigation into the cause.

• Do not use this code if the specific enzyme abnormality is already classified under a more definitive diagnosis.
• Always sequence this code after the definitive diagnosis, if known, as it represents a symptom or abnormal finding.
• Ensure documentation specifies "cerebrospinal fluid" to differentiate from enzyme abnormalities in other body fluids.
