Abnormal level of hormones in cerebrospinal fluid

This code indicates an abnormal concentration of hormones detected in the cerebrospinal fluid (CSF). It signifies a deviation from the normal physiological range of hormonal levels within the central nervous system's fluid environment. This abnormality can point to various neurological or endocrine dysfunctions affecting the brain and spinal cord.

Use this code when laboratory analysis of CSF samples reveals hormone levels outside the established normal reference ranges. This is often seen in investigations for suspected neuroendocrine disorders, pituitary dysfunction, or certain neurological conditions impacting hormone regulation. Documentation should clearly state the specific hormone(s) found to be abnormal and the CSF as the specimen source.

• Do not use this code for abnormal hormone levels found in blood or other body fluids; those require different codes.
• Always sequence this code after the definitive diagnosis, if known, that explains the abnormal CSF hormone levels.
• Ensure the medical record explicitly states "cerebrospinal fluid" as the source of the abnormal hormone finding.
