R83.1

Abnormal level of hormones in cerebrospinal fluid

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R83.1 is a billable code used to indicate a diagnosis of abnormal level of hormones in cerebrospinal fluid.

Key Diagnostic Point:

Abnormal levels of hormones in cerebrospinal fluid (CSF) can indicate various underlying conditions affecting the central nervous system. Hormones such as cortisol, thyroid hormones, and sex hormones can be measured in CSF, and their abnormal levels may suggest disorders like adrenal insufficiency, thyroid dysfunction, or hormonal imbalances due to tumors or infections. Symptoms associated with abnormal hormone levels may include neurological deficits, changes in mental status, headaches, and signs of increased intracranial pressure. Laboratory findings may reveal elevated or decreased hormone concentrations compared to normal reference ranges. Accurate diagnosis often requires a comprehensive clinical evaluation, including patient history, physical examination, and additional laboratory tests to identify the underlying cause of the hormonal imbalance.
