Other disorders of central nervous system (G96) ICD-10-CM
The G96 code range covers other disorders of central nervous system with 20 ICD-10-CM diagnosis codes. 14 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the G96 range.
Central Nervous System Disorder
A non-neoplastic or neoplastic disorder which affects the brain and/or spinal cord.
Cerebrospinal Fluid Leak
Discharge of cerebrospinal fluid through a hole through the skull bone most commonly draining from the nose (CEREBROSPINAL FLUID RHINORRHEA) or the ear (CEREBROSPINAL FLUID OTORRHEA).
Dura Mater Tear
Injury to the dura mater, with or without damage to any other layer of the meninges.
Intracranial Hypotension
Reduction of CEREBROSPINAL FLUID pressure characterized clinically by ORTHOSTATIC HEADACHE and occasionally by an ABDUCENS NERVE PALSY; HEARING LOSS; NAUSEA; neck stiffness, and other symptoms. This condition may be spontaneous or secondary to CEREBROSPINAL FLUID LEAK; SPINAL PUNCTURE; NEUROSURGICAL PROCEDURES; DEHYDRATION; UREMIA; trauma (see also CRANIOCEREBRAL TRAUMA); and other processes. Chronic hypotension may be associated with subdural hematomas (see HEMATOMA, SUBDURAL) or hygromas. (From Semin Neurol 1996 Mar;16(1):5-10; Adams et al., Principles of Neurology, 6th ed, pp637-8)
Tarlov Cysts
Perineurial cysts commonly found in the SACRAL REGION. They arise from the PERINEURIUM membrane within the SPINAL NERVE ROOTS. The distinctive feature of the cysts is the presence of spinal nerve root fibers within the cyst wall, or the cyst cavity itself.
About the G96 Code Range
These disorders include cerebrospinal fluid leaks, problems affecting the membranes around the brain and spinal cord, and low pressure inside the skull.
G96.0 separates fluid leaks by head or spine and distinguishes spontaneous leaks from other leaks. G96.1 includes dural tears and meningeal adhesions, with a further distinction for perineural cysts under other meningeal disorders.
G96.8 includes intracranial hypotension, or low pressure inside the skull. Its subdivisions distinguish spontaneous, other, and unspecified intracranial hypotension from other specified central nervous system disorders. G96.9 is for an unspecified central nervous system disorder.
