Other intracranial hypotension

This code signifies a condition where the pressure of the cerebrospinal fluid (CSF) within the skull is abnormally low, not otherwise specified. This can lead to symptoms such as orthostatic headaches, nausea, vomiting, and dizziness due to reduced buoyancy of the brain. It represents intracranial hypotension from causes other than CSF leak or other specified conditions.

Apply this code when documentation indicates intracranial hypotension without a specified etiology, or when the cause is known but does not fall under more specific codes for CSF leaks (e.g., G96.0) or other defined intracranial hypotension syndromes. Supporting documentation should clearly state a diagnosis of intracranial hypotension and rule out more specific causes.

• Do not use this code if a specific cause for the intracranial hypotension, such as a CSF leak (e.g., G96.0), is identified.
• Ensure the medical record explicitly states "other" or "unspecified" intracranial hypotension to justify this code.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it is a co-morbidity.
