ICD-10 Code G96.09 – Other spinal cerebrospinal fluid leak (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G96.09 – Other spinal cerebrospinal fluid leak
What it is
G96.09 identifies a spinal cerebrospinal fluid leak that is not otherwise specified by a more exact code. It indicates loss of CSF from the spinal compartment, often due to a defect in the dura.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include positional headache, neck pain, nausea, or symptoms that improve when lying flat, along with imaging or procedural evidence of a spinal leak.
When to use this code
Use this code when the record documents a spinal CSF leak but does not identify a more specific type, site, or cause. It may apply after imaging, myelography, or specialist evaluation confirms the leak. Code the documented condition, and avoid assuming a postoperative or traumatic cause unless stated.
Do not use for
Do not use this code for cranial CSF leaks, postoperative leaks with a more specific code, or leaks clearly tied to trauma or a known spinal procedure. Check documentation if the source or site is unclear.
Coding tip
Query for the leak location and cause whenever the note only says “CSF leak,” because a more specific code may be available.
