What This Code Means
G96.09 is the ICD-10-CM diagnosis code for other spinal cerebrospinal fluid leak. A cerebrospinal fluid leak from around the spinal cord due to causes other than spontaneous occurrence, such as trauma, surgery, or other specified reasons. G96.09 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering other disorders of the nervous system (g89-g99).
G96.09 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code for post-traumatic or post-procedural spinal CSF leaks.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G96.09 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code for post-traumatic or post-procedural spinal CSF leaks
- •Clearly document the precipitating event (e.g., lumbar puncture, spinal surgery, trauma)
